Only StarSan for cleaning?

[IslandLizard]

I do use a generic version of Oxiclean [...]

There's nothing wrong with using a cheap generic Oxiclean for routine cleaning. The washing soda component is a great cleaner/degreaser by itself, especially when warm (be careful with using hot liquids in glass and plastic fermenters). After the percarbonate lost its loosely bound oxygen it becomes washing soda too. The released oxygen helps in destroying organic deposits and content.

I routinely use simply washing soda for all around cleaning brewery equipment, generic Oxiclean where the added oxygen is helpful, and (homemade) PBW where the added benefit of metasilicate counts. Near boiling PBW is very useful in recirculating my plate chiller loop, cleaning the hoses at the same time. I often add some lye (NaOH) to it for extra umph.

I sanitize with a mixture of 1 Tbsp. bleach per gallon of water and then rinse well afterwards.

Not using Starsan?

I also use StarSan acid sanitizer for both cleaning and sanitizing the keg after use and also for removing any cooked on stuff from the bottom of the brew kettle. The acid sanitizer does have a somewhat oily feel to it so rinsing well after use is very important. Also I use the StarSane acid sanitizer for cleaning around the house... For example the stove top when it gets gunked up. I love the stuff.

 

[coonmanx]

Not using Starsan?

No. As I said before I use a very dilute bleach mixture and it works great. Rinse well and there is no flavor imparted to the beer at all. Been using it for over 30 years. LOL. Never had any issue at all. You do know that they are even recommending bleach as a cleaner that is effective against coronavirus....

 

[coonmanx]

Byron Burch actually talks about using bleach on page 59 of his book "Brewing Quality Beers". But he talks about it like nobody does it anymore and then suggets iodophor sanitizer instead. I don't remember where I actually first ran upon the suggestion of using bleach for sanitation. It may have been from Papazian. Burch does mention that it could leave a flavor if not rinsed because of questionable water, but I don't have that issue and I do rinse after sanitation and before storing the carboy upside down on a carboy dryer for a few days.

Who knows, I could be the only homebrewer in the world that still uses it but that is OK with me because it is cheap and effective. Suits my needs.

StarSan acid sanitizer for both cleaning and sanitizing the keg

StarSane acid sanitizer for cleaning around the house

Starsan is a rinse free sanitizer, not a cleaner. Its cleaning capabilities, aside from killing bacteria, are near nonexistent.

To paraphrase Palmer: You can't sanitize something that's not clean in the first place, i.e., you can't sanitize dirt.

It actually works really good on grease buildup on the stove when used with hot water. You can even use boiling water to give it some extra oomph. It's acid properties are what provide the cleaning properties of it. Phosphoric acid to be exact. You should try it sometime and then come back and comment. Just saying. It works.

I will even use it on a hard to clean plate if there is some buildup on it. A drop or two there and it turns regular dish detergent into super dish detergent. Great stuff. It works much like oven cleaner which also contains an acid. But it has no bad smell.

Comment deleted...

But yes it does work well for cleaning walls and other things around the kitchen. Great for removing grime. Try it.

Also I have heard many times from other brewers that they will use it for an overnight soak to remove grunge from various things, especially anything that is stainless steel. When I have transferred my wort to the fermenter I will use a few drops of it on the bottom of the brew kettle. Use a green scrubbie to clean it back up to shiny again. Then rinse well.

 

[coonmanx]

Just wanted to add how I use it with the keg. When the keg is empty and all of the delicious beer has been consumed... I first rinse the keg with water. Then I take a flashlight and look inside. If I see some deposits I take a small dab of Star San on a green scrubbie and reach in and hit those areas. I have fairly skinny arms so maybe that would not work for others but you could also use a long brush. Rinse again. Then I fill the keg with the 1 oz. per 5 gallon mixture of StarSan and let it sit for overnight usually. Use the CO2 to blow it out through the serving hose. When it gets down to about half empty I then usually just dump the rest in the sink. Fill completely with water to rinse and do the same thing. Once it is empty it gets stored upside down and then is sealed off until the next use.

It's fine if that "works" for you and you just don't want to change, but Star San does not adequately remove organic residue and therefore should not be used by itself as a cleanser.
This recommendation is backed by both science and empirical evidence -- plenty of brewers report contamination when using only Star San for cleansing.

Each to his own. I go by what my eyes see and I am not running a brewery either. It works as a cleaner. At the restaurant where I work we use an oven cleaner that contains an acid as well. It smells horrible and you are not supposed to breathe it in. So the StarSan has similar cleaning properties but without the smell.

Not exactly the same thing but they both are phosphoric acid and it has cleaning properties.

The bottom of my brew kettle is shiny when I am done using the StarSan on it. Same with the keg. I have never had any sanitation issues at all. So I don't see a problem here.

Also if you read my earlier posts I am not using it to clean my fermenter. For that I am using OxiClean. Big difference. Also I am not using it to sanitize my fermenter either.

Just read the instructions on that document. It requires scrubbing and they suggest other agents are needed as well.

I go by what my eyes see

We're working to prevent microscopic contamination, so we can't exactly trust our eyes when determining the best practice.

There's no reason to use different cleaning processes for fermenters and kegs, they're both cold side equipment and both have extended contact with the beer/etc.

I will go with my 33 years experience and the fact that I have not once ever had a sanitation issue. But please. let's create problems when none exist. The proof is in the final product and I recently served up a 5 gallon keg to friends that lasted all of 3 hours....

Just sharing my experience. If someone does not want to do things that way then that is their choice. Nobody is forcing anyone to listen to anything that I say or do anything the way I do. It's still a free world.

When evaluating risk using a certain practice, it's important to look at failures more so than successes. The first 2 guys playing russian roulette might recommend it as a fun game good for parties.

If your Star San only process works for you, that's fine, but it's not a good process to recommend to everyone. Others might have other differences in their methods that make it more risky. Hope that makes sense.

The only thing I want to add is that recently we had an "Ice Bowl" disc golf event here in Colorado Springs. I brought a keg of my brew and there were two kegs from a local brewery. My keg was gone in 3 hours time and the other two kegs were not even close. I got comments like "You should bottle and sell this beer". So I have a certain amount of confidence in how I do things and sleep pretty well at night. I am pretty meticulous when it comes to cleaning and sanitizing. You may disagree and that is fine but I'm not going to worry about something that is a theoretical possibility. That is just not in my nature.

 

[coonmanx]

You know, I don't remember whether I have ever used some OxiClean or PBW on the keg for cleaning it. I might have. I might even do it next time before using the StarSan. I have plenty of it.

I do have a bunch of One Step cleaner that a friend gave me.

Now that cracked me up!

It's not just theoretical. Other people using just Star San actually do get contaminations.

 

[coonmanx]

Of course I would generally say "prove it". Also you don't know their procedure, how they actually sanitized or failed to do so....

Here is something to know about me. My great grandfather was a brewer, although in a time when it was probably not as legal as today. My dad told me stories about the beer being "ready" when the bottle caps from the bottles stored in the basement would shoot off and hit the bottom of the floor. So obviously they didn't have that great of carbonation control back then.

I am a brewer but consider myself to be much like a chef. I create a recipe from raw ingredients much like a chef. A chef creates a dish while I create a beer. It also takes longer for me to "serve" the final product.

I don't sweat the small stuff. In Russian roulette someone could get their head blown off. If something happened to one of my batches I might lose 5 gallons of beer and have to start over. This recently happened but had nothing to do with sanitation. I had a fresh keg of Apricot Honey Ale that was delicious. I told some dics golfers down in Pueblo, CO that I would bring it the next morningto share with them. But first I wanted to share it with a friend. So I took it over there in my "new" car which I recently got (a 1999 Ford Escort ZX2). When I went to hook it up I realized that I didn't have a flashlight to check the keg connections. I tried to get my friend to use his smartphone for a flashlight but he didn't know how. LOL. So we sat and drank for a few hours and when I went to leave the keg was almost empty. I soon figured out what happened, that there was a serving side leak while I was applying serving pressure. I usually disconnect the gas from time to time on a keg but this keg never got too foamy and that should have raised an alarm bell. But it didn't. So the entire keg got wasted on the ground. I was super depressed for a day and then immediately ordered the ingredients for a Mango Honey Ale, which I brewed about a week later. Got right back on that horse.

I don't really sweat the small stuff and maybe that is just me. I only have so many days left on this rock so why not enjoy them? Life is too short.

My 2 cents....

 

[coonmanx]

You know, technical brewers can make technical beers but maybe they don't make that one beer that sweeps you off of your feet. There is something to brewing, much like cooking, that doesn't come from a book but from the heart. I brew from the heart and usually don't drink the majority of the beer that I make. It all gets shared because that is my way of giving back to the community. And to me, if they like it, then I like it.... Maybe that helps others understand my point of view. If I make a mistake then I will learn from it. But right now things in the brewing world are going pretty well. I plan on then staying that way....

 

[coonmanx]

It's not just theoretical. Other people using just Star San actually do get contaminations.

In order for this to be a relevant statement you would have to provide actual data from all people who just use StarSan and what percentage of them actually get contaminations. That would actually be providing evidence and not just a blanket statement about "other people".... I would actually like to see that data set.

 

[fendersrule]

I used to use only Star San in the past. I "thought" it was a cleaner as well as a sanitizer.

Six batches in, I started to get infections. Took me forever to figure it out. I went from improving fermentation temps, to doing other "improvements" that were completely unrelated to the problem at hand.I told everyone who was trying to figure it out with me that I've been cleaning everything.

I went through a "bleach" cycle on everything and re-brewed.

Infected again.

Then I found out the problem: I wasn't using a cleaner for my fermenters. Ever since I started using PBW, I haven't had an infection since (about 8 batches so far since). My beers have never tasted better.

If you only use Star San to clean, it will come up and bite you eventually like it did me.

Miracle Sealants Company - Phosphoric Acid Cleaner

From their MSDS:
Specific gravity: 1.22

That comes out to a concentration of around 45% 35% Phosphoric Acid.
No mention of other ingredients.

From the product data sheet:
Deep Cleaning Action for Most Concrete/Masonry Surfaces

Mold, Mildew and Bacteria Sanitation:
For best results in killing mold, mildew, bacteria and other micro organisms, use Miracle Wipes as directed.

 

[coonmanx]

A couple of things that have not been mentioned here. First is the fact that when I use the StarSan for clening the keg and removing debris I have my arm inside the keg and I am using a green scrubbie and physically removing debris by scrubbing. The StarSan is used full stregth. I have no idea how fendersrule was doing it or if he was in any way using a similar method to the way I am doing things. That matters.

Secondly, it is just as important how the keg is handled once all of the cleaning, sanitizing and rinsing has been completed. How is the keg dried and then stored?

Here is what I do. After I run everything through the keg I turn it upside down and rinse it by holding it over the bottle washer. I then let it sit for a minute or two upside down on the divider between the two sink halves to drain. Keeping it upside down is very important so that nothing can get in it. When it has drained for a few minutes I then take it, still upside down, and put it on a clean towel to dry. It dries for a few days and then after that I flip it over and there is usually a small amount of water in the bottom of it that probably came from the pickup tube. I reach in with clean hands and a clean paper towel and mop that up. Probably the only way I could prevent that small amount of water from staying there during the process would be to run some gas backwards through that small tube to blow it out while upside down. That should work.

After I am confident that the keg is fully dry I then seal it off and store it until I am ready to use it. This means two things. First, nothing can get inside the keg at this point in time. And second, bacteria needs moisture to survive. The keg being completely dry prevents bacteria from existing in the keg as it can not live on a dry surface for any amount of time. That is the science.

Not trying to beat a dead horse here and I doubt that I will convert anyone to doing things exactly like I do. I also may use some cleaner on the keg the next time I go through the process. But I will soon have another batch in the keg and I am confident that it will be just fine. But that is me.

Also as far as mold and mildew go.... I used a small green scrubbie with some StarSan on it in the bathroom to combat some black mildew that I saw growing on the ceiling above the shower. Before that I had only ever tried using bleach and it would kill it off for a small period of time before it came back. When I used the StarSan the black mildew not only disappeared but it never came back. Also remember that I am basically using it full strength in these situations. When I am reaching into the keg to use it to remove buildup I am putting it full strength on a green scrubbie. It's acidic power is a lot stronger when used like that. These details are very important to the discussion. Did fendersrule physically reach into his keg and scrub the sides down with a green scrubbie and some StarSan while cleaning the keg? I don't know.

You may now return to your regular programming. Just wanted everyone to have all of the information and not make any assumptions.

I highly doubt in the world of homebrewing that reporting contaminations is ever going to be something that anyone could put into a report.

Read the "is my beer ruined" threads. A ton of them are because of improper cleaning and sanitation.

Remember that once Starsan dries it is no longer effective as a sanitizer. Thus sanitizing and then storage of an open container is a waste of Starsan. (Closed containers would remain sanitary - inside) You need to do sanitize again before use. If not you are like those kids playing Russian Roulette.

We are not really saying your procedure is not effective - for you it is. We are saying that just because it has worked for you doesn't make it good advice. I have used utensils that I forgot to sanitize without infection, but I would not advise doing that. I would not say the unsanitized utensils are not a concern based on my experience.

And I get that but please can we stop using the Russian Roulette analogy. We are not talking about people getting their heads blown off. We are talking about beer. Also bacteria needs moisture to survive so storing a clean, dry and sanitized keg sealed up is a good way to do things no matter how you get there. Bacteria can not live for very long without moisture. That is science. And long ago they figured out that bacteria can not get into a sealed system. We learned that back in eighth grade biology. So in fact, the longer my keg sits there sealed up and dry, the less the likelihood of any contamination surviving and that is science. Go look it up.

I have never seen dried up StarSan so I don't even know what that means....

 

[coonmanx]

Pasteur's experiment... And he did not even used a sealed system but one in which things could not fall down into the liquid....

https://science.howstuffworks.com/innovation/scientific-experiments/scientific-method5.htm

But this is why I dry things upside down. Because it is a simple and effective way to prevent anything from falling into it. I also run a HEPA air filter in the room where I dry my keg.

Sealed is the key here.

Dried up Starsan is not just dried up Starsan. It is a utensil that had been sanitized with Starsan and allowed to dry. An example of what I am describing would be a stir spoon. You sanitize it with Starsan and use it while it is still wet. If you then clean and rinse it and store it for use on your next brew day it is only still sanitary until the Starsan dries. Once dry it is no longer sanitary.

And once again that depends on how you store it. If it were stored in a sterile environment then it should still be sterile unless there was something there that had recontaminated it. In my case the keg has been fully dried upside down and then sealed. Once that happens nothing can get in and nothing can get out and bacteria needs moisture to survive.... Please show me an example of bacteria living for more than a short anount of time on a dry surface. You can't because it does not happen.
