Keeping a mixture of star san

[fishnfever]

I would like to keep my starsan for than one use. Could I just keep a glass carboy full of a starsan mixture and just seal the top with saran wrap ans a elastic.

I don't know for starsan, I know for iodophor it goes 'inert' in a few months if I remember, meaning it loses its efficiency and becomes useless after a while. I'd read the box? Or google for the starsan website?

Edit: nix their site, its garbage

I keep star san for a long time. What I do is mix the star san using 5 gallons of store bought distilled water. I then use the 5 one gallon plastic jugs to store the star san when I am done using it. This works out pretty well and allow me to just pull a single gallon out when I take a sample or something like that. I tried the carboy, but I ended up with a film on the glass after a while.

I mix a 1 gallon jug of Star San and keep it a month or 2 then make another batch.

check your StarSan PH if it drifts above 3 add a little more StarSan till the PH drops below 3 again. you lhbs will have PH test strips. just dunk and check the color.

Star-San in distilled water lasts the longest, in my experience.

I have used starsan in distilled water for up to 4 months with no contamination problems. I simply mix 1 gallon of DI water with 6ml of Starsan. From that gallon I then pour some into my spray bottle when I need it.

I've found the best way is to make starsan up in a spray bottle. It's a waste to have 5 gallons of it when a fraction of an ounce is enough to cover the surface of something and that's all you need to do. Mix it up in a spray bottle, spray down whatever you need sanitized and you're done. My spray bottle holds about a liter of starsan and I only have to fill it up every 3 or 4 batches. My wife even likes to use it to spray down cutting boards and stuff. I bought the small bottle of starsan over a year ago and it's still over half full.

I will be picking up some new spray bottles then, I'm going through that stuff fast as hell

I would definitely suggest that. It's much cheaper easier and far less messy than working with a bucket full of starsan and mixing it up everytime you need it.

I use Distilled water and mix a gallon at a time . Some goes into a bottle sprayer and the rest goes into a 2 gallon garden sprayer .
