Default How to clean stains off a glass carboy?

Hello to all!

I have an old glass carboy a friend gave me because I'm just getting into home brewing. He had used it years ago (maybe 7 or 8 years) to try his hand at brewing, but never really got the hang of it. So he let it sit in his storage shed, laying on its side in the Texas heat for years.

I guess he didn't wash it out properly before he put it in there because there are numerous black/dark brown stains on the inside of the glass.

I tried filling it up half way with water and adding in some OxyClean then filling it up the rest of the way. I let it sit for 36+ hours and that did remove some of the stains, but not the thicker/darker ones. I also tried using a bottle brush to scrub them off, but it didn't really work that well.

Does anyone know of a better chemical/product/whatever to use to remove these stains, or is this carboy beyond cleaning, and I should just pitch this one and buy a new one?

I did a search on here but couldn't really find any information that could really help me out, but if someone knows of a thread that already exists, please point me to it!

Thanks to anyone who can help shed some light on this for me!

David

PWB works pretty well. Put 5 tablespoons in and fill it to the top with warm water and let it set for a few days. If that does not work, then get some Starsan, put two tablespoons in it and let it sit for a week. It can take paint off the outside of a Corona bottle, so I bet it would eat through whatever stain is in there. If that does not work, get a Better Bottle. You won't cut off your fingers and you back will thank you.

I agree with Edwort but after trying the PBW make sure you rinse the carboy out completely before trying the Star San, The PBW will weaken the Star San.

Thank you EdWort and Monster Mash for your speedy replies!

I'm guessing by the name (Powdered Brewery Wash) that this cleaner is only available at homebrew shops or online. Or is this something that might be found in a more common-place store such as a Wal-Mart, Target, Home Depot, etc?

The reason I ask is that the closest home brew store that I'm aware of in my area is about 30 or 35 miles away. I'd rather purchase some locally than wait for days or a week for an online order to arrive.

I'll certainly give both suggestions a try and let you all know how this goes!

Thanks again!!

I would toss in the same amount (5 TBS) of Oxiclean in the carboy and fill it up with warm water to the top and let it sit till you get your PBW order in.

You can also try a product called TSP. It is amazing at removing crud. I use it when Oxyclean doesn't get the job done. You can also add one tablespoon of bleach to it in 5 gallons, which improves its effectiveness.

I use OxyClean for everything. I have a new tub of PBW that I had on order when I bought the Oxy, and still haven't opened it. I think Oxy works better and is cheaper to boot.

Maybe some kind of acid? CLR?

On a very related note, for anyone who has ever purchased any of these Outdoor Cleaners, for cleaning your decks and walkways and what not, read the label sometime. All they are is a mix of TSP and bleach... I now buy the two separate and mix them in a garden sprayer and save bucks.

I bet strong bleach water will get it in a few days. Be sure to rinse throughly after. Short of that a carboy brush and some elbow grease.
