Default Can I use this Carboy?

So I found a couple of carboys in an out building on my grandpa's farm. They look like they have some residue clinging to the inside so I filled them up with a bleach solution and let them sit about a week. Rinsed them out and the residue is still there. So I thought maybe the residue is alkaline and needs to be dissolved in acid so I filled one up with Star-San and left it alone again for about a week. No luck. Still appears to be something sticking to the inside. I have no idea what was ever in these carboys or how long they've been there, but now I'm thinking that they may have been cleaned with some type of lye based cleaner which left a slight etching. Are they usable despite their appearance? Can etched glass be made sanitary? As I look at the photo it occurs that I should add that scrubbing had no effect whatsoever, before or after soaking.

If neither of those had an affect, did you try sticking your finger down in there and seeing if you could scratch some off with your fingernail?

If there's nothing to scratch off, it maybe possible that something chemically etched the glass on the inside and in that case, it would probably be ok to use it.

If you can scratch something off, then there's something else going on and I probably wouldn't use it.

Just an idea.

i'm assuming you've used a carboy brush with no effect. i would try the suggestions listed above, but if they don't work, i would not use the carboys for fear of infectious organisms taking up residency in the etches.

any idea what the carboys were used for? might have originally held pesticide or caustic chemical that left the etches.

A brush had no effect. I did reach a finger in and not only could I not scrape it off but I couldn't even feel it. It feels as smooth as the glass. I guess I'll try the Oxyclean.

This might be a really dumb question since I've been drinking some homebrew, but....is it on the outside?

People here are being awfully cavalier about tossing a really nice find. If I didn't feel anything on the glass after a good oxy soak then I would use them without a second thought. Plastic is probably more porous than that etching if that is what it is.

It might be a mineral deposit in which case vinegar and salt could help.

Be VERY careful if you use hot water.
