White deposit on carboy

[Charlietuna]

A 5 gallon carboy I picked up yesterday has a white mineral type deposit around the bottom. I've had it soaking in Oxyclean for a day & been scrubbing with a carboy brush & also cut a piece of scotch brite pad & tried to scrub it using a piece of 1/2 inch pvc pipe.

the carboy has come a long way, but still a few spots of this white deposit.

Any other suggestions? CLR type cleaner?

Thanks,

Brian

Could it be limescale?

When I get reluctant stains, I attack it with a bottle brush in a battery drill.

If it is limescale, vinegar could possibly shift it. Cheers, Tony.

I was thinking about some type I'd scotch bright pad attached to a long rod the I could use with the drill. Maybe a gun cleaning kit? Hmm. That's an idea.

Thanks.

You could add some vinegar and rice (uncooked). The rice would act as the abrasive part to remove the deposit.

If all else fails add a few drops of CLR if you believe it's clacium. Then wash thoroughly. The glass won't retain any of the CLR.

I have used muriotic acid to remove deposits. Worked good but be sure to rinse well.

You could also try B-Brite and if the doesn't work try Caustic soda. Use extreme caution with the caustic as it is very dangerous to you if you get it on your skin.

I had emptied the carboy & set it aside Saturday & just looked at it this morning. The white all over the inside was still there, I thought I had it, but when it dryed, it came back. Im soaking / sloshing CLR. I tried vinegar earlier this am, but didn't seem to do much. It may not be mineral build up. We'll see.

Thanks,

Has anyone used sand? I was thinking about filling it up with oxyclean & water & a scoop of sand from my kids sand box. Then setting it under the drill press for a while.

Will this scratch it?

Thanks,

Don't use sand. You'll scratch it bad. If it hasn't cleared up after all this don't worry about it. Your wine will be fine.

I was also thinking that the wine would be ok the way it is. The clr did help a bunch. I may try it again. Just set it on the counter for a few days & shake t every time I walk by.
