if he has hard water it'll bring all the minerals out.
Really? Why doesn't that happen in a washing machine when using oxyclean to wash clothes?
Obviously there's a dependency on the actual water makeup, and yours might be exceptionally low in carbonates.
Beyond that, have you ever stopped the washing machine mid-wash cycle and left it there overnight to see what happens?
[...]Why would anybody do that?[...]
I'm wondering how much oxyclean was used in those carboys. Could it be that using way too much causes this? I'm just find it hard to believe that oxyclean precipitates minerals out of the water.
soak it in vinegar to get that crap off, or starsan might work... but it needs something acidic if i recall correctly to get that stuff off.
LOL! Of course, but then you don't actually have a counterpoint to offer
hmmm, I use oxy too and leave it until I am ready to use the carboy next.
I just add a scoop and fill with water. After a day or so the carboy is clean and what I thought was the end product of oxyclean (soda ash?) sinks to the bottom like trub.
In any case, I dump and give a rinse, ready to sanitize.
I've never had anything like this happen.
Salt + Vinegar = Hydrochloric Acid. It's the acid that does the cleaning, the agitation of the salt helps.
A little googling pulled up this formula:
HC2H3O2 + NaCl ---> HCl + NaCH3O2
(vinegar) + (salt) ---> (hydrochloric acid) + (sodium acetate)
However, I am not a chemist and don't profess to be one. This formula may be incorrect. I know it cleans copper very, very well though.
