Oxy-clean in a corny keg / soda keg, and 'pitting'

[sirDAHNKE]

I recently just had an issue where I left some kegs sitting with oxy-clean for like 5 days. I scared myself thinking I ruined two kegs and the long shafts, which I had soaking in the kegs as well. They all had what felt like pitting on every surface that the water was touching. I pulled out the shafts and ran the green side of a sponge on them and it started to come off. A little elbow grease and the shafts came clean. I tried the same thing on the kegs. I could feel where I scrubbed vertically was smooth, and where I missed still felt pitted. I am sure that whatever is in the oxy-clean crystalized and stuck to the sides. The bottom collected more, and I was able to clean it all off with a plastic putty knife,as to not scratch the keg.

**Edit:
I had some lingering buildup at the bottom with the odd contours. They were hard to scrape at the correct angles and whatnot. I used a little white vinegar with water(about 60:40 respectively) and let it sit for about two hours and I didn't even have to scrub and it came out perfectly cleaned.

Hope it helps!

Funky, never had that issue before, but glad to know vinegar helps! /inmemorybank

A lot of people have reported a film that forms after an extended oxi soak. Any acid should clean it off, it seems to be a function of your water hardness. With soft water I've never had this problem. You can try using PBW next time.
