I have been using OxiClean to clean out my carboys for a long time now. Fill it up, let it soak a bit and knock everything off with a carboy brush. Well, I picked up a couple of 6 gallon better bottles to try as primaries due to the lighter weight. After transferring a porter which had been in one for 4 weeks I went to clean it and immediately ran into problems.
Since I couldn't use a brush on it I couldn't get the krausen off. I tried the washcloth trick and swirling but most of the krausen wouldn't budge. I tried soaking with OxiClean and hot water overnight and got a little more off. I soaked it for 3 days and got most of it off but had all but given up on the better bottle. After telling my story to the local brew shop owner I picked up some PBW.
I filled the BB with warm water, added the PBW and left it overnight. Holy crap! This stuff is amazing! In the morning the krausen ring was completely gone, I didn't even have to touch it with the washcloth again.
I'm going to have a another one to transfer this weekend and will report back with the results, but so far I think the OxiClean can stay in the laundry room from now on.
