Many of us have experienced the dreaded "Oxiclean precipitate" that sometimes clings with great ferocity to the inside of bottles or carboys after using Oxiclean in a slightly-too-high concentration. I finally figured out how to get rid of it without any sort of manual scrubbing: Star-San!
I had some precipitate on the inside of a growler that I was rinsing this morning, and remembering that white vinegar had helped slightly in the past, I poured about 1/4 oz of undiluted Star-San in the growler and rolled it around. It was very thick, but I could see it dissolving the deposits. I added about 1 oz of water just to thin out the solution, and continued rolling the jug around for a few minutes. Rinsed it thoroughly, and it's spotless!
Hopefully someone else can find this useful.
