I think I may have really messed up soaking my stainless fermenter in the 3:1 Oxyclean/TSP mixture. I soaked it first overnight with hot tap water and noticed what looked like filmy areas near the top of the water level. So yesterday after I finished a boil-off test, I tried to soak it again using the near boiling water and more Oxy/TSP. After a few hours I emptied and the filmy areas had gotten bigger. Scrubbing with BKF did nothing, and it looks like the stainless has been etched by the soaking. Has anyone ever had this happen before? Its making me sick thinking I ruined my $175 Brew Bucket, but I've seen nothing saying that it would be hurt by this.
