Wow, yours is a cautionary tale. When I've used it on recently acquired vintage razors, they're in for a quick "swish" after the scrubbing bubbles and before the polishing. The question begs to be asked again...how long did you leave yours in?
I have to ask why you need both scrubbing bubbles barbicide? They both provide the same level of disinfection and polishing will actually remove contaminated metal, plus most germs don't survive long on metal anyway.
