Perhaps I'm the only one that did not know about bleach and stainless steel incompatability, but I've now learned an expensive lesson. Just prior to going away for 2 weeks, I put a liberal dose of neat bleach in the kitchen stainless steel sink. On my return, I found that the bleach had eaten clean through the sink, leaving a 10mm x 5 mm hole through to the cupboard below. It also had eaten through the plug chain, which came apart in my hand as I pulled the plug out.
