Not bad.
I noticed you have a page dedicated to safety up front. That is good, but you are missing any information about Hexavalent Chromium. If you are not familiar with this then you need to educate yourself. The problem arises when we use stainless steel in an electrolysis environment. Hexavalent Chromium or Cr(VI) is really bad stuff. The movie Erin Brokovich shows just how bad this stuff is.
There are two methods for proper disposal. 1) label it and take it to your local hazmat collection point. 2) find some way to convert the Cr(VI) into the safer Cr(III)

Unless you have done the second and tested safe, please don't dump your electrolyte down the drain.
