Question:

What is the best way to remove the yellow stains that some of my chrome platers acquire during the workday? S.C.

Answer:

I hate to say this but in 2001 the plating industry should not have to deal with the problem of staining due to chromium plating solution. That's why gloves and other safety devices (eye protection, aprons, etc.) were invented. Yes, it is a pain to wear gloves all the time when working around plating tanks, but it beats the alternatives of skin infections and permanent scarring. There are skin creams of various types that can be applied before the start of work that will also work, but I prefer gloves.

A direct answer to your question is to use a solution of 4 oz/gal of sodium thiosulfate to remove the stains. This should solve your problem without causing skin dermatitis. However, this is not recommended as a replacement for good safety practices.
