    Chemical Cross Contamination

    Guys, I am looking for some advice please

    I have always been circumspect about cross contamination, so Developer Trays are separate from Stop & Fix Trays.

    I have never worried to much about mixing up Stop & Fixer Trays.

    I also keep Selenium Toner Trays separate from any others.

    However, I am curious as to whether I should keep Trays for both HCA & Gold Toner (Tetenal) separate from any/all the others

    Thanks

    Martin

    HCA won't contaminate any tray, anyway the main ingredient is in many developers, Sodium Sulphite. Gold toner will at the worst deposit gold on the tray surface and again pose little if any contamination problem at all.

    Thanks Ian

    I didn't expect there to be a problem - but photographic chemistry isn't my strong point - so I thought it better to ask.

    Regards
