    Stained developertrays

    I've done a search on this and nothing is coming up - I'm a bit nervous about using a strong gritty scouring paste to clean it up, can anyone advise on what to use that won't scratch the surface of the plastic. Many thanks
    Trish

    Hi Patricia, there is actually a quite recent thread on this. I will try to find it in a sec. Definitely don't use an abrasive cleaning method as that will create huge amounts of surface area for gunk to grow.

    Hi Patricia, that other thread is called "cleaning filthy drums".

    Is it very dirty? I use my fingers with househould detergent, though the trays are never filthy.

    Once or twice a year I use household bleach to clean my developing trays, as long as the trays are well washed afterwards it has never caused any problems, other than that I never bother,it is harmless staining and I have never seen it as a problem,

    Every so often I make up a Permanganate/salt bleach, that helps, other times a dichromate/hydrochloric acid bleach. I'll even try household Sodium Hypochlorite bleac.

    However stains build up that can't be removed, scouring type cleanes can help very short term but actually make the problem far worse in the long term. The stains get into the plastic, they aren't just on the surface.

    A good wash with warm soapy water after every session is the best way to keep rays clean.

    In that drum cleaning thread, a poster writes how a tarnish cleaning compound for silverware (cutlery, utensils) was instantly effective for cleaning developer trays.

    Personally, I like the silver patina on my developer trays. It's kind of a badge of honour, a mark of experience. It is very stable, so it can't be creating much interference or contamination.

    Never apply an abrasive to surfaces that will used for chemicals, especially surfaces that can have different chemicals at different times, and most especially sequentially. I had momentarily thought that fine sand swirled in a glass bottle to scour it might be fine enough, but I was quickly disabused of that notion.

    I never clean my trays with anything but plain water. I consider anything that builds up on them to be normal.
    f/22 and be there.

    no problems with developer stain they should get clean with water

    fixer: a friend told me to use corega-tabs (dont know a name in english) this are tabs to clean your 3rd teeth.
    works well for me
