[QUOTE=Kevin A;354440]Welcome to our group! I know that I have some mildew or black mold problems at times, too, and bleach does clean it off.
Thanks for all that information, but none of it worked! Tried white vinegar- useless! White Magic was not available, Other cleaners suggested were too expensive to even consider, so I reverted to a rag soaked in paint
thinners. This did remove it and I will now spray with a coat of clear polythene lacquer to see if sealing the area will keep the stain
