I use a magic eraser to clean up mold on all kinds of surfaces in our bathroom, our white fences outside, etc. I wasn't sure what you were using it for, but a magic eraser should do the trick!
Connie,. Use Home Armour mold and mildew stain remover 2x the power. It is a white and yellow spray and the bottle is a light green. I get it at Home Depot, follow the directions, and the mold disappears. Aloha!
concrobium in a sprayer ... it will kill the mold spores that 'grow' in the pores of the paint, or surface on which it's growing; you can use bleach, vinegar, 'magic erasers', etc., but they won't kill the underlying spores and the mold will eventually return.
