There is a difference between a stain and mold. A mild solution of bleach and water will kill the mold, rinse thoroughly afterwards. Stains may not come out, but aren't a health risk. I would try a scotchbrite sponge with a little dawn dishwashing soap and maybe a little bleach afterwards.
I'm tired of fast moves, I've got a slow groove, on my mind.....
I want to spend some time, Not come and go in a heated rush.....
