Don't know what you are looking for, but periodically I will get some black mold that begins to grow on the tile in my shower (even though I try to squeegee (sp?) after showering)...so I spray with pure Chlorox when I know I won't be going in there for a while. When I come back mold is GONE!
Sprinkle with baking soda. Spray with vinegar. Let dry. Scrub a bit and clean it up.
Baking soda and vinegar paste
I make baking powder into a paste , apply with a toothbrush leave for an hour then rinse.
