Hi, Could you recommend the best test to test for black mold? The house that I am renting right now has a basement with high humidity, I place a humidity sensor and it is at 80%, I see a lot of water damage in the basement. I only go to the basement to use the laundry machine. Do you think the humidity of the basement and the water that is always there be enough for black mold to grow and affect the first floor where I sleep?

How would I remove mold on the window grout? I have glass block window in my bathroom and the grout is turning black and it’s starting to smell musty.

Did you try bleach? Use bleach to clean it with a brush or something, then spray bleach on it again to kill the other spores?
