How can I get black off of the shower grout?

I have tried everything! I am thinking of using concrete cleaner next. Even my shark steamer won’t remove it. It continues to show up. Essential oils, vinegar, baking soda, peroxide, bathroom cleaners, bleach. Nothing gets rid of it or stops it from coming. I’m sure , if it’s mold, it should not be coming. Surely, it’s dead by now. HELP!!!
