apartment therapy changing the world, one room at a time

I moved into an older apartment that has a bathtub with jets. I had no idea how to clean them and when I turned them on black stuff came out. I finally met a guy who does bathroom contractor work and he said how terrible it was that people have tubs with jets and don't know how to clean them because the black stuff is mold. The proper way to clean is liquid dishwasher detergent (because it doesn't suds) and a little bit of plain bleach. The bleach is the only thing that kills the mold. Fill up the tub with hot water and let the jets run for a while. No more mold.
