We have a molded shower in our Winnebago Journey. I get black mildew or mold on the caulking below the molded shower panel. I have tried spraying bleach on it but the black is still there. Any sugge...
I have some black caulking that shows just a little around the shower at the top where the shower meets the wall. Even after 7 years I still have to double check but there is no mold. It's the color of the caulking. Double check yours. Could be the same material.
