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...
Two suggestions: First tackle the mold with Oxyclean and a toothbrush. Make a paste and rub it in and let it sit for a few hours (throw out the toothbrush!), then spray the area with Concrobium and let it dry. Concrobium can be purchased at many hardware stores. BTW, if the mold doesn't come clean with step 1 it is below the caulk as others have said.
