1) hard water spot remover for glass 2) mold & stain remover gel 3) ceramic coating for hard surfaces I still squeegee after every shower but do not have soap scum/hard water buildup and I haven’t cleaned my shower glass in a couple of months when using the ceramic coating! Make sure to follow the directions on the water spot remover bottle and let the mold gel sit for 3-5 hours. Directions for use on all product bottles. LTKHome LTKSeasonal LTKWatchNow
