Silicone is caulk.
Thank you William can you suggest a good quality silicone caulking for a bathtub. Also do you have any suggestions for getting black mold mildew from bottom and around shower stall
Any brand of kitchen and bathroom caulk will work. Has mildewcides in it. I like DAP.
Bleach will clean the mold. Rinse well. Then use vinegar to kill mold spores. Do not mix both together. The fumes are harmful.
