How to Clean Silicone Off of Bathtubs
Known for its resistance, flexibility and strong adhesive properties, silicone caulking seals moisture out of bathtub joints, which is vital to preventing leaks and deterioration. Although silicone caulk lasts around 20 years, dampness and humid bathroom conditions increase its vulnerability to mildew. Mildew also consumes soap scum, body oils and grime accumulated on caulk joints, causing caulk to decay and weaken. Besides mildew infestation, silicone caulk eventually ages with time and loosens its grip on joint surfaces. Improve the look of your bathtub by removing old or moldy silicone caulk.
