Clean silicone seals in tile, bathroom fixtures, countertops and all around your home by combining two household products you may already have. Silicone is a resilient material that stays soft and flexible to hold securely in place while sealing out liquid. Cleaning silicone seals with abrasive scrubs and cleaners may scratch or break the seal and make it ineffective. Carefully wash your silicone seals to restore them to a like-new appearance without causing expensive damage.
Pour baking soda and liquid dish soap into a bowl and mix them into a paste with an old toothbrush.
Apply the soapy paste to the silicone seals by lightly brushing the paste covered toothbrush over them in a circular motion.
Allow the paste to dry on the seals for a couple of hours before wiping it away with a soft damp sponge.
Apply a second coat of baking soda paste if grime remains on the surface of the silicone seal. Dry and wipe clean.
Avoid using vinegar on silicone seals--it is known to degrade them and cause leaks.
