Clear silicone is commonly used as silicone caulk to seal and protect sinks, bathtubs, and surrounding areas from moisture damage. Over time, clear silicone can turn yellow and black due to exposure to rust and the growth of mold. Fortunately, you can easily remove the yellow stains from clear silicone at home without spending a lot of money on cleaning products.

Step 1

First, dip a plastic scrub brush into a mixture of soapy water.

Step 2

Next, scrub the yellowed silicone with the soapy water. Then, dry the area using a soft towel.

Step 3

To protect surrounding areas like flooring or a bathtub, cover them with paper towel.

Step 4

Fill a plastic spray bottle with bleach.

Step 5

Spray the yellowed silicone with the bleach and let it sit for 15-20 minutes. This will whiten the silicone and eliminate any mold or mildew.

Step 6

Wear rubber gloves and scrub the clear silicone with a plastic scrub brush.

Step 7

Rinse the bleached area thoroughly with cool water and use a soft towel to remove any residue left by the cleaning products.
