White silicone can turn yellow due to a number of different factors, but generally, the cause is due to sunlight exposure or reaction to chemical contaminants. Sunlight is the most common cause of yellowing of silicone, particularly when the silicone is exposed to direct rays or has a poor UV inhibitor.
Over time, the sunlight causes the silicones to become discolored leading to it changing color from white to yellow. Chemical contaminants can also cause the silicone to yellow. For example, ozone, sulfur-containing compounds, or oils that react with the silicone and cause it to discolor.
If the silicone is used in an industrial setting, it can discolor from excessive temperatures, which can create thermal oxidative reactions, leading to a yellow discoloration.
How do you get yellow stains out of white silicone?
Removing yellow stains from white silicone can be a tricky process, but there are a few methods that may help.
One option is to scrub the yellow stains with a soft toothbrush and a diluted solution of water and bleach. Mix approximately five parts of water with one part bleach, and then use the mixture to scrub the stained silicone.
This should lift the yellowing from the surface. Be sure to rinse the silicone thoroughly afterward.
Another option is to use a citric acid-based cleaner, such as lemon juice or white vinegar. Just make sure to test a small area first to make sure the cleaner won’t discolor the silicone. Once you have verified that the cleaner is safe to use, apply a small amount to the stain, and then scrub gently with a soft toothbrush.
If the stain persists, you may need to use a degreasing agent. Mix a small amount of dish detergent with water and then apply it to the stain. Let it sit for a few minutes, and then use a soft cloth to scrub away the stain.
As a last resort, you can use a silicone-safe caulking remover, but it should be used with caution. The remover may lighten sensitive areas, so it’s best to test it on a small, inconspicuous spot first.
If all else fails, you may need to replace the white silicone entirely.
