For more stubborn stains, we recommend soaking the item in a solution of baking soda + water or white vinegar + water for several hours. If you are still unable to lighten the stains, try soaking in the solution at full strength (just white vinegar or just baking soda) without diluting with water.
Remove Discoloration From Silicone
Place the discolored item in a bowl or sink and pour on enough hydrogen peroxide to cover the stained area. Let it soak for 24 hours. Rinse well before using it.
good news is that this yellowing is temporary and it can be removed with normal household cleaning products, simply spraying some household bleach onto the silicone and allowing it to sit for 10-15 minutes before rinsing it off will get rid of the yellow color.
It could be exposed to UV radiation (sun), heat, or chemical (humid climates count as chemical exposure). Whatever harmful condition the sealant is at risk of being exposed to (could be all three), it is still possible to minimise the chance of it yellowing.
It can also interfere with nonstick cooking properties. To clean these silicone utensils you'll need hydrogen peroxide and baking soda. The hydrogen peroxide will also remove any stubborn stains left behind.
In a small basin that can fit all the silicone rubber items you'll need to clean, pour hydrogen peroxide enough to cover the stained items. Let them soak overnight. The next day, remove the items and rinse them with clean water. You can also opt to double-clean them with a soap dish and a sponge before rinsing.
All neutral cure silicones will yellow due to oxidation of one of the raw materials. The problem can be exacerbated if the silicone is in a dark closed room, away from daylight (UV). It can be reversed by exposing the silicone to daylight, but over time it will eventually yellow.
For more stubborn stains, we recommend soaking the item in a solution of baking soda + water or white vinegar + water for several hours. If you are still unable to lighten the stains, try soaking in the solution at full strength (just white vinegar or just baking soda) without diluting with water.
Make a solution of equal parts white vinegar and water. Soak the silicone item in the solution for 30 minutes. Scrub gently with a soft brush. Rinse thoroughly with clean water.
You might see vinegar, a combination of baking soda and vinegar or bleach recommended as cleaning solutions for silicone sealant elsewhere. However, although these products may work to some degree, they do not kill the spores and have the potential to damage the sealant bead.
Toothpaste Scrub
Toothpaste is not just for your teeth; it can also be an effective cleaner for silicone cases due to its mild abrasives. Steps: Apply a small amount of non-gel toothpaste directly onto the yellowed areas of the case. Use a soft-bristled toothbrush to gently scrub the surface for about two minutes.
The Processing of Clear Silicone
When clear silicone products are formed, the main reasons that cause the color of clear silicone turning yellow after molding are: The mold temperature is too high; The vulcanization time is too long; The second time vulcanization.
In summary, while rubbing alcohol can be used to clean silicone products, it's essential to limit exposure to prevent potential long-term damage. By understanding the interactions and following proper cleaning methods, you can maintain your silicone items effectively.
Yes, white vinegar will remove mould from silicone sealant in your bathroom. Apply it directly or mix with baking soda for extra cleaning power on stubborn areas. Let it sit, scrub, rinse with cool water, and dry the area completely.
Whether you're using your silicone spatula to stir marinara sauce or freezing chilis and stews in your Souper Cubes, stains can occur. Cleaning with hydrogen peroxide will help remove both discoloration and sticky residue.
Use rubbing alcohol: Rubbing alcohol can help remove stains from your silicone phone case. Use a cotton ball or cloth to apply rubbing alcohol to the yellowed areas of your case and then simply rub it until the yellow colour fades away.

Does Silicone Suffer from Discoloring? Unfortunately, clear silicone will eventually discolour. If you have clear silicone in your home (perhaps being used as a sealant or caulking for your tiles or tubs), then you may notice that over time it becomes yellow following exposure to light and humidity.
Both UltraClean™ and VeriClean™ are based on the chemical “siloxane” which is a chemical “cousin” to silicones. Since “like dissolves like” in the chemical world, siloxanes dissolve silicone glues, inks and coatings quickly and easily.
Vinegar – or a combination of baking soda and vinegar – is touted as a safe, 'all-natural' cleaning solution for silicone sealant. However, both approaches risk damaging the sealant and exacerbating the problem.
Heat. Silicone can withstand temperatures up to 250°C (480°F). But prolonged use of heat can make silicone more susceptible to denaturation and discoloration.
