Latex, Silicon Mix 1 teaspoon of a white dishwashing detergent in 1 quart warm water. Sponge the stain with the sudsy water until all is removed. Sponge with clear water to remove all detergent residue. Wipe dry with a soft clean cloth.
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.
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.
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.
Grout sealants, often silicone-based, are designed to protect against stains and moisture. However, the acid in vinegar can break down these sealants, exposing the grout to staining.
Tackling Discoloration in Silicone
Fill a container with hydrogen peroxide. Submerge the discolored silicone item. Let soak for 24 hours.
Apply heat for easier removal
While sealant removers and methylated spirits are often sufficient to remove the silicone sealant, some parts of the silicone may still refuse to budge. To get rid of stubborn sealant, try applying heat using a heat gun or a hair dryer.

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.
Bleach. If the above method doesn't work and there are still stubborn patches of mould on your silicone, you can use a combination of bleach and water. Mix one part bleach to four parts water and spray liberally over the silicone sealant.
For removing silicone from painted surfaces or plastic objects, isopropyl alcohol is a great choice that won't ruin the surface beneath. For other surfaces, you can test toluene and xylene - just always be sure to check it on a small, inconspicuous spot before you apply it everywhere!
It is not indestructible so avoid scrubbing it with abrasive surfaces or using your nails and teeth on your toy. To clean your toy you can wash it with water and a toy friendly soap, which is a soap that does not contain silicone. We recommend Dawn dish soap for this.
Since synthetic silicone rings are polymers, they also will not dissolve from being in contact with isopropyl alcohol. In some cases it will absorb the alcohol temporarily (swell), but once the alcohol evaporates from the ring it will return to its normal size and shape with no damage to the structure.
Use Baking Soda: Occasionally, use a paste of baking soda and water to gently scrub the case with a gentle brush for a couple of minutes. Baking soda is a mild abrasive that can help remove surface stains and slow the yellowing process.
Place the silicone items in a container. Add enough hydrogen peroxide to cover the silicone. Soak overnight. Remove the silicone and rinse with hot water.
The primary culprit behind silicone hose color changes is the absorption of a small amount of nitric oxide during use. Nitric oxides are formed when oxygen, nitrogen, and water vapor coexist. As ozone travels through the silicone tubing it encounters ambient air, which contains nitrogen.
We recommend vinegar, white spirit or a sealant remover such as Unibond or WD-40. Before you begin the application, start by clearing the area you're working in to avoid getting anything dirty or damaged.

Once you have the silicone solvent option of your choice, apply the softening agent thoroughly to all areas of the silicone.
