However, even the best silicone caulk can turn yellow over time due to moisture, cleaning chemicals, and light exposure. To keep your shower looking its best, choose a high-quality, mold-resistant silicone caulk, clean it gently, and make sure your bathroom is well-ventilated.
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.
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.
Normal clear silicone products will not turn yellow even after being put for several years. But sometimes, during the silicone production process, some clear silicone products that have just come out of the oven turn yellow.
Some silicones, especially in construction sites, have showed a tendency to turn yellow even before the job has been handed over to the owners. This is directly related to the technology used in neutral cure silicones. All neutral cure silicones will yellow due to oxidation of one of the raw materials.

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.
BT1 is a universal adhesive created with bathroom sealant applications in mind. Unlike most other bathroom sealants, BT1 will NEVER turn yellow over time.
Most clear phone cases are silicone, a polymer that can is affordable to produce and provides excellent flexibility. Unfortunately, the downside of silicone is that it naturally turns yellow with age. Excessive exposure to certain chemicals, light, and heat can speed up discoloration.
Iron in the water.
Your household water supply might contain high levels of iron, which combine with leftover soap scum to form a rusty orange deposit on plumbing fixtures, tubs and sinks.
Mix equal parts bleach and water. Dip an old toothbrush or equivalent soft-bristled brush into the mix. Use this to scrub the sole of your shoe, paying particular attention to the yellowed areas. Rinse thoroughly with running water.
White vinegar: White vinegar is a natural cleaning agent that can remove stains from your phone case. Mix equal parts of white vinegar and water and apply the mixture to the yellowed areas of your phone case. Keep it for some time, then rinse it with water and dry it with a cloth.
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.
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.
Boiling helps to quickly expand the silicone pores, releasing trapped odours. At the same time, baking soda and vinegar paste can neutralise odours through a chemical reaction. These methods are fast and effective for routine freshening up of your silicone tableware.
Only a few common materials, such as concentrated sulfuric acid, hydrofluoric acid, and high pressure steam, can damage silicone. Be cautious when exposing silicone to these chemicals.
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.
You need to sprinkle a small amount of baking soda on the case. Using a wet toothbrush, scrub the exterior and interior gently. Once done, rinse the case and dry it with a soft cloth. Let it aid dry before using it on your phone.
Diluted Bleach: For white silicone items, a diluted bleach solution (1:10 with water) can help remove stubborn discoloration. Rinse thoroughly after treatment. Mold and Mildew: In humid environments, silicone items can become susceptible to mold and mildew growth.
Here's why: Moisture and Humidity: Showers are high-humidity environments, and constant exposure to water and steam can trap organic particles, which then become embedded in the caulk. This can lead to a yellowish tint, as moisture combined with heat can cause the silicone to absorb some environmental discoloration.
Rub a paste of white vinegar and baking soda into mouldy areas. Scrub at heavy stains with a stiff-bristled brush or reapply the paste. Rinse with a cold, wet sponge and dry with a microfibre cloth. Spray any mould on bathroom sealant with bleach and water to kill mould spores.
Silicone and silicone-blend caulks are most commonly used for kitchen and bath caulk projects. They are the best kind of caulk for showers, bathtubs and sinks.
