Solution: Look for high-quality silicone caulk labeled “mold-resistant” or “bathroom caulk.” These products are more resistant to yellowing, and regular gentle cleaning with mild soap and water can help maintain their color.
White caulk turns yellow from UV light. Its just one of those things. If the spot has lots of exposure to light its going to happen. Some caulk brands are better than others.
Getting it White
You can use either a small cup of vinegar or a paste of 1-part water to 1-part baking soda.

“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 should get rid of the yellow color.”
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.
Place the plastic pieces under the sun and leave them there for at least a day. It's the UV rays from the sun that in combination with the hydrogen peroxyde will make yellowed plastic white again.

Like WD-40, vinegar won't magically dissolve silicone caulk. However, vinegar will loosen up particularly stubborn caulk if you don't have a commercial caulk remover in your supply closet. Vinegar can also be used to clean and disinfect gaps after you've pulled out all of the old silicone caulk residue.
The Solution:
Because it takes up relatively little surface space in the bathroom, caulk might not take highest priority on the bathroom cleaning schedule. To keep it from yellowing, cracking, or becoming a new home for mold and mildew, it needs to be wiped down regularly.
Fill a large bucket or basin with warm water. Add one cup of distilled white vinegar to the water and mix well. Place the yellowed garments into the solution and let them soak for 3-4 hours. After soaking, rinse the clothes with cold water and wash them as usual.
Heat: Exposure to heat can also accelerate the degradation of silicone and cause the case to turn yellow. Dirt and grime: Dirt and grime can also build up on a clear phone case and cause it to look yellow.
