Yes, bleach degrades silicone over time. While bleach is a popular cleaner for removing surface mold on silicone caulking, exposing silicone to harsh or concentrated bleach frequently will break down its chemical structure.
Bleach temporarily whitens mold and cleans surface stains on silicone, but it is highly caustic. Over time, repeated bleach use can break down the polymer chains, causing silicone to dry out, lose flexibility, become brittle, and crack. Furthermore, bleach only hides mold on the surface without killing the roots.
Clean silicone gently by soaking it in hot, soapy water or boiling it for 10–15 minutes. Scrub with a non-abrasive sponge, then use a baking soda paste for sticky residue or a 1:1 vinegar solution to remove trapped odors. Never use bleach or harsh chemical solvents.

Yes, you can use bleach on silicone, but it must be done carefully. While bleach effectively removes surface stains and mold, overuse can degrade, dry out, or crack the silicone over time.
Yes, regular Dawn dish soap is generally safe for silicone products, as long as you use a gentle formula and rinse thoroughly. It is highly effective at cutting through stubborn grease.
Standard 3% hydrogen peroxide will generally not damage silicone if used for short periods, making it an excellent cleaner for removing stains and mold. However, prolonged or repeated soaking can degrade silicone over time, leading to swelling, a breakdown of material flexibility, and reduced lifespan.
Windex chemically reacts with silicone forming a film on it where it touches and by spraying a little on your fingers or a tool (keeping it somewhat wet) the silicone won't stick to you or the tool. Allowing you to manipulate it (spread it, push it, etc...) in ways you normally couldn't.
Yes, WD-40 is an excellent and highly effective tool for removing old silicone caulk and residue. It works by penetrating and loosening the silicone, allowing you to easily scrape it away from surfaces like tile, glass, and bathtubs.
Cleaning up 100% silicone depends on whether it is still wet (uncured) or already dried and hardened.
You can use rubbing alcohol (isopropyl alcohol) on silicone, but only occasionally and in low concentrations (70%). Frequent or high-strength alcohol can dry out, weaken, or degrade silicone over time.
Alcohol based cleaners should not be used for cleaning surfaces as alcohol inhibits the cure of silicones. Soaps or detergents used to clean the surface must be rinsed away thoroughly with clean water to ensure that all traces of the soaps are removed before sealing.
Cleaning Chemicals: Using harsh cleaners, particularly bleach or ammonia-based products, can actually cause silicone caulk to yellow. While these products are great at killing mold and mildew, they also react with the silicone, accelerating discoloration.
What chemicals damage silicone? 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.
Vinegar is the better and safer choice for most mold situations.
Yes, isopropyl (rubbing) alcohol is highly effective for removing uncured silicone and leftover silicone residue. It weakens the bonds of the silicone, making it easy to scrape or wipe away without damaging the underlying surface.
Silicone spray is generally much better for long-term lubrication and protecting rubber or plastic. Original WD-40 is not a true lubricant; it is primarily a solvent and water-displacement agent used for cleaning, freeing rusted parts, and dissolving grease.
We prefer to use unscented detergent and soap when cleaning silicone. You can also place your Souper Cubes in the dishwasher alongside your everyday dishes. For lingering smells or stains, baking soda, hydrogen peroxide, or your oven are all powerful enough to do the trick.
Yes, regular Dawn dish soap is generally safe for silicone products, as long as you use a gentle formula and rinse thoroughly. It is highly effective at cutting through stubborn grease.
Standard 3% hydrogen peroxide will generally not damage silicone if used for short periods, making it an excellent cleaner for removing stains and mold. However, prolonged or repeated soaking can degrade silicone over time, leading to swelling, a breakdown of material flexibility, and reduced lifespan.
Spray Soapy Water: Before smoothing the sealant, spray a light mist of soapy water over the sealant bead. This will prevent the sealant from sticking to your smoothing tool or finger and allow for a smoother finish.
There are several ways to clean silicone sealant in your bathroom. But which way is best? Vinegar – or a combination of baking soda and vinegar – is touted as a safe, 'all-natural' cleaning solution for silicone sealant.
Hydrogen peroxide is no longer recommended for cleaning cuts, scrapes, and open wounds. While it kills bacteria, it is not specific and also destroys healthy skin cells and tissue essential for healing. Additionally, it should not be used for acne, as it can dry out and irritate the skin.
To make silicone clear again, the best approach depends on whether it is stained and cloudy (from grime or hard water) or irreversibly yellowed (from UV degradation). Use baking soda or hydrogen peroxide for stains and a water/bleach soak for mold.
