Has anyone actually found a brand that doesn’t yellow over time? That’s my only gripe with the stuff.
I totally get what you mean about the yellowing. I used GE silicone in my shower last fall—looked perfect at first, but now there’s this weird off-white tint around the edges. Not super noticeable unless you’re up close, but it bugs me. I’ve heard some folks swear by DAP, but honestly, I haven’t seen a huge difference. Maybe it’s just something we have to live with for now? The “green” caulk sounded promising, but if it peels that quick, I’m out.
Yeah, the yellowing drives me nuts too. I tried switching to a “low VOC” caulk last year thinking it’d stay cleaner, but honestly, it still faded after a few months. At least you’re not alone—seems like none of them are perfect yet. Just gotta pick your battles, I guess.

You nailed it there. Even the pricier “mold-resistant” caulks will yellow or crack eventually, especially in a bathroom with a lot of steam. I’ve found that keeping a fan running and wiping things down helps a bit, but honestly, some maintenance is just part of the deal. Don’t let it get you down—sounds like you’re doing everything right.
Ever tried using silicone caulk instead of the “mold-resistant” stuff? I’ve had mixed results—sometimes it holds up, sometimes not. Wondering if the humidity in your bathroom is just too much, or if it’s more about the brand you pick.

I’ve gone down that rabbit hole a few times. Here’s what I’ve noticed: pure silicone caulk is technically mold-resistant by nature, but not all brands are created equal. Some of the cheaper tubes just don’t seem to cure right, or they yellow and get gunky faster. Humidity definitely plays a role, but prep is huge too—if there’s even a hint of old caulk or soap scum left, nothing sticks for long.
What’s worked best for me is this step-by-step:
1. Strip every bit of old caulk (razor scraper + mineral spirits for stubborn spots).
2. Wipe down with rubbing alcohol and let it dry out overnight if possible.
3. Use a high-quality 100% silicone (GE or DAP have been solid for me).
4. Run a fan or dehumidifier for a day or two after applying.
I’ve had way fewer issues since I started being obsessive about prep. Still, some bathrooms are just more prone to mold no matter what you do... but good caulk and dry time help a ton.
