I’ve actually wondered about this myself because I used to clean my trays with hydrogen peroxide, thinking it’d be extra thorough. My dentist wasn’t thrilled—he said it can degrade the plastic over time and sometimes leaves a weird aftertaste. Switched to just using mild dish soap and a soft brush, and honestly, they’ve held up way better. Never noticed any lingering taste or anything. The fizzy tablets always left a film on mine too... kind of gross. If you’re worried, plain soap’s probably fine—I totally get being paranoid though, those trays aren’t cheap!
I totally get the paranoia about keeping those trays clean—especially when you realize how much you shelled out for them. I used to obsess over mine, too. Funny thing, I also tried hydrogen peroxide at first because it just seemed like the “cleanest” option. But my trays started getting this weird cloudy look after a couple months, and I thought maybe I wasn’t rinsing well enough. Turns out, that stuff’s just too harsh over time.

Same here. I tried those little denture-cleaning tablets thinking they’d be gentle, but my trays always felt slippery and never quite clear afterward. Plus, the smell stuck around, and I could taste it the next time I used them. Not ideal when you’re already putting up with whitening gel flavor.
Dish soap and a soft toothbrush have been my go-to for ages now. I just use the tiniest drop, scrub real quick, and rinse like crazy. Never had any issues with taste or residue after that. Honestly, my trays have lasted way longer since I ditched the “extra” cleaning methods.
One thing I did mess up on—left mine in a hot car once and they warped. Had to cough up for a replacement. So yeah, keeping them clean is one thing, but keeping them out of heat is a whole other lesson I learned the hard way.
If you’re worried about germs, I’ve heard some people use mouthwash for a quick soak, but my dentist said even that can mess with the plastic if you do it too often. It’s wild how something so simple can get complicated fast.
Bottom line—mild soap and water seems to be the sweet spot. Way less drama, and your trays don’t end up tasting like a science experiment.
I totally relate to the hot car mishap—mine warped after just one afternoon at a friend’s barbecue. Lesson learned. Have you ever tried those UV sterilizer boxes for trays? I keep seeing ads but I’m not sure if they’re worth it or just overkill.
I had a tray go soft and lopsided from leaving it in the glovebox one summer—never made that mistake again. As for those UV sterilizer boxes, I’ve seen them everywhere lately but honestly, I just stick with rinsing and the occasional soak in denture cleaner. Feels like overkill to me, unless you’re super germ-conscious or sharing trays (which… ew). Haven’t had any issues doing it the old-fashioned way.

I get where you’re coming from—UV boxes do seem a bit much if you’re not worried about germs. But have you ever noticed any weird smells or stains after a while? I used to just rinse my trays too, but after a few months they started looking cloudy and feeling kind of gross, even with denture cleaner. Maybe it’s just me being picky, but I switched to using a UV box every now and then and it actually made a difference.
I’m not saying everyone needs one, but if you use your trays for months at a time, doesn’t it make sense to go a little further with cleaning? Especially if you’re prone to mouth sores or sensitive gums. Just curious—have you ever had issues with buildup or irritation from the old-school cleaning method? Or maybe your trays just hold up better than mine did...
