Keeping your tongue scraper from becoming a science experiment

Leaving it in a gym bag... yeah, that sounds like the time I left mine in the shower for a week and it basically turned into a petri dish. I usually just rinse mine really well after each use and give it a quick scrub with my toothbrush every few days. I’ve tried boiling a metal one before, but I’d definitely skip that with plastic - mine got all warped and weird. If I’m feeling extra cautious, I’ll hit it with a little mouthwash rinse, but honestly, as long as it’s not growing fuzz, I call it good.

I get the “not growing fuzz” standard, but I’m a bit more paranoid about bacteria than that. Ever tried using a UV sanitizer? I grabbed a cheap one meant for toothbrushes and just stick my metal scraper in there after rinsing. Not sure if it’s overkill or actually effective, but it gives me peace of mind. Curious if anyone’s run into issues with those actually damaging the tool over time?

I get wanting to be extra careful, but honestly, I think a good rinse and dry is usually enough for metal tongue scrapers. UV sanitizers sound cool, but I’ve read mixed things about their actual effectiveness - especially with cheap ones. Plus, some metals can get a bit discolored or dull if they’re exposed to UV light a lot. I had a stainless steel scraper that started looking weird after a few months of using a sanitizer meant for my retainer... not sure if it was the UV or just age, but it definitely didn’t look as shiny.

If you’re really worried, maybe stick with an alcohol wipe every so often? It’s quick and doesn’t seem to mess with the finish. I get the peace of mind thing though - sometimes it’s more about feeling clean than the actual science.

Alcohol wipes are my go-to too - super easy and I don’t have to worry about melting anything (been there, done that, with a mouthguard… yikes). I just leave mine out to dry after. Sometimes I wonder if I’m overthinking it, but hey, better safe than tasting mystery funk.

I get what you mean - sometimes I wonder if I’m being too careful with cleaning stuff like that, but honestly, better to overthink than end up with a gross surprise. Alcohol wipes seem smart. I tried hot water once and it warped my scraper, so... lesson learned. You're definitely not alone in wanting to keep things fresh.

That happened to us too, actually - my kid’s plastic scraper was never the same after a “sterilizing” attempt. I switched to stainless steel for that reason, but now I’m curious: has anyone had issues with metal ones rusting or getting discolored over time? I wipe ours with alcohol, but I still worry about missing something.

I’ve actually had a stainless steel one for a couple years and it’s still in decent shape - no rust, but it did get a weird rainbow tint after I left it soaking in mouthwash overnight. Not sure if that’s a problem or just “character.” Anyone else get that?

That rainbow tint is actually pretty common with stainless steel, especially if it sits in something acidic or with alcohol for a while. I got the same thing after leaving mine in mouthwash too long - looked like some kind of oil slick. From what I’ve read, it’s just a harmless oxidation layer, not rust or anything dangerous. I kinda like the weird colors, honestly… makes it look less like a medical tool and more like a sci-fi prop.

I noticed that rainbow sheen on mine too after I left it soaking in peroxide, trying to “deep clean” it. At first, I freaked out thinking it meant the metal was ruined and I’d have to buy a new one (I’m not trying to replace stuff all the time). But honestly, after rinsing and using it again, everything seemed fine. The colors are weirdly cool, but I do sometimes wonder if I’m just being cheap by not swapping it out. Has anyone actually had theirs start to rust?

That rainbow sheen is actually a thin oxide layer, not rust. Peroxide can accelerate oxidation, especially on stainless steel. In my experience, it’s usually harmless - just cosmetic. I’ve only seen rust if there were already scratches or if the scraper was really cheap metal. As long as there’s no pitting or orange spots, you’re probably fine. I still use mine after similar “science experiments”... no issues so far.

Interesting point - I've seen that rainbow effect too, and yeah, it seemed more like a weird stain than actual rust. But I sometimes wonder if all those “cosmetic” changes could affect hygiene long-term. Like, does the oxide layer make it harder to clean off bacteria? Or am I just overthinking it? I’ve switched to copper scrapers after getting tired of the mystery spots on stainless... anyone notice a difference in how clean they feel?

- That’s a good point about the oxide layer and bacteria. I’ve wondered if those rainbow stains are just ugly or if they actually trap more stuff.

“I’ve switched to copper scrapers after getting tired of the mystery spots on stainless...”

I’ve actually found that the tarnish on copper scrapers doesn’t seem to bother me, but I get what you mean - it looks weird and sometimes feels gritty.

“Does that help keep both stainless and copper looking/felling clean, or am I just making more work for myself?”

I totally relate to the weirdness of tarnish on copper - it’s like, is this thing clean or just “vintage”? I used to go overboard with scrubbing and wiping mine down after every use, but honestly, just a quick rinse and letting it dry seems to do the job. Haven’t had any funky smells or surprise science projects yet. Water spots are annoying, though… I’ve just learned to ignore them unless I’m feeling extra fancy.

I wish I could be that chill about it, but honestly, I get so anxious about any hint of tarnish or weird smell. My brain just jumps straight to “germ city,” even though I know copper is supposed to be antimicrobial. Here’s what I do (probably overkill): after each use, I rinse the scraper under super hot water, then dry it off with a paper towel. Every couple of days, I’ll give it a quick rub with a bit of lemon juice and salt - just to be sure nothing funky is lurking.

Water spots drive me nuts too. Sometimes I’ll stand there buffing it like I’m polishing silverware, which is kind of ridiculous for something that spends two seconds in my mouth every morning. But I had one bad experience where I left it damp and came back to greenish gunk, so now I’m extra careful. Maybe I’m paranoid, but better safe than sorry...

Maybe I’m paranoid, but better safe than sorry...

Honestly, I get it. I used to freak out about any hint of green stuff too. After braces, I got weirdly particular about anything that goes in my mouth. That lemon and salt trick is actually pretty smart - never thought of that. I just rinse with hot water and dry it on a towel, but now you’ve got me wondering if I should step up my game... Water spots are the worst though, they make everything look gross even when it’s clean.

I wouldn’t call it paranoid at all. Anything that goes in your mouth should be as clean as possible. Hot water and a towel’s usually fine, but if you’re seeing buildup or weird colors, a deeper clean like lemon and salt can help. Water spots are just cosmetic, not a sign it’s dirty, but I get why they’re annoying.

Honestly, I geek out a bit on cleaning stuff like this. I started running my stainless tongue scraper through the dishwasher once a week - just toss it in with the silverware. Never had any weird gunk or colors since. Lemon and salt is solid, but if you’re lazy like me, the dishwasher’s a game changer. Water spots bug me too, but yeah, they’re just cosmetic... I’ve given up fighting those.

- Dishwasher trick is clutch - been doing that for my electric razor heads too.
- I’m not patient enough for lemon and salt, honestly.
- Water spots drive me nuts, but after a while I just stopped caring.
- Once tried scrubbing with vinegar… didn’t really help, just made everything smell weird.
- Stainless steel’s tough, so I figure as long as it’s not crusty, it’s good.
