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 tried copper for a while and it does feel smoother, but I noticed it tarnishes pretty quick too. Not sure if that’s better or worse for cleanliness.“I’ve switched to copper scrapers after getting tired of the mystery spots on stainless...”
- Has anyone tried just wiping down the scraper with alcohol every so often? Does that help keep both stainless and copper looking/felling clean, or am I just making more work for myself?
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.
Honestly, I tried the alcohol wipe thing for a while, but it felt like overkill. If I rinse right after using it and let it air dry, it’s been fine. No science experiments yet... just the usual battle with water spots.“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.
