AND it reacts with aluminum to create hydrogen!

yes, don't fuck around with corrosive chemicals. Strong acids or bases will destroy tissues with ease, especially if they're not protected by skin (which also gets dissolved but more slowly)

A super thin layer of food safe oil. Apply it, Buff it back off as much as possible than wash the pan.

If it's cast iron you can just re-season it.

We're doing our best guys, trust us

They should make tiny stovetop Roombas that look like the robots from Batteries Not Included

Fair point, but this is one of those "if a jobs worth doing, it's worth doing badly" situations where just waving a towel at it still helps prevent stuff getting out of hand.

Of course this is easiest with induction because you don't need to wait for stuff to cool at all

Depends on the hardness of the metal you would need a metal. ~~These stoves are mostly aluminium oxide, which has a mohs hardness of 9 and steel is 4-8.~~ I looked more into it and I found glass ceramic stoves have a mohs hardness of 6-7. So a very hard steel should be able to scratch it, but most steels including stainless should be fine.

Glass is harder than most metals.

It can, yeah. You have to be careful to press gently in the center of the blade and not put pressure on the corners which will gouge huge scratches into glass. I have one of these for cleaning my paint pallette and get double-duty out of it on oven cleaning day.

They make cleaning kits for these stove tops that typically come with a cheaper plastic version of the tool with a weaker metal razor. Still does the job well, but less scratching chance. Also usually comes with a fine-grain polishing cream and sponges to apply it with. The cream helps to buff out lighter scratches and remove some of the cooked on stuff.

It doesn't scratch the glass, even when applying quite some force. The blade dulls pretty fast, it probably doesn't have the hardness to damage the glass.

It's specifically called a [glass/ceramic] stove cleaning [blade/scraper]. I've used one a lot and it doesn't seem to do noticeable damage (glass stove tops need to be pretty tough anyways to handle regular cooking)

One of these is not like the other

Possibly, though sliding your thumb over the edge pretty fast at an angle seems to end up causing the slice anyway. I regret not taking pictures during the healing process :(

This is what amazon calls that cleaning kit if you want to look for it:
