I would make sure you’re not pushing around residue if it leaves contacts duller, 99% IPA shouldn’t leave it’s own residue (unless the dullness is from scratching the pads with the cleaning.)

Vapor method works well enough, but requiring sunny days is a bit of a bummer. I use it sometimes, but submersing in a UV box works pretty well without being too rough.

I honestly don’t run into that with magic eraser, you’re keeping the eraser wet right? I might just be pretty gentle with it, but I’m pretty sensitive to this stuff and haven’t noticed any damage.

Yep go for the direct application stuff, I forget exactly which series it is but is easier to apply. One thing I’ve copied from the YouTuber TronicsFix is applying the deoxit to a small square of magic eraser and using that to clean the contacts.

You can deyellow with retrobright, but the downside is that it makes plastic more brittle. If the plastic is already brittle, there’s not many options that don’t involve melting/warping the plastic. For some stains you can get them out with a magic eraser, it’s essentially a high grit sponge.

Agreed about deoxit, it’s still good for contacts though (cartridges and such.)

I am however now worried if I said anything about Go lol

I think the big issue is that a lot of these aren't discoverable, and because Siri isn't very smart at natural language you won't discover them by asking for something similar like you could with Google Assistant. An LLM for parsing requests could be super interesting here.

I do personally agree that unstandardized batteries are a problem in wireless mice as eventually you'll be unlikely to find an exact replacement, but I think there can be plenty of wins from wireless. No cable drag (annoying!), no cable running across the desk (I can stow my mouse in a drawer in less than a second to clear my desktop), and I don't have to worry about the cable fraying over time (legitimately something that happened with my razer years ago!)
