PSA: Don't wash your alps switch sense plates in hydrogen peroxide

[Wingklip]

For some reason they seem to corrode in some fashion that prevents them from registering actuation anymore once this is done. I think they corroded through the underside of the gold plating because of the metal used. This is from a keyboard with what seems to be either acid or base corrosives spilled into the guts of it, then somehow through the process of galvanic corrosion destroyed a lot of circuitry and some switches.

Rip alps oranges from some apple m0116 xd

Don't wash your worn sliders with bleach, they will fell even worst.

At least you could salvage the tactile leaves, sliders and top housings to put into some (subjectively) lesser switch.

Hydrogen peroxide makes metal oxidise quicker. I have used it in a recipe to quick-rust steel.

You did WHAT? xD

Just don't wash the sliders at all, just wipe them off with a dry rag. I use coffee filters.
