My key cap cleaning process is an ultrasonic cleaner with a little dish soap, then if I want to speed up the drying process they get thrown in a dehydrator at 140° F (60° C). Otherwise air drying on a towel is perfectly fine if time isn’t an issue.

edit: removed redundant phrase

I don’t get this argument, a new Dualsense is $75 with potentiometer sticks that will drift, replacement Hall effect sticks are about $15. So for $90 you can get a Dualsense with Hall effect sticks that you have to solder so you run the risk of bricking the controller. For $9 more you get the Steam controller with all the extra buttons and customizability with Steam Input and TMR sticks out of the box.
