My blue switch space key gets stuck on its way up. This happened after I used isopropyl alcohol on it to fix key chatter. I think it's best for me to use lube. I know that it would ruin the click but I've heard that low viscosity lubes won't affect it that much and at least it's better than it being stuck. I have confirmed that it's not my spacebar keycap since the problem still occurs with the keycap off. I don't want to solder/desolder anything so I think using lube with a paintbrush would be better. I've heard that I should use krytox gpl 105 as it as low viscosity, are there any cheaper alternatives? And how much grams/millilitres is enough for one appliance and maybe a few other appliances in the future if the problem persists? Thanks!
