Recently I wanted to clean up some lubricant on some keyboard switches. On some forums, an Isopropyl alcohol bath was recommended so I decided to give that a try and went to purchase some 91% Isopropyl from Target(purest I could find near me and I admit, I am a little impatient).
Good news - it worked in getting the lubricant off the switch! Bad news, on some of the switches, it left this white haze.
I'm not sure what it is, though from what I've been reading, it sounds like this is a common issue when using Isopropyl, my best guess is that it's some mix of the lubricant mixing with the alcohol and reacting poorly with the switch housing plastic given that I'm only seeing this haze on the bottom half of the switches which were the only parts of the housing that were lubed, the other parts are clean. Another reason for my guess is that this haze isn't appearing in the same amounts on all the switches if at all, some switch bottoms are basically clear.
It does appear to scrape off but looks like it will require a fairly strong brush which I don't have at the moment and I'm not sure if there's one available for purchase that could be used in this situation.
Is there any plastic-friendly household cleaner available that might be able to help speed up the process?
