Today I cracked out my Mitsumi keyboard for a wee bit for funzies and much to my surprise, realised it's got a fairly respectable 4 key rollover? Typically boards of this age only go up to about 2 or 3? I'd be really happy to use this for a bit, however... the switches...
Oh god the switches...

Now I've had the pleasure of trying out good Mitsumi miniature mechanical switches in the past but these are sluggish and weighty... Back in 2022 I did attempt to remedy their previously scratchy and sluggish state with some 205g0, but I think this may have been a bit thick?
I think originally what they would have needed was a proper clean of any dust, rust and debris inside them, and I do have contact cleaner handy but I would really appreciate further advisory from more experienced mini-mech users
