Sticky Keys on Desktop Calculator

Have this old Bond Trader, but several keys on left are sticky, as in if I depress the key there is resistance and it won’t rebound, I have to lift it with a paperclip. Doing know why, no obvious coffee stains but that’s my guess, or CocaCola?

Who knows how to repair sticky keys?

for some keyboards there is a tool with 2 clips coming down from the handle - each clip is squared off and you press down with one clip on each side then pull up to remove the key

or... take off the cover and remove keys to clean

and clean your finger nails !!

Rubbing alcohol.

This

worked on espresso machine project #3 last night - that’s after a bunch of cleaning!

ok, rubbing alcohol

Tell me you didn’t type 5318008, look at it upside down and get all excited...

I'd bet without even looking at it properly you could take that apart and clean behind every key and make it as good as new.
This is one of the many reason I like older vintage stuff like this. It was made to be serviceable.
