Red gunk on lockswitch? (TE Fightstick)

Anyone have an efficient way of getting it off? I tried just scraping and its not really doing much good.

I just used needle nose pliers and pulled them off

It’s usually brittle so it can be flicked off in one piece. Use the edge of a knife, screwdriver, or other flat/pointed object.

Surely by definition a brittle material would fracture easily, meaning you can;t pull it off in one piece.

Sorry - meant ‘brittle’ as in peanut brittle. Hard and simply removed when dry with a flick of the wrist, but becomes glutinous when heated.

Not ‘brittle’ as in bakelite. Apologies for the confusion.
