I have a Sankei TCR-S90 that I want to change belts on and clean the potentiometers, but unfortunately, either the the previous owner or the factory clogged up two screw holes with something similar to floral sponge. After all these years, it became rock solid and stuck to the screws. Because the holes are so deep and narrow, I can't do much to remove it. I tried grabbing the screws with tweezers or spraying some WD-40 inside, but it did nothing.

how deep of a hole is it , before you hit the screw head ? .. i would consider drilling them out ... just nibble away on the screw head until you can get the cover off... then once the cover is off , use pliers to unscrew the remaining screw thread ... you can get more screws from the hardware shop or Amazon ... if you go too deep and drill trough the housing , use epoxy or thermoplastic to repair from the inside ... that way, cosmetically it will look untouched
I agree, wasps fill the holes with a tan sand like mixture that dries hard. But if you use an awl or pick, you can usually clean it out. Even if you clean it out, the mix can still foul the Phillips head grooves enough that a screwdriver tip won’t bite but if you use an awl or pick with a fine tip, even those can be cleaned up enough to get driver to bite again.
