. . . . it was somewhat dusty in there. I sprayed everything down with contact cleaner and let it dry over night. I just fired it up and...........there's no cracks or pops or flashes, everything's back to normal.
Windex would probably have been a better choice for cleaning.
Many of the modern spray contact cleaners, even after drying, continue to attract dirt.
