Snap, crackle, pop

Some preamps will emphasize ticks and pops as well!

Sometimes the loading on the phono cartridge can help too; a lot depends on what cartridge you have and the phono preamp.

I rarely clean records unless they have obvious problems. For the most part I use a dust brush. Ticks and pops are not a problem despite that, although I am careful of the used LPs I buy, and try to take care of them by not handling the playing surfaces, storing them upright, etc.
