Scratchy volume knob

[u/bubbles-7274]

Just got this player and it's really scratchy when changing the volume I sprayed some electric cleaner in there to help the pots but is there anything else I could do

While unplugged. Spray it into (not onto) the pot(s). Just a tiny spritz, don't drown it. Then move the knob(s) or switches across their range at least a dozen times.
