The only way to help when you have wiper problems is get the
cleaner/lube inside the unit. Spraying down the shaft usually does
not accomplish this.

I recommend Caig labs products such as D5 or pro gold. If the pot has
holes in the back, spray into the holes and turn the pot for a minute
or so to clean off the resistance contact area.

Sealed pots (or switches) are another issue. On the plastic cased
units, i have developed a method of last resort. Take a fine tipped
pencil soldering tip and slowly burn a hole through the back while
working the control back and forth so the internal melted plastic
won't jam the control. Then spray the cleaner in the pot. Sometimes i
reseal with a dab of RTV or such,. Not a 100% fix, but it will bring
some back to life.

Compressed air from Staples. Won't wash anything away - just stirs it
up. Spray sparingly. Then power up device and turn knob back n'
forth until crackling - noise disappears and/or volume or effect gets
louder/clearer.

a neat trick is to wrap a couple of turns of insulated wire around the
control's knob,then pull alternately on the wire ends to rapidly spin the
pot shaft from limit to limit;that can "clean up" a noisy pot fairly
quickly,and it's not hard on the fingers.
