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.
