So you used an evaporative contact spray like Freon or IPA.
Yes evaporative, but I had to open the switches to apply it.

WD40 works in seconds with no disassembly.
Try some WD40 or similar spray lubricant - seriously bet it makes all
the
switches work again.
I would prefer to replace them as the switch mechanism inside did not
look
very well.
** You have NOTHING to lose by TRYING my suggestion.
Been working near miracles for me, nearly every day, for 40+ years.
How does the WD40 go for pots ?
** If a squirt of WD40 does not restore good operation - nothing else
will.
But be very careful with linear faders as it can dissolve the grease that
gives them a nice feel - if possible, open them up and clean the track and
wipers with a rag and small brush dipped in WD40.
I have always thought it was short term and destructive.
** Nonsense.

DeOxit Red is what I use for rotary pots. Deoxit Gold for switches and
jacks. They make a DeOxit for linear pots, but it often makes things
worse. Use a swab with Lubriplate, after careful diassembly and cleaning.
