I generally never use an aerosol can for cleaning pots/switch contacts..
not
just because it's extremely wasteful, but because the area needing
cleaning
usually only needs about 2 drops of DeoxIt.
Applying a flood of cleaner product doesn't get the parts any cleaner, it
just makes a huge mess.
Flooding shafted pots typically rinses away the thick grease in the shaft
bushing and a pot will lose that smooth resistance to turning feel that it
had/should have.

It seems that many people just can't resist the instantaneous push-button
solution for a problem, no matter how much the miracle product costs.
With a push-button cure, many appreciate the instant gratification.

A 5oz (weight) can of DeoxIt lasts a very long time when used sparingly.

I buy the areosol versions of DeoxIt, but I spray the liquids into small
poly bottles which have needle tips (syringes don't work since the rubber
pistons deteriorate/swell from contact with the solvents).

The types of bottles I use are the little retail bottles for dispensing a
drop (foot antifungal or eyedrops products), and I add needle tips to
them.
There are small bottles marketed as fishing products for injecting air
into
worms so they don't sink, which are supplied with a needle. To prevent
getting cut/jabbed by the sharp point, the needle can be pulled out and
turned around so the point isn't sticking out.

The paste/grease DeoxIt products can be applied with a toothpick or longer
swab stick, although they are handled easily with a syringe fitted with a
large gauge needle (the rubber piston still deteriorates, but the grease
won't leak out like liquid does).

MM Electronics MP175 16 channel mixer , probably the bee's knees in its
time
1978.
Minor electronic problem , as only 741s , no great problem.
Also one pot needs replacing but all the pots slider and rotary are
dirty/scratchy and I begrudge wasting 2 aerosol cans on this item -
suggestions?






For these sorts of situations I make a reducer of sorts from various sizes
of sleeving down to a short length of PTFE 1mm spaghetti tube, great for
getting into switch and pot bodies, Now just to find some naptha and see if
it is too viscous to go down 1mm minus wall thickness
