contact cleaner is usually sold as a can of aerosol-spray.

I seek it in swab/wipe form, preferably in unit-pack. Lots of
alcohol-water pads out there, I don't want to put water on my
equipment. Anyway, it takes the real solvents (eg, hexane) to get
the bad crap off. I'd settle for acetone swabs, I suppose.

Who sells the stuff? URLs, snail-mail contact info?
