i use 600grit paper and then IPA or acetone.
Steel wool works too, various scotch-brite products as well, as do
these abrasive pads. But the solvent cleaning is a must.
I had trouble with paint thinner, but it might have been a contaminated
bottle (e.g. greasy rag -- TIP: mount a small outlet (2mm) on the
can/bottle lid.
(cutoff bike valves are great 'cause they have a rubber cap). when wetting
a rag now nothing can get back into the bottle (drip on the rag)).
