Foil kinda works for a fine abrasive. Not messy anyhow. I used to use it on my spokes as a kid. I think the way it holds shape allows a softer grip too. It may be an decent arthritic alternative to fine wools.
Worth a shot to see if you like it.
Just a few years ago I sold a blue 40s JC Higgins batwing headlight/battery "gas" tank / rocket nozzle luggage rack, 1/4 skirts w/louvers, etc. All original but 3 links of skiptooth chain. When I brave another try at a ride today it's on a metallic brown Raleigh 20 Folder, chrome fenders, aluminum rack, rectangle mirrors, speedo(kmh), removeable batt.op, lantern style lamp, w/visor swinging handle, and a 2cnd swan neck headight & small tailight on the 6v generator. It looks like it belongs in Quadrophenia with all the chome up front. It holds it own next to a Crate or Murry chopper.
I have another folder. A nice.aluminum Micro I once imagined might be taken along on travels on public transportation; in the case it's like a fat umbrella with a wheel at the bottom. Injuries will likely prevent those rail rides, to ride, from ever happening though... So you'd better do it for me
