Default Re: Degreaser for cigarette tar removal

If you're trying to remove nicotine-stainage from fabric like speaker-grilles, I've foun that Ambersil "Foaming Upholstery Cleaner" [available from car-spares places like Halfords] works well.

Spray it on, watch it foam, leave it for a few minutes, then _gently_ suck over the surface with the nozzle of a wet&dry vacuum-cleaner to drag off the dissolved crud. Be careful though - quite a lot of old speaker-fabric is by now well-rotted by age, and once you remove accumulted decades of dust/grime/nicotine the whole thing can crumble.
