This is the one I bought
Scraping Tool | Super Scraper | Carbide Processors
Just lay it on the aluminium surface and pull towards yourself, it lifts out any gasket, then finish with a solvent or if fine polishing is required a silicon carbide sponge of 3000 or 4000 grit can make it shiny as a mirror. A soft brass brush is also a good tool to finish off as it doesnt change the surface characteristics of the item being worked on.
Of course proper common sense is required when using.
Before this I used to use smashed copper pipe to act like a scraper, its soft, but takes longer. In half cases I still have to use the copper pipes - when the area is very small
