The anodising is rock hard... unless you take coarse abrasives to it, you won't be removing it any time soon! Strong alloy wheel cleaners could stain anodising if left in contact with it for too long, so always check the label to see the maximum exposure time.

Soup will kill rubber seals and components rather quickly, if left in contact with them for a long time, but it's still a very effective cleaner. It's not exactly environmentally friendly though!
