Muriatic acid (hydrochloric acid) can remove chrome from brass but would probably unduly roughen an aluminum base. Mix muriatic acid (available at DIY stores, at least here in the U.S.) at a ratio of 1:3 (1 part acid 3 parts water) in a plastic container deep enough to submerge the item to be stripped. The water should be warm but not hot and even then, use it only...

The water should be warm but not hot and even then, use it only outdoors or a well ventilated place. Leave the item in the mixture until the chrome softens and begins to peel. You can strengthen the ratio if needed.

(Use all appropriate precautions in using any acid!)

The chrome is applied by electromagnetic processes and often involves the electroplating of nickel or other metallic surfaces, to wit; you won't be able to remove. At least not by yourself since removal of nickel is involved and uses chemical that aren't normally available...
Oh... one other precaution... don't spill any of the acid mixture on a cement floor. While muriatic acid is often used to clean cement floors, used at too strong of a mixture actually removes the protective outer layer of the cement floor and can ruin it...
