And acetic acid - household vinegar works- tried and tested by myself several times. The problem is it will also remove the normal metal patina as well, so dipping is not a good idea unless the badge is a basket case anyway .
Last time I treated a patch by applying a droplet to the verdigris only with a kid's paintbrush - might have to dab it on a few times to stop it drying out time it's reacting. The just brush it off with an old toothbrush under running water.
