I found this useful for getting in to those tight corners when polishing aluminium.
I started using an old toothbrush and the head snapped off, which left a nice angle on the shaft so glued a piece of dense foam on to it and then used an aluminium polish / paste to get in to those awkward corners.
Not the neatest of jobs so will make a better one later.
