Consider what is going on at the stylus and cantilever level. The crud build up is basically just dirt, bits of vinyl (hopefully not much vinyl) and some chemical residue. What is needed to clean it is just some mild detergent solution and a light physical scrub.
I've used a stylus cleaner kit I was given with a Lyra Clavis da Capo and also the Disc Doctor stylus cleaning kit brush and liquid. Both clean the stylus and cantilever quite adequately.
IMO, it is necessary to use a wet brush to actually loosen and remove the build-up on the cantilever and stylus. A Magic Eraser might work OK for the stylus, but there is a minimal benefit for the cantilever. In my opinion.
