I do use a toothbrush on my suit. About every 1/2 dozen dives or so. And wash, dry, and condition the seals after every outing. Sounds like you are using too much wax and it may be a little on the soft side.
There is a beeswax that you can use. It is not the cheap yellow stuff that may have pollen, dirt, bee innards and poop in it. What I have been using is a block of pure pharmaceutical grade beeswax. Got mine at a Fabric and craft store. It is hard, does not gum up, and yet cleans off easily. Been using that on my suits and the zippers on my motorcycle chaps since 2006. Have never had to replace a zipper.
When I bought it the price was $14.00. For a one pound slab. After nearly 7 years of using it, giving some away, and even losing a chunk I still have about 1/2 of it left. Compare that to a tube of "zipper wax" that shops get as much as ten bucks for.
