This mini vac is great for those hard to reach places. Won't help with waxing, but will get that unwanted dust and debris from hard to reach places. Combo that with an air compressor to blow out before hand. Sometimes the best way to keep those areas(orbits, etc) nice is to get rid of the debris that causes problems/ball marks in the first place. This along top of always changing balls whenever needed.
