There are many ways to to clean a dial but once the hands are on and you are doing you "30 Second" examination, nothing beats being able to gently brush away any dust or debris that was prviously unseen without risking damage to the hands.
Users of Rodico will know that it is great for cleaning dial but sometimes the hands are just too small and to easily damaged to risk using anything but a very soft brush.
These tools have a retractable brush at one end. At the other there is soft cleaning pads - one round and one triangular - that allow for a little more robust cleaning in awkward places.
A "must have" tool for the hobbyist and professional alike.
