When sanding or power carving the dust that accumulates in the detail I’ve have done or just clings to the work need to come off as I go. I have used all kinds of brushes, and most were ok. But a few years ago, I was at a the 5 & Dime. And yes, we still have a 5 & Dime for those of you old enough to remember the term. For those who do not know the term it was an early Dollar store. I saw and got a small shoe brush. It has been the best brush I have use for cleaning of carvings with that find dust. The soft bristle gets deep into the detail and will not hurt the work. For cleaning up tags and small pieces the require a stiffer bristle I use a denture brush. Its two sets of bristles, one pointed and one flat, are nice and do not hurt the work.
