Cleaning nail art brushes is a pain in the butt but it is a necessary evil for keeping all of your tools in very good condition. I have found that sometimes, a simple cleaning with nail polish doesn’t always do the trick. I’ll end up with pigment still left in the brush. What I d is I swirl my brushes into a drop of clear coat. I always end up with tons of old bottles of goopy, old top and base coats and this is a great way to put them to use instead of throwing them out.
