I wax my own legs at home, using hard wax, and I'm curious as to what the best way is to strain the hair out of the used strips of wax. Since this is no longer approved practice in salons, I can't find any instructions. I'm hoping someone who remembers the bad old days when all the salons reused their wax on multiple clients will tell me how it was done. In particular, what kind of strainer works best? Thanks!
