Tip of the day: This applies to everyone that restores shoes. Remember we are dealing with peoples feet. If your using the same rags and tools on a bunch of different peoples shoes. Thats not very safe or clean. Just to let my customers and future customers know. I sterilize all my tools, rags and also use brand new rags on every different pair. I recommend that either you buy new rags and sterilize your tools. If your going do something right, do it the right way.
