After a disastrous fire, destroyed my workshop, I salvaged all my homemade tools and pottery from the runes. To return them to the former glory, I use a variety of methods from vinegar to evaporate. To help remove some of the surface rust and soot, I use an ultrasonic cleaner and a vibratory tumbler. Clean up the pottery was as simple as firing it again to burn off the soot. With just a few hours of labor, I also get everything back to the former glory.
