Step 3 · Apply Heat to Soften Putty
To deal with the stubborn, bonded putty that remains, you'll need to soften it. Use a standard hairdryer on its highest heat setting, or a heat gun on its lowest setting. Hold the heat source about 2-3 inches from the putty and move it continuously in a slow, circular motion around the ring. Do this for a few minutes until the putty becomes visibly softer and slightly glossy. This heat application breaks down the linseed oil in the putty, making it pliable again.
