Removing ground

As an alternative to turpentine / methylated spirits for removing grounds, some block outs, and adhesives in general, I use a citrus based solvent called De-Solv-it. It comes in a spray container. You spray it on (outside or in a well ventilated area), leave it a minute, and wipe it off with a dry rag and no effort.

This is an Australian made product and you can get it at most hardware shops. If you live elsewhere around the world, just ask for a citrus based solvent. They work well, are less carcinogenic, are less likely to kill the nerve cells in the tips of your fingers, and don't stink as much!
