I wanted to thank everyone on the forum who gave the advice to use wet soapy newspaper on glass. This is the first time I engraved glass and I wasn't too pleased with the results. Customer was fine with it, but it was not up to my standards. Luckily, that was a spare the customer gave me so I tried the wet soapy newspaper trick on the final piece (actually I used wet soapy cheap paper towels) and the results were perfect. I just want to tell everyone at this forum how helpful you have been with the thousands of posts over the years. Thank you
