Doug We just bought some silicone bands from Sayitbands.com. We are testing our the engraving and we are using the rubber stamp setting on our 30watt ULS system. It engraves great, but we are having a hard time getting rid of the white residue that is left over. Right now we are using Murphy's Oil in water and using a toothbrush to get it out. Most come out but it seems to come back. Any ideas? Thanks Matt Heinzel
