Removing Contact Paper From GlowForge Materials

@PrintToLaser has recommended pulling the masking first, then soaking in alcohol several times. You might try that

Is Mass Production of Lasered Products Viable?

I would soak like 15 pieces at a time for a few minutes in alcohol, and the smoke stain would wipe right off with a rag. The material was proofgrade maple, and soaking in alcohol had no affect on the material.

Test "3D Engrave"

Ver nice detailed work! Aren’t these machines great?! With the first few engraves I cleaned with water, I noticed a slight raising of the grain. A while back Dan mentioned alcohol won’t do that, and ever since that is what I have used.

I would drop 15 of them into alcohol and let them soak a few minutes before removing them one at a time an wiping them…

Isopropyl for cleaning wood

I have used both without any noticeable difference, except maybe how quickly the smoke residue softens. Soaking 15 - 20 tokens for about 2 minutes softens the stain where in rubs off easily, by the time I get to the last one it has been soaking for about 10 minutes, and the stain is just laying on the surface and instantly wipes off.

Removing smoke residue from Proofgrade

On a previous order for a thousand tokens engraved both sides using proofgrade medium maple, I found that pulling the mask before engraving and cleaning with an alcohol soak for a few minutes and rubbing with a rag was far faster than weeding both sides of 1,000 pieces. Well, that customer returned and wants 3,000!! As a result I found myself looking to streamline the process. I just discovered that household ammonia cuts that stuff all but instantly, no soak - just a wipe! …
