When engraving wood with a laser, a brown, maple syrup like residue will deposit on the surface of the
wood. This is normal and impossible to eliminate by POWER, SPEED, or PPI changes. More residue
will be present when engraving deeper and/or slower. This residue washes off with water and a sponge.
We recommend using a kitchen sponge with a nylon string mesh wrapped around it. Dampen the sponge
and wipe off the residue. A damp chamois cloth works well also. Do not use paper towels or a regular
sponge because these materials will get lodged in the engraved area when wiping and are extremely
difficult to remove. A method to avoid cleanup is to mask the wood with transfer tape and peel off the
tape after engraving. If desired, after engraving and before peeling off the tape, spray paint can be
applied to color fill the engraved areas. After the paint dries, peel off the tape. If an intricate drawing has
been engraved and there are many small pieces of tape to remove, it may be easier to flood the masking,
after engraving, with water. This will loosen the tape and it can be easily removed by rubbing it off by
hand. In the vector cutting example, the wood was elevated from the table to let smoke and heat escape
from underneath. If you elevate the wood, mask and/or dampen the bottom side of the wood very lightly,
in which the water acts as a heat sink to prevent the underside from flaming and charring.
