Lasered Acrylic Residue

Hello everyone,
I am experimenting with some two-color acrylic from inventables. I’ve noticed that there is a fair amount of rub-off residue on these pieces, especially noticeable on the dark colors (ex. yellow on black acrylic).

I hate to think that someone would have one of the acrylic pins that I cut rub off residue on their clothing :frowning:

What are your best practices for getting rid of this residue?

Thanks in advance!

Best to use some type of masking tape while lasering. And when done, I tend to rinse the piece with or without soap and wipe dry.


Acrylic a nonporous plastic so just wash it with anything that doesn’t damage the acrylic. I’d try dishwashing soap and a soft brush.

As mentioned, masking to prevent the discolor buildup on non engraved areas…
RED (on something) color seemed to be the worst.
I even had to do a very low power additional pass on a few designs to burn off the red residue that blew into the engrave.


I had the issue with black on white 2 color acrylic, and got good results cleaning the engrave with a stream of alcohol from a squirt bottle.

This is a really informative video about two-toned acrylic.


I keep an old toothbrush by the sink, it works great to loosen up those acrylic deposits.
