Laser Cut Burn Marks on Acrylic

Hi, I have tried to laser cut 1/16" acrylic and the edges have some burn marks. I left the paper on when laser cutting. Some areas cut cleanly and at some places the laser cutter didn't cut all the way through. If I increase the power, I just end up with more burn marks. Is there anyone that can help me or have any suggestions on how to clean the burn marks left on the acrylic? Thanks! :)

Raise the power, cut with chipboard on top. Expensive, but it works sometimes.

a wipe with acetone on a clean terrycloth rag should do it. If it is really bad you may need to sand lightly. If so, you need to you can take a propane or tri-fuel torch and use it to flame-polish the edges.
