I found this plastic cleaner by Plaskolite at Ace Hardware:



Cheap and works well on acrylic. I later found that Plaskolite is a big acrylic supplier so that makes sense. It's also available on Amazon for a lot less than other cleaners that specifically claim to work on acrylic.

This took the smoky haze caused by cutting wood with insufficient fume extraction (during my earliest test runs) right off my lid window.

I went to Ace Hardware to see if they had this in stock locally. They did not. However, they did have another product specifically designed for plexiglass and acrylic. It is named Plexi Clean and was less than $5. Took it home and tried it on the laser lid. Worked great at cleaning off the accumulation of smoke and tar.
