I've always had a bit of a problem of the laser leaving a smokey edge after cutting laserable plastic and acrylic. I'm sure you've all experience it, and no a lot more about removing it then I do.
I've always been able to remove it to some extent, but requires a fair bit of time and a lot of elbow grease and now that I'm beginning to pick up a lot more work then I was originally it's simply no longer worth my while to spend that long cleaning every little tag/shape/letter etc that I cut. I've come to the conclusion that simply cutting without leaving the residue is not possible.
I want to stray away from the whole leaving the paper backing/masking on everything because I'm also cutting alot of intricate little things 100's of times over and it's also not worth my while peeling it all off afterwards as opposed to peeling it off from the whole sheet. I also can't put that burden on the customer as the customer base we have built from our cnc router was made from supplying everything as a finish product and would like it to continue that way, it's how we keep our customers coming back.
Anyway, I've tried cleaning using a denatured alcohol as well as dish washing liquid, I've given the DNA a flick as the dish washing liquid does a better job, but still not quite what I'm after. Now, I'm at somewhat of a stand still on what to do. I've rang my supplier of my laserable plastic and asked for what they recommend and was told a citric based cleaner, sounded easy to find it was mentioned, however not as easy as I originally thought, anybody have a recommended product?
Thanks in advanced.
