“Can any type of leather be processed with the laser?”
You can certainly process genuine leather as well as synthetic leather (leatherette) with a laser engraving machine. However, please note that some kinds of synthetic leather contain PVC compounds, which can be very dangerous! Harmful gases are released from PVC, so we must advice against cutting, engraving or marking anything that may contain this harmful substance. You may damage your laser machine or possibly even hurt yourself!
“How do I clean a finished workpiece?”
First, you must differentiate between genuine and synthetic leather.
It is hard to recommend any safe cleaning products for genuine leather – if the product is too aggressive, the material can dry out or even form smudges. So really, we would suggest delicately wiping the product with a clean, dry cloth. If you still wanted to use a cleaning agent of some kind, we would recommend testing your choices on a scrap piece of material first.
Leatherette can be easily cleaned without having to worry about material damage. Just use a damp sponge – the shape will not warp, and the colour will not change!
