hello all,
just thought i would post this since i discovered by accident and it really has solved a lot of problems for me!
i have to cut a lot of mdf, ply, paper, card etc. in my laser and these materials tend to leave a nasty 'tar' buildup in various places. ( especially the mdf! )
it can be very hard or near impossible to remove even with various solvents, citrus cleaners etc.
however one day in frustration i began trying various things which were lying about to see if anything would loosen it------
