@pippins_mcgee1 this is my profesional cleaning set,i use topol 2, and acetone
I used that, too, when I worked with Trumpf laser. Still have a bottle of Topol, but it’s too old, and teh lens holder too big for K40 lenses…
Use this every day on the TruLaser 3030 I run at work. Apparently Trumpf now don’t recommend using too much acetone.
They changed politics,now in cleaning set is isopropynol not aceton
Ah! Wasn’t aware of that, thanks. I had the day off last time it was serviced so never got chance to speak to the engineer lol
