Mirror cleaning

[ps_bond]

I'm finding the rocket blower isn't shifting the dust from the mirror adequately; I assume that a soft lens brush is about the only thing that's safe to use on the mirror?

Just been reading up on the Solus printer by way of comparison; they say they have a quartz optical path. If that means what I think it does, that's a huge chunk of quartz to be using?!

I've been using an eyeglass lens cloth to clean off the mirror before each print.
Granted it's only been a week, but I haven't noticed any issues.
