Yeah particles are bad, but it goes even further than that, the fibers alone in the cloth are abrasive and never fully clean generally speaking either, so any contact invariably causes at least some scratching, even if you cant see it. This is an application where being a clean freak is actually a bit of a detriment more often than not. ‘Clean’ is a relative term. You dont want to micromanage lenses on lasers, they just need to be clean enough to perform. The more you clean it, the worse it gets, as its just going to get dirty again, and the rougher surface is going to degrade performance further as well as hold onto particles even better. If it does its job, then leave it be.
