<p>Hey folks,<br> I have quite a few lenses that I am fixing up and cleaning.<br> I am happy with my tools and repair methods for assembly and disassembly.<br> However I am looking on advice as to what the best glass / optics cleaning equipment is.<br> I have a microfiber cloth which is a little dirty, can it be washed?<br> I would probably rather buy a new one or even a couple of cloths, if so which are best and where from for the UK.<br> Also what is the best solution to use, ideally a professional good quality one.<br> Ant help appreciated or info on anyone who clean inside lens and the techniques they use to create a good dust free result., I am also worried about leaving smears or cleaning marks / scratches on lenses.</p>
