Binoculars Prismatic No5 repair

[Peter Laidler]

Can I respectfully suggest that instead of lint free cloth or ANY cloth, you use the cheapest paper kitchen towels you can. These don't(?) contain any of the usual chemicals that the super-dooper expensive and all singing and dancing towels contain. They're also as lint/debris free as it's possible to get. The good part is that because they're so cheap you can simply tear-off and use as many as you like. I have been known to use half a roll doing a pair or No2 binos or a telescope.

I also basically clean down the optics on the bench with cheap industrial grade methylated spirit and then before assembly wipe clean with pure M.S which leaves an absolute surface.
