Thank you! It took me decades before I figured out that it doesn't matter how soft the cloth is if all you're doing in scrubbing abrasive dust or dirt around on the lens with it. It isn't always possible, but I try to rinse first to get as much particulate matter off before wiping.

Can you explain why cold water? I've always done it, but only because I once made the mistake of buying photoreactive lenses (and, you know, most of us just have to live with a decision like that for a while), and hot water made them go dark. I didn't think tap water temps would be enough to mechanically stress the material; is the plastic so soft that it could be damaged, or is there another reason?

I generally use a similar method to this to deep clean my glasses, but I often don't want to do that deep of a clean all the time since my glasses get dirty fast. I find the Zeiss glasses wipes work well for me, but there is a lot of waste involved. Oddly enough, their cleaning spray works terribly for me, and it seems to just spread grease around the lenses...

I was looking at the ingredients for each, and it seems that Zeiss used different ingredients for the two products. The wipes contain water, isopropyl alcohol, and "proprietary detergents and preservatives". The cleaning spray contains water, butyl diglycol, and two other ingredients that to my knowledge are just preservatives. I think that in theory I could make a better cleaning spray by getting the right concentration of isopropyl alcohol and distilled water, mimicking the concentration in the wipes. What do you think is the highest percentage of isopropyl alcohol that I could safely use on glasses without damaging coatings?

That's the way I've been taught by the guy who makes my eyeglasses too! I remember being slightly incredulous but took his word for it.

I only touch the lenses while soaping it, making sure that (liquid dish) soap is evenly distributed across the lenses. Then, I rinse them thoroughly in a stream of running water until I can no longer see water spots on their surfaces. I give the eyeglasses a slight tap to dislodge any excess water before wiping it with a dry clean cotton cloth I reserve for that purpose.

Thanks! That looks pretty easy, and it seems to work for a few other posters.

User name checks out.

Thanks for the tip. Just to be clear... are these instructions for cleaning the glasses, or the microfibre cloth?

Hand soap works fine as well.
