An idle enquiry

I wash mine regularly with no adverse effects. I do the cloths by hand but don't use fabric softener. I hate having specs on my specks so am forever cleaning them too!

I got a little bottle of cleaner from my optician, and I can get it refilled for free when it runs out

I use the free bottle of stuff with the cloth. Never thought about washing them - I have acquired a fair few!

I have several cloths and they are washed regularly as they pick up all the muck and grease from your specs.

I rinse my specs under the tap with a wee drop of fairy liquid ,it keeps them clean far longer than anything else .If I'm out I use wipes that I get from Boots opticians department .I tend not to use cloths as I think they trap the dirt and spread it .

Thanks. I've got an 'anti mist' spray from the opticians. (It's not all that effective in stopping my glasses steaming up when I'm wearing a mask) I'll wash the little cloth too.

On the few occasions I clean any of my glasses, it's a quick huff and a rub on the bottom of my shirt. Sometimes they get a wash under the tap with fairy liquid, and then dried on the kitchen towel. Never use the bit of cloth in the case.

Be careful wth the water and fairy liquid, it ruined a pair of my glasses that I'd had coated with anti glare.

I’ve got several glasses cleaning clothes which I just bung in the washing machine with other washing

Another under the tap with washing up liquid here.

A lint free lens cloth, and I huff on the glasses. It gets washed monthly.
Keep the cloth sealed in a clear ziplock bag in my handbag.

I use Zeiss Lens Wipes which are individually wrapped and useful to keep in my pocket or handbags.

I put my glasses cleaning cloths in the washing machine. They all still work.

I use Lens Bright from my optician it keeps them clear all day as long as I'm not wearing a mask.

Once again I feel rather small and inferior.....I’ve long ago,lost any of those cloths and would never think to wash them! I use windowlene spray on my specs sometimes and possibly kitchen towel.I am in awe of people’s organisation

Household window cleaner, buffed with glass microfibre cloth

I wash my glasses in warm soapy water (in the shower sometimes)* and dry them with a microfibre window cloth. That's all specs cleaning cloths are in effect.

*When they need it. Most of the time I just wipe dust and smudges off with my T-shirt. Soft cotton won

Soft cotton doesn't do any harm.

yes, me too, under the tap and a smidgen of washing up liquid

I have a microfibre cloth in a clear plastic case. I don't know where it came from but it does a perfect job, even though I haven't washed it. It has a pattern of what appear to be Smarties!
