I found these cloths years ago, and they clean extremely well and go a long time before needing to wash them. Then I’ll just throw them in the laundry with my clothes, take them out and air dry instead of throwing in the dryer.
If I my glasses end up getting particularly dirty, like grease spots from cooking, I do the dawn dish soap method and dry them with one of those cloths.
It’s like they all watched House of Cards and were like, “Waiiiit a minute… We could do that!”
