K&F CONCEPT 3 Pack Microfiber Cleaning Cloth（15x18cm）, Washable Lens Cleaning Cloth for Cleaning Camera Lenses, Glasses, Screens, Cameras, Eyeglasses, LCD TV Screens, Tablets

Full disclosure - I received this product as a member of the Amazon VINES review program. The comments and opinions are based on my knowledge of similar products and experience using the product listed. I'm always reaching for a cloth or cleaning wipe to get the skin oil off my glasses. I have oily skin and seems like no matter what I try to do to control skin oil from getting on them, I always seem to have it there. I go through a box of pre-moistened glasses cleaning wipes every week seems like. I use these microfiber clothes with a special spray cleaner made especially for cleaning optic and glasses and it really works well. The microfiber cloths won't scratch up your lenses like a paper towel or Kleenex might and worse yet, getting a Kleenex with aloe or such on it then using it on your glasses makes everything worse! The microfiber cloths are lint free, feel like silk, extremely soft and are washable for reuse. The 6 x 7 inch size is plenty big enough for most jobs and can be used from cleaning your glasses, wiping off a phone screen to lightly touching up an expensive camera lens. At this size, a couple of them would easily fit in a purse or hip-pack or one in a pants pocket. I keep them around the house and car because I'm a stickler for clean glasses and hate looking at an oily, dirty phone screen through smudged glasses.

I needed some replacement cleaning cloths for my eye glasses, my husband stole one as as soon as the package came in, so he got first use, but he really likes his. I keep one on my desk, and another in my case in my purse, he keeps his in his truck. I'll grab another package of these, they're nice and gentle, get my lenses clean, and they don't pill or anything when I do wash them. I don't use fabric softners or anything like that on these, just plain detergent, and I've been line drying simply because it's so hot this summer. They dry up quick on the line, either indoors or out, and I've not had any issues with residue or anything else. I wash these with like towels, the smooth kind that don't have a nap, or anything that could pill, hot water, detergent, and that's it. Works great for me.

These are very soft, and very good for wiping dust off screens and sensitive eletronics, or anything you want to keep very clean really. I also like that they are individually wrapped, so you can use 1 or 2, and have 1 super clean and ready to use, whenever you need it. Right now I am using one as a makeshift lens projector cover, so dust does not get on my lens projector. (over time you might get some wierd little stuff stuck on such a screen, which could then show up on the movie as you are watching....very annoying.) So best to use one of these, and protect your screens, and other sensitve items. Very useful, and very happy with the individual wrapped packaging, and good value for a 3 pack to keep an extra 1 or 2 around for whatever/whenever you need.

If you have used a microfiber cloth before these will likely be about the same quality as you would expect. They come with individual clear wrapping which makes them easy to take with you. They are slightly larger than the ones I normally get included with a new pair of glasses (measuring 15cm x 18cm) and are not as soft or silky. However, they got the job done just as well. I tested them with a 32 inch Samsung G7 Odyssey Monitor, a 6.9-inch S22U phone, and a Nintendo Switch OLED. They managed to clean all of them thoroughly, leaving no noticeable scratches or residue. However, they may be a bit small for optimal use on a monitor, you may want a larger cloth if you are looking for that.

Don’t buy the 3 pack like I did, for the price I should have bought a 10 pack and given away the extras to friends and family. I’m not using K&F Concept Cleaning Cloth for my glasses even though I tried K&F Concept on them, and it worked great. I like leaving a cleaning cloth with my Tablet in its case and another one with my Chrome book. Cleaned the smudges on the glass in a hurry and I like that you can wash and reuse the K&F Concept Microfiber Cleaning Cloth over and over again. I would wash them in a laundry bag to keep them from getting lost in a pant leg and to keep them from catching on edges. The cleaning cloth looks well-made and should last for a long time. The grey looks very stylish as a bonus.

These microfiber cleaning cloths work great. I tried them on my glasses lenses, my phone screen, and my tablet screen. And they did a fantastic job, even without lens cleaner spray. They come individually packaged, which is great, because you can stick the extras in a drawer until you need them and they’ll stay pristine. They are washable once they get gunky, but there are no care instructions. If I had to guess, I’d say wash them with your delicates and don’t use fabric softener. They’re also a handy size to wrap my glasses in when I put my glasses in their case. It’s provides an extra layer of protection for my very expensive lenses—which I really like. Recommended.

Microfiber cleaning cloths are a modern necessity. I’ve seen peoples’ phone, tablet and laptop screens that were so dirty, smeared, gunked up and gross that they gave me the willies. I’m not a neatnik by any means, but clean screens are one of my obsessions. The K&F Concept Microfiber Cleaning Cloths in this three-pack handle the cleaning job as well as any. Measuring roughly six-by-seven inches, they’re a handy size for most uses, although they’re perhaps a little small for huge TV screens. I used one, dry and with minimal pressure, to clean camera screens, and with more pressure to clean my eyeglasses, and it worked fine. For heavy soiling, I moisten a corner of the cleaning cloth with a drop of lens cleaning solution, but I didn’t do that for this tryout because nothing that I used it on was that dirty. The results were as good as I got with any other similar products. I avoid washing cleaning cloths like these because I’m concerned that they may pick up smeary soap residue and/or abrasive contaminants, so I just retire them for non-critical uses like dusting when they get dirty, and use a fresh one for critical optical surfaces. I’ll do the same with these. These microfiber cloths have no distinguishing characteristics that make them better (or worse) than others on the market, so I rate them at a middle-of-the-road three stars. If you need some and the price is right--they’re quite expensive as I write this--then go for ‘em.

Not much you can really say about a cleaning cloth. They pretty much all come standard and feel the same unless you spend a ton more money. I will say though that these do work. As someone who wears glasses for most of the day, I try to keep one of these close to me. They work well with my camera gear as well. These are listed to clean TV screens but honestly if you got a ton of smudges on your screen this would definitely not work. It's just way too small. I would say this would be good for a 27 inch monitor at most.
