I purchased the SERENITA Dish Cloths for Kitchen.Reusable Disposable Wash Clean Clothes. Melt-Blown Nanofiber. Kitchen Household 60 pcs (Blue) to use for dusting and cleaning. It states that they are reusable and cleanable and there are 60 on the roll so I knew these would last a while. First of all know that these are made in Korea and there are no English instructions at all on the package so be sure to read about them first. They are made like a paper towel roll and after tearing from the perforation they are about the same size as a paper towel. They are a bit rough textured so that makes it great for scrubbing. They are very absorbent. I look forward to using these and seeing about how long each one lasts.I bought it for mask filter but now will use a dishcloth, expensive dishcloth. It is rough enough it should work well scrubbing. I have allergies so maybe it was just me but I felt like something was irritating my nose when I used it in my mask. Removed it and it got better. Not a front line nurse but I have worn enough masks to know this will not work for me.These are awesome! I didn’t expect them to be so textured and easy to use and reuse. They are perfect for cleaning things that are extra dirty that might gunk up your sponge. When I’m done, I just wash it out with some dish soap and water, rinse and hang to dry, and use again. Way more durable than I expected.This is amazing for washing pots, pans that has hard, dried on mess. I love it for many things, but pans are sparkling clean. It will nit scratch anything, and when it gets messy you toss it to the trash. I have one piece for about 10 days of use so it is not that bad too. Amazing discover ?Disposable dish cloths are preferable & more hygienic by far these are Serenita is the absolute BEST...effective at food removal without becoming slimy & odorless - colors fantastic!Not as hardy as I would have liked, they shred apart, but very abrasive so they are good for scrubbing, not for wiping or washingVery rough and scratchy texture. Good for scrubbing, but not at all soft or absorbent like a paper towel. Also expensive. I thought I was getting two rolls, but only got one.Not as useful as I thought. I’ll find ways to use it effectively.
