use the scrim its amazing!
I used to clean windows in Scotland 15 years ago and every window cleaner used scrims just like ABC supples scrims. Im so glad I found them over here in this country. You can clean many windows without swapping out for a dry one, sometimes a whole job. I use them for wiping the end of the glass after iv squeegeed, They are larger but not to much and can hold a lot of water, very little lint, if any and will last at least a couple of years. Definitely a must for pro window cleaners or even home owners. And yes you have to wash it before using.
