I use these in conjunction with the Novus plastic polishing system. They are fairly expensive but worth the outlay as they leave a scratch free finish after final polishing.

The six pack is the same ones that come with the polishing Kit.. Soft and semi reusable. Note the 10 pack are not the same even though the pictures are the same... There are very different.

Wonderful

The material seemed over priced for what it is: Essentially a (paper?) based microfiber cloth that does what it says it will do, yet you can only get so many times of use out of each sheet. You have to be careful when you're not using it so that it does not pick up any dirt or dust; otherwise it will scratch the surface of your acrylic. I have not tried to wash these, but I doubt they would hold up well, and I believe these to be disposable rather than reusable. Nice if they were cheaper.

Did an excellent job of cleaning my motorcycle wind screenLooks like new now.
