Q: After 1st wash, even before 1st use. It became unusable: full of tiny cotton balls on the surface; shrank 20% at least; tended break. Note that I did follow the wash direction.Now I have to cut them into pieces and see if they are any good for wiping dirt off my car. It not even worth the return postage.
A:
Negative
