Q: When I use a lambs wool applicator to apply ****** polyurethane the applicator sheds lint and contaminates the finish. I am using a new applicator right out of the box. Should it be washed first to remove the lint or is there another trick?
A: I usually vacuum/shake/ brush them first, and then throw them in the washing machine (without soap), then lay them out to dry. If it still drops a few during the first coat, it doesn’t really matter, since you have to buff the floor between coats anyway.
