I'm wondering if anyone has had the same experience using the new eco friendly paint thinner, the kind that is milky white. When I used it to clean one of my good finishing brushes I noticed that it lost it's shape and fanned out like old cheap brushes tend to do. It also left the brush feeling like it had a slick oily residue. soaking only made it worse. I had to clean it with the regular thinner about 3 times before the brush regained it's shape and the oily feeling to the bristles went away. Has anyone else had the same problem. As far as I'm concerned this new stuff is junk and a good way to ruin expensive finishing brushes.
