Acetone does dissolve paint . . . but the first time I used that method I was deflocking a ratty SS to use as a custom base and I actually stripped off all the flocking without damaging the blush or symbols. I had to scrub with additional acetone to remove the symbols.
Nevertheless I was more cautious with later deflocks (because I wanted to keep them as 'themselves') and on those I did the acetone around the symbol, then scraped off the fur over the symbol using just hot water and scrubbing.
