1. Put them in the freezer for a day, then sand with very fine sandpaper, helps keeps the fuzzie's down.
2. A NEW single edge, or better yet, a double edge razor blade. Double edges blades are thinner and more flexible then single edge, I just put a few layers of tape over one edge, gently and slowly shave off the seam.
3. A hot knife, on a medium temp, I use an old dimmer switch and outlet set up as my temp controller/speed controller, I have a genuine hot knife, but usually just use my 15/30 watt soldering iron. Lightly run the side of the hot knife blade around the seam, not too hot or too much pressure, or you will melt your tire. You should see the seam melting back into the tire before you actually touch the tire.
At home I usually use the hot knife/ soldering iron, but at work, I usually use the freezer/razor blade.
