I called Gold Tip a few years ago to be sure that using acetone was OK and the engineer I talked to to said it was absolutely OK to use it. He told me that I could soak the shafts in it if I wanted to. That is how I use it now. I just cut the vanes off down to the base , then I have a tall narrow glass vase that I put enough acetone in to soak the vane end of the shaft in. I will leave it sit for about 5 minutes or so and the take them out and the vane base and the glue will scrape right off with a very dull old filet knife. I then wipe them off and clean them with warm soapy water and the are ready to refletch. Also be sure and clean the inside of the end of the shaft with the soapy water so the nock doesn't melt from the acetone. I have been doing this for the past few years and have had no problems at all. Be sre to keep the acetone off of your skin and use it outside because it is some nasty stuff. I use rubber gloves when doing it.
