Try using a piece of paper towel instead of cotton. It won't leave as much alcohol on the blade. Also, when you cut the root stock, Cut a second thin slice and leave it on the end of the rootstock. Then you can wait for the alcohol to dry, cut your scion and then just push the thin slice off to place the scion on to the rootstock.
Don't worry about rushing too much. Just take your time.
