Last weekend our grandson got gum all over the leather on the seats in our van. Didn't want to use some of the gum removers on the market not being sure how they would do on leather. Did a google search for gum removal tips, several tips out there, just have to pick the one that you want to use. The one I chose is "Scotch Tape", the actual brand of scotch tape is the one that was recommended. IT WORKS!!!! Takes a little time and about a complete roll depending on the amount of gum. Just put it on the gum, rub it in, and pull using a sideways or angle pull. This way there is no smell left and the gum is gone.
