If I’m in a people sensitive home I’ll attempt to remove gum using Orange Deodorizer, after using gum freeze. I also use my sizzers from my pocket knife in an attempt to scrape it from the fibers instead of cutting with the razor blade. Cutting of course being the last resort.
Sometimes you get lucky and it scrapes off without having to use any products but as mentioned above, dry solvent is the way to go. Use your “tool” or razor blade when customer is not around.
