Debbie_BayVillage:Try to pick off as much as you can. You can try rubbing the spots with an ice cube, which is supposed to make it easier to remove. Scrape with a table knife. Then spray with something like Spray & Wash or some other laundry pre-treatment spray.
I just did this 3 weeks ago. Do as Debbie says with the scraping & all. I sprayed it then with Oxy-Clean stain remover.I had to scrape again after I sprayed.You can tell if you get all the gum by turning inside out & seeing if the spray penetrated...if not spray the underside as I had to do & scrape again on right side. I laundered as usual & it was all gone.......
Good Luck!
