My son just finished installing new laminate countertops in my kitchen and they look great, BUT, he somehow got a 3" wide and 10" long strip of contact cement on TOP of the new laminate surface. I've tried rubbing alcohol, and other cleaners, but afraid to try laquer thinner because it may take off the color in the new laminate. Any suggestions of how to safely remove the contact cement without damaging the new laminate surface?
