My kids were home over Thanksgiving weekend, and I had other friends and family visiting. After they all left, I started cleaning up. I discovered sticky marshmallows smeared and stuck to a sofa cushion and on a throw pillow. Yuck.
I tried scraping it off, but it just pulled at the fabric. Dabbing with water did nothing. I was afraid of using a strong solvent that might stain or hurt the fabric. I tried ethyl (rubbing) alcohol. It worked like a charm. I soaked a little bit of a white towel with alcohol, then blotted the marshmallow laden fabric with it. It dissolved the marshmallow enough that I could easily dab and gently rub it off. It dried quickly and no left over film, stickiness or stain on the fabric.
