I dropped a glass of regualar hot milk on the sofa which has been applied with Scotchgard. There in no stain or smell. But it is starchy and stiff. How do I take the stiffiness out?
You didn't say what the covering fabric of the sofa is, but you could try a soft bristle hairbrush, like a baby hairbrush, or a soft-med bristle toothbrush. Use these dry to gently brush the area to remove the stiffness. Rate of success probably depends upon the type of upholstery. Worth a try.
