How to Remove a Set-In Ketchup Stain from a Polyester Couch

Set-in ketchup on a polyester couch is a common and frustrating problem. The tomato base leaves a bright orange-red mark, and the oil in the ketchup can make it cling to the fibers. But you don't need harsh chemicals to fix it. With dish soap, white vinegar, and a little patience, you can lift the stain without damaging the fabric.

What to Do First

Act quickly, but don't rub. Rubbing pushes the stain deeper into the fibers. Instead, use a clean white cloth or paper towel to blot the area gently. This removes any excess ketchup that hasn't dried completely.
