Part 1: Material and risk

Spilled coffee on your polyester couch and didn't catch it in time? A dried coffee stain can look permanent, but with the right approach, you can often lift it. Polyester is a synthetic fabric that's fairly durable, but it can be sensitive to heat and harsh chemicals. This guide walks you through a safe, step-by-step method using common household items.

What to Do First

Before you start, check the care tag on your couch. If it says "W" (water-based cleaner) or "S/W" (solvent or water), you can proceed with the methods below. If it says "S" (solvent only), skip the water-based steps and use a dry-cleaning solvent instead. Also, test any cleaning solution on a hidden area first to make sure it doesn't cause discoloration.
