Dried coffee on a wool sweater is a frustrating surprise. The brown mark has had time to set, and wool is delicate, so you can't just scrub it. But you can still lift the stain with gentle household staples like dish soap and white vinegar.

Why Dried Coffee Stains Are Tricky on Wool

Wool is a natural protein fiber. It's strong but sensitive to heat, harsh chemicals, and vigorous scrubbing. Dried coffee has had time to bond with the fibers, making it harder to remove than a fresh spill. The key is to re-wet the stain, break it down with a gentle cleaner, and blot—never rub—to avoid damaging the wool.
