How to Remove a Set-In Grease Stain from a Cotton Denim Jacket

A set-in grease stain on a cotton denim jacket can leave a dark, oily mark, but you can lift it with dish soap and baking soda. Here's a practical guide for set-in stains, with denim-specific care tips.

Part 1: Material and risk

Grease stains on a cotton denim jacket are a common frustration. Whether it's a splash of cooking oil or a smear from a bike chain, the oily mark can set into the fabric if not treated quickly. But even if the stain has been there for a while, you can still lift it with a few household staples. This guide focuses on set-in grease stains on cotton denim, offering a step-by-step method that is safe for the fabric and effective at breaking down the oil.

What to Do First

Before you start, check the care label on your jacket. Most denim is machine washable, but some may have specific instructions. If the label says dry clean only, consider taking it to a professional. For washable denim, you can proceed with the following method.
