How to Remove Set-In Grass Stains from Khaki Chinos

Grass stains on khaki chinos are a classic warm-weather problem. The green pigment from grass can bond tightly to cotton and cotton-blend fabrics, and once it sets in, it becomes tougher to shift. If you're dealing with a dried or set-in grass stain, don't panic. With the right approach and a few household staples, you can often lift the mark without damaging the fabric.

This guide focuses specifically on set-in grass stains on khaki chinos. Khaki is a light, neutral color, which means stains are more visible, but it also means you need to be careful with harsh chemicals that could bleach or discolor the fabric. We'll walk you through a safe, step-by-step method using dish soap, white vinegar, and baking soda—all gentle enough for most chinos.

What to Do First

Before you start any treatment, check the care label on your chinos. Most khaki chinos are made from cotton or a cotton-polyester blend, and they can usually be machine washed. However, always follow the manufacturer's instructions. If the label says dry clean only, consider taking the garment to a professional instead of trying home remedies.

Next, gently scrape off any dried grass residue with a dull knife or the edge of a spoon. Be careful not to rub the stain further into the fabric. Then, rinse the stained area with cold water from the back of the fabric to push the stain out rather than deeper in. Cold water is key—hot water can set the stain permanently.
