How do you remove tea stain from light blue jeans?

Since your tea stain is on denim, you can treat it by applying Liquid Clorox^® 2 Stain Fighter & Color Booster into stain and rub it in. Wait for 5-10 minutes, then wash immediately in the hottest water recommended using detergent and Clorox^® 2 Stain Fighter & Color Booster. Allow to air dry and check to make sure the stain is completely removed. It's important to keep a stained item out of a hot dryer to avoid heat setting any residual stain. That way if any stain remains, you can repeat the treatment as needed.
