Old coffee stains leave can leave unsightly, pale brown stains on your clothes, carpet and anywhere else you've had the misfortune of spilling coffee. The focus here is on how to remove old coffee stains that have had plenty of time to set and dry into the material.
Prep the Stain
Blot the stain with a wet, white towel (use white only to prevent color bleeding into the fabric) or paper towels dipped in water. Spray foam shaving cream on the stain and gently work it into the fabric or carpet fibers. Don't rub too hard for risk of damaging the material. Blot the stain again with a clean, wet, white towel or paper towels.
More Aggressive Action
If you still have a stain, make a paste of baking soda and a couple of teaspoons of water. Rub the paste into the stain to draw out the coffee. Let the paste set on the old coffee stain for an hour, then blot once more with a wet, white towel.
Vinegar & Water
An alternative solution is to mix a 1/2 cup of vinegar with 1 cup of warm tap water in a plastic spray bottle. Spritz this mixture onto the stain and rub gently with a clean white towel. Rub in a circular motion from the outside of the stain to the center to avoid spreading the stain around.
Repeat these strategies until the stain is gone, then let the spot air dry. If cleaning stain from a carpet, allow to air dry, then vacuum to restore the carpet fibers.
