A black coffee stain on cream-coloured carpet might seem like a disaster, but don't worry. The stain will probably come right out with a few household products. Just get to the stain quickly, and blot, don't rub, the stain. Rubbing the stain damages the carpet fibres and pushes the stain further into your carpet. Follow a few steps to remove black coffee from cream-coloured carpet.
Blot the coffee stain immediately with a white cloth. Press down firmly on the cloth with your hand until the coffee is completely absorbed. When the cloth becomes saturated, get a new cloth or fold the cloth to expose a dry area.
Test your carpet for colour fastness. Apply a small amount of vinegar, followed by cleaning solution as described below, on an inconspicuous carpet spot (behind furniture, in a closet). If the carpet looks the same, proceed.
Apply a few drops of vinegar to the stain with an eye dropper. Apply enough vinegar to cover the stain area, but don't saturate the carpet.
Blot the stain again with a white cloth as directed in Step 1.
Mix 1/4 tsp dish washing soap with two cups warm water in a bowl or bucket. Apply the solution to the stain using a white cloth. Work from the outside of the stain in toward the centre so you don't spread the stain.
Blot again with a clean cloth. Apply clean warm water to the stain and blot again. Don't saturate the carpet, but rinse thoroughly to remove any soap residue which can attract dirt. Repeat the steps if necessary.
Never use harsh cleaners like ammonia or chlorine bleach on carpets. Plant fibres like jute, hemp, and coir are less stain resistant and more easily damaged than synthetic carpets. Blot stains quickly and place a fan in the room to dry the carpet.
