First, absorb as much of the spilled coffee stain as possible with a dry cloth. If the coffee is milky, apply cold water to it. Then, if it is the cloth where the coffee stain is spilled, turn it upside down. Reduce the coffee stain with the help of cold water. Add Peros Bright Colors Detergent, which does not contain bleach, to the water in a bowl to obtain a mixture and apply to the area with the coffee stain. Leave the final detergent mixture on the coffee stain for a while. After the stain is less visible, wash it in your washing machine with Peros detergent.
