How to clean coffee stains
Blot the coffee stain immediately.
If the stain is still damp, blot with paper towels or tissue. Use a blotting, up-and-down lifting motion to soak up the coffee.

Options are: [i] Do not rub the paper towel from side to side because this may spread the stain. Use white paper towels because towels with patterns could leak dye onto the fabric and create even worse stains. [ii] Turn the paper towel upside down (make sure the bottom edge is flat) and gently blot and lift the coffee stain. The stain should be swept away from the surface and over to reveal a clean area. [iii] Keep blotting until the stain is gone. After any liquid has been absorbed, unfold and repeat steps 8-10 again, focusing on the area to have stained and applied the stain. [iv] Add more paper towels, or a towel wrapped around the coffee stain. Alternately, you could try blotting with a sponge to get the stain back into position.
