Shampoo spill clean up

Sofa cushions are very absorbent so you will most likely not be able to remove all of the shampoo from inside the sofa. However, assuming your sofa can be cleaned with water (check the tag), you can try to remove the outer stain using a damp clean white cloth alternating with a dry clean white cloth. Blot (do not rub) the stain, alternating between the damp cloth and the dry cloth, working from the outside of the stain to the center, so as not to spread the stain.

If this does not work, you may want to try a professional upholstery cleaning service which may be able to use an extraction method on the shampoo.
