Worked well on a wool rug!
I spilled coffee with milk on our wool area rug.  I immediately used warm water and clean white towels to get as much of the stain up as soon as possible.  After initial clean up I ordered one can of this product because there was still a stain and outline of the spill.  It took about three applications (just as the directions suggested-repeat) but the stain was removed without any damage by this product to the rug.  Recommended.
