Agree with Z. I've used he sonax stuff with great results. Let it sit for a minute then take a damp cloth and start dabbing it to get anything out. Then switch to a new side of the cloth. After you do that start rubbing in circles. Let dry and then use a soft bristled brush to slightly agitate the material back to its natural shape. If it's not really bad then you could also use mild soap and water on said cloth instead of sonax.
