How can I purify ash stains out of...
Answers:    If you had precipitation spots, brush them up with coat dryer so it does not dry with flattened fibers.

If own spot that did not come out from the cleaners, take it put money on for a 're-do'. If the stain is milk, beer or raw egg, the stain is unalterable. Perhaps, you got a spot on it after it be cleaned, then use LIGHT clamminess of Woolite & water onto spot, brush, after blow dryer while occasionally brushing to keep fibers up when drying - - Do NOT bring too wet or will hold a water ring.

Perhaps you are looking for a 'protection'; I enjoy not heard of anything you can apply to suede (only smooth leather).
