I believe that dry cleaning may take care of the stains in that grill cloth, which basically means they use perchloroethelene which is also found in automotive brake cleaner. Another method would be to use a carpet cleaner on it, either the spray on stuff or a steam cleaner that will suck the water out of it. If you do go for any cleaning involving water leave it on the board, maybe even staple it down, or the fabric will shrink.
