based stains not removable with water?
For oil stains [e.g., street grease, oil, etc.], slip off the cover. Place the outside [stain] face up on the kitchen counter with several paper towels under the stain to protect the counter. Soak and wipe up as much of the oil or grease as possible with paper towels on the outide. Use as many paper towels as necessary. Try not to spread the stain. Next, take two clean rags: a big dry one and a smaller 6″ x 6″ cloth soaked in ethyl [rubbing] alcohol. Use the alcohol-soaked cloth to pat the stained area from the outside. Then pat off the loosened dirt & oil onto the dry rag. If the stain is resistant, repeat the process again. After the stain is gone, let your cover air-dry fully before putting it back on. If the stain was extensive, cold-water-wash your cover in the washing machine and then line dry it. [Caveat: Never pour any cleaning product directly onto a microsuede fabric.
