Using Solvent-Type Cleaner on

mild soap.
If you need to use a solvent:
Gently scrape excess soil from the
trim material with a clean, dull knife

When you clean a stain from fabric,
immediately dry the area with an air
hose, hair dryer, or heat lamp to help prevent
a cleaning ring. (See the
previous NOTICE.)

and clean as you would any other
carpet.
Care of Safety Belts
Keep belts clean and dry.
