FORD 1999 Ranger - Manual (Page 199)

Cleaning the interior fabric
Remove dust and loose dirt with a whisk broom or a vacuum cleaner.
Remove fresh spots immediately. Do not use household or glass cleaners.
These agents can stain and discolor the fabric. Use a mild soap and
water solution if necessary.
Cleaning and maintaining the safety belts
Clean the safety belts with a mild soap solution recommended for
cleaning upholstery or carpets. Do not bleach or dye the belts, because
these actions may weaken the belt webbing.
Check the safety belt system periodically to make sure there are no
nicks, wear or cuts. If your vehicle has been involved in an accident,
refer to the Safety belt maintenance section in the Seating and safety
restraints chapter.
Underbody
Flush the complete underside of vehicle frequently. Keep body drain
holes unplugged. Inspect for road damage.
Inside windows
Use glass cleaner for the inside windows if they become fogged.
Cleaning mirrors
Do not clean your mirrors with a dry cloth or abrasive materials. Use a
soft cloth and mild detergent and water. Be careful when removing ice
from outside mirrors because you may damage the reflective surface.
