FORD 1999 Windstar - Manual (Page 235)

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.
Cleaning the built-in child seat (if equipped)
Clean with mild soap and water. Do not use household cleaning products
because they may weaken the safety belt webbing or damage the vinyl
parts of the seat.
The child seat liner is removable and may be machine-washed and air
dried.
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.
