Adding Windshield Washer Fluid - Ford Vehicle Owner's Manual

Adding windshield washer fluid

Use specially formulated windshield washer
fluid rather than plain water, because specially
formulated washer fluids contain additives that
dissolve road grime. For safety reasons, washer
fluids containing an appropriate antifreeze such
as methanol should be used in freezing weather
(temperatures below 32˚F [0˚C]). State or local
regulations on Volatile Organic Compounds
(VOC's) may restrict use of the most common
antifreeze, methanol. Washer fluids containing
non-methanol antifreeze agents should be used
only if they provide cold weather protection
without damaging the vehicle's paint finish,
wiper blades, and windshield washer system.
If you choose to use a windshield washing
solution that must be mixed, follow the
manufacturer's mixing instructions. Improperly
mixed solutions may freeze unexpectedly.
NOTE: The addition of shields to the front of
the vehicle, as used to deflect bugs,
may also adversely affect the washer
system from delivering fluid to the
windshield. Devices such as bug
shields are not recommended to be
added to your new Ford product.
