Wash off with water immediately.
If the contaminants cannot be removed with
water alone, use a neutral detergent solution. If
the contaminants are allowed to remain on the
vehicle, they may settle into the matte clear coat,
making it more flat. As a result, it will become
more glossy, possibly permanently losing its
matte properties.

in distilled water) to remove the water stains.
Remove immediately.
Even if removed, depending on the contaminant,
