Matte Paint Care Guide
■If dirt cannot be washed off with water alone
●Water stains
If liquid, such as rain water or tap water, evaporates on a painted surface, dirt or miner-
als in the liquid may be left behind. If not cleaned off, the contaminants may settle into
the textured surface of the matte clear coat, making it difficult to clean off with water
alone.
In this case, to remove the contaminants, use
dilute citric acid.
Dissolve citric acid powder in distilled water
at the following ratio:
Citric acid powder: 0.01 to 0.02 lb. (5 to 10
g) (1 to 2 teaspoons)
Distilled water: 0.2 qt. (0.2 L, 0.2 Imp. qt.)
Thoroughly soak a soft chamois cloth in the
citric acid and place the chamois cloth over
the dirty area. Wait for the contaminants to be
dissolved by the acid. Then, gently wipe the
area several times with the chamois cloth, tak-
ing care to not rub the vehicle body. After
that, apply plenty of water to the area to wash
off the contaminants and acid.

●Dead insects, bird droppings, and oil stains
If these materials are not cleaned off, contaminants, such as proteins and oil, may settle
into the textured surface of the matte clear coat, making it difficult to clean off with

Thoroughly soak a soft chamois cloth in the
neutral detergent solution, covering it in the
lather, and place the chamois cloth over the
dirty area. Wait for the contaminants to be
dissolved by the solution. Then, gently wipe
