OWNER'S MANUAL - ALUMINUM COSMETIC CORROSION
The information provided is
designed to give you a thorough
understanding of the factors that
can impact the appearance of your
anodized aluminum. By using this
information, we hope to help you
enhance the beauty and value of
our products.
What Causes It?
Corrosion is a natural phenomenon
that affects metals by either a
chemical or electrochemical
reaction. The rate at which alu-
minum corrodes depends greatly
on the environmental conditions
and the amount of preventative
maintenance performed. Our goal
is to slow down or stop this natural
phenomenon we call pitting (or
corrosion).
Anodized Aluminum
The aluminum on your boat has
been anodized. This creates a very
hard protective seal on the surface
of the aluminum to protect it as
much as possible from pitting.
When the anodized coating is bro-
ken and raw aluminum is exposed,
corrosion will take place. Damage
from other abrasive impacts can
break the anodized coating.
Chemical Attack
Corrosive chemicals containing
high concentrations of acids or
alkalis will remove the anodized
coating. Solutions containing
chlorine, salts, or ammonia are all
harmful to the anodized aluminum
on your boat. Many common
household cleaners contain chem-
icals that will remove the anodizing
and cause pitting.
Avoidable Unavoidable
Strong acidic solutions found in cleaners,
paint remover, degreasers, etc.
Airborne pollution. Airborne particles
from local sources: vehicles, incinera-
tors, paper mills, chemical plants, power
plants, etc.
Concentrated alkaline based solutions.
Many concentrated soaps fall into this
category.
Harsh chemicals from work performed
at local shipyards and dry docks.
Chlorine, sulfurs, solvents and ammonia
based products.
Be aware of local sources that can
expose your new boat to corrosive
chemicals.
