Cleaning Tips
Dos Don’ts
Use a cloth to wipe off solvent or use compressed
air to blow off the solvent.
Except when removing carbon deposits and gum
(oil varnish), do not use alkaline (caustic) cleaning
solutions for external engine cleaning. Alkaline
solutions remove the alodine finish of aluminum
parts.
Remove dirt (especially caked dirt) and debris from
bolts, nuts, and engine parts.
Do not use any of the following to clean the engine
or its parts:
•
Gasoline
•
Kerosene
•
Abrasive cleaning paste
•
Cleaning
powder
Dispose of cleaning solvents in accordance with
Environmental Protection Agency (EPA)
regulations.
Do not scrape parts or use wire brushes,
sandpaper, abrasive cloth or abrasive wheels to
clean or polish parts to prevent concentrated stress
to scratched areas and fatigue failure.
Dry blast only with plastic media or natural
materials such as wheat grains
Do not use sand, metal grit, or glass beads for any
type of cleaning or dry blasting.
After a part is cleaned, machined or repaired, or if
the alodine finish is worn, apply alodine to
aluminum surfaces, according to “Alodine” in this
chapter
Do not tumble blast wrought or die cast smooth
surface parts such as rocker covers or intake
tubes.
