Baking Soda Solution
Truck battery exterior surfaces, terminals, and cable clamps should be cleaned with a weak solution of baking
soda (item 5, Appendix B) and water. A bristle brush soaked in the solution may be used to remove caked
dirt or corrosion products
Solvent Spray Gun
Spray gun must be used in spray booth with filter and face shield for personnel since dry cleaning solvent
(item 10, Appendix B) is toxic to skin, eyes and lungs. Avoid prolonged or repeated contact
Radiator cores should be cleaned with steam or hot water. If sediment within the core cannot be completely
removed in this way, core will have to be boiled in a chemical bath. This bath is a strong solution of caustic
soda and is available in a radiator repair shop
Painted surfaces (e g. truck body) shall be cleaned with a detergent solution and a pressure washer.
Always rinse surface with clean water.
Although the truck body paint is very durable, certain solvents may damage the paint. Keep solvents away
from painted surfaces. A pressure washer should be used to remove excessive road dirt, oil, and grease
from exterior parts prior to dismantling.
Oil and fuel tanks should be flushed with steam for at least 24 hours before welding or repairing such tanks.
Ball and Roller Bearings
When cleaning ball or roller bearings, place them in a basket. Suspend the basket in a dry cleaning solvent,
(item 10, Appendix B) preferably, overnight. If needed, use a brush to remove caked grease or chips. Avoid
rotating the bearings until all solid particles are removed. When bearings are clean, spin them in a light
lubricating oil (item 17, Appendix B) to remove solvent.
Do not clean preformed packings or other rubber parts in solvent. These parts should be wiped with a clean,
dry, lint-free cloth
Electrical components (e.g coils, switches) which use insulating materiels shall not be soaked or sprayed with
cleaning solutions. Remove dirt with a clean, dry, lint-free cloth If necessary, moisten cloth with dry cleaning
solvent (item 10, Appendix B).
