MAINTENANCE AND LUBRICATION 271

Cab Interior

• For cleaning vinyl upholstery and lining: wipe with a soft cloth, using a good
commercial upholstery cleaner. Do not use acetone, lacquer thinner, etc.
• For cleaning fabric upholstery: use an upholstery shampoo specially
designed for this purpose. Follow the directions on the manufacturer's label.

Waxing

• Always use waxes and polishes that are non-abrasive. Do not use waxes or
polishes that contain silicone.
• When water does not form small drops and roll off clean paint, apply a coat
of good hard wax.
• Even if a liquid wax solution is used on a regular basis, it is advisable to
protect the finish with a hard wax at least twice a year.
• Your truck may have a basecoat plus clearcoat. Use a basecoat/clearcoat
wax on your paint finish.

Polishing

Polish your truck only if the paint has lost its shine and the gloss cannot be
brought back with wax. It is recommended to have a professional polish your
truck to avoid swirl marks or damage to the painted surface. Mequiar's® has a
complete line of waxes, polishes and other cleaning and care products that
are approved for use on MACK cabs, hoods and sleeper surfaces.

Winter Warnings

• If you rinse your vehicle with a hose, avoid direct water into lock cylinders.
You may experience freezing of the lock mechanism.
• Test brakes after each vehicle wash. Moisture and ice on brakes can affect
braking efficiency.
A well kept vehicle can look like new after many years of service. Proper
care and maintenance can help you keep your vehicle's beauty and value.
You can get an assortment of Mack Trucks approved cleaning products from
your local Mack dealer.
