Pressure Washing Vehicles -
Cleaning & Detailing Chemicals

Issue:

The careless use of high-pressure hot water cleaning equipment and cleaning chemicals may result in damage to certain vehicle components. This bulletin provides guidelines for the use of cleaning equipment and materials.

BACKGROUND:

All electrical equipment on a motor vehicle must be considered as being only "splash proof" with regard to water entry. Electrical equipment must be considered vulnerable if high-pressure jets of water are aimed at components.

Under hood housings for electrical relays and fuses have been proven to be more than adequate in providing waterproof protection under the most extreme conditions of vehicle operation. However, the inappropriate use of high-pressure washing equipment can expose the seals on electrical component housings to water pressure that would not be experienced during driving. This pressure can result in distortion of seals and the entry of water or chemicals into electrical components. Silicones contained in many cleaning products commonly used as additives in vehicle power washing equipment can damage electrical relays.

In addition to electrical components, the following components can also be damaged by power- washing equipment:

^ Plastic external trim components - badges, etc

^ Door and luggage compartment weather strips

^ Sunroof weather strips

^ Head and tail lamp glasses and lenses

^ Windshield wiper blades

^ License plates

^ Hood liners
