SUBJECT: WIPER BLADE SERVICING

The major cause of windshield streaking complaints is contamination of the blade surface and/or windshield with atmospheric contaminants such as oil, dirt and road salt. These contaminants accumulate on the blades and glass during normal driving and can be increased by contact with contaminated car wash brushes or chamois.

The countermeasure to this complaint is a simple cleaning of the blades and glass using isopropyl alcohol. In some cases, it may be necessary to clean the glass using a non-abrasive household cleaner, followed by an alcohol wash. Care must be taken when using such materials to prevent paint damage.

Replacing wiper blades will not resolve the streaking complaint if the glass is oily.

Another factor affecting wiper blade longevity is the surface condition of the windshield. If the windshield is pitted by stone chips, wipers will wear out quickly. This condition is easily observed by using a magnifying glass to inspect the windshield.

These simple procedures can help satisfy your customers, in many cases, right at the Service Writer's area. Service Writers should explain this procedure to the customers also.
