4. Cleaning Heated Glass Windshield/Forward Side Windows

A. Use only approved cleaners and materials when cleaning the windshield/windows. Procedures for cleaning are as follows:

CAUTION: Do not use abrasive materials such as pumice or strong acid based cleaners. These

materials will damage the Surface Seal™

water repellent outer coating of the windshield

and forward side windows.

(2) Using materials, such as a soft cloth or clean sponge, wash windshield/side windows with a 50/50 solution of isopropanol and water. If isopropanol is not available, the following alternate cleaning solutions may be utilized:
