# CLEANING OF BOSE SPEAKER COVERS PROCEDURE

#### MODELS AFFECTED: 1983 Rivieras

The following addition pertains to the cleaning of the Bose speaker covers on 1983 Buicks.

Always clean a complete speaker cover. Mask surrounding trim.

Mix GM Multipurpose Powdered Cleaner in strict accordance with the directions on the container label.

Apply Spray and Wash, or equivalent, onto a sponge and thoroughly dampen the speaker cover. Do not spray cleaner directly onto speaker cover material. After one minute, apply GM Multipurpose Cleaner.

USE SUDS ONLY ON A CLEAN SPONGE OR SOFT BRISTLE BRUSH. DO NOT SATURATE THE FABRIC OR RUB IT HARSHLY WITH A BRUSH. IMMEDIATELY AFTER CLEANING, COMPLETELY WIPE OFF EXCESS SUDS WITH A CLEAN, DAMP ABSORBENT TOWEL OR CLOTH.

#### NOTICE: Immediately after wiping, force-dry the fabric with a heat gun. Heat gun must be set at the cold setting to prevent fabric damage.

This information will be included in the next printing of the 1983 Riviera Owner's Guide.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
