1. Buy bargain tires marked "blems." They are perfectly serviceable except for minor cosmetic blemishes on sidewalls.
2. Lengthen the life of old windshield-wiper blades by rubbing the edges with a knife or the striking part of a matchbook cover. This exposes the softer material underneath and improves the wiping ability of the blades.
3. Preserve the car's finish by washing it with cold or lukewarm (never hot) water.
4. Run the air conditioner at least ten minutes every week, regardless of season. This procedure will maintain coolant pressure and avoid costly air-conditioner breakdowns.
5. Clean corrosion off the battery terminals, using a wire brush or steel wool to scrape battery posts and cable clamps. Clean the top surface with a mild solution of baking soda and water, without letting it seep under cell caps.
