Proper Car Washing & Car Drying Techniques
How to wash and dry
Don’t… move the sponge in circles. This can create light, but noticeable scratches called swirl marks. Instead, move the sponge lengthwise across the hood and other body panels. And don’t continue using a sponge that’s dropped on the ground without thoroughly rinsing it out. The sponge can pick up dirt particles that can scratch the paint.
Do… rinse all surfaces thoroughly with water before you begin washing to remove loose dirt and debris that could cause scratching. Once you begin, concentrate on one section at a time, washing and rinsing each area completely before moving on to the next one. This ensures that you have plenty of time to rinse before the soap dries. Start at the top, and then work your way around the car. Use a hose without a nozzle and let the water flow over the car from top to bottom. This creates a sheeting action that helps minimize pooling of water.
How Should I Dry the Car When I’m Done?
Don’t… let the car air dry, and don’t expect a drive around the block to do an effective job. Either will leave watermarks caused by minerals in hard water. In addition, don’t use an abrasive towel or other material that can leave hairline scratches in the paint.
Do… use a chamois (natural or synthetic) or soft terry towels. If you choose towels, you may need several. It’s best to blot the water up instead of dragging the towel or chamois over the paint. The drying process can be speeded up by using a soft squeegee to remove most of the water on the body, but be sure the rubber is pliable and that it doesn’t pick up bits of dirt that can cause scratches.
