Washing your car is not just needed to make your car look better as you drive down the road. Regular washing can help maintain the vehicle and keep its value, thus saving you money now and earning you more money later should you try to resell it.

That said, washing your car incorrectly can do more harm than good. We asked our experts how to properly wash a car. Here’s how to do it.

Clean Before You Wash

First, make sure to move your vehicle to a proper location before washing. Never wash a hot car. The vehicle should be cool to the touch and out of direct sun light.

Once you’re set to get the car clean, start by getting rid of any debris on your car (underneath the wiper blades is a good place to start). Clean any bug, bird dropping and tree sap stains. To do so, use denatured alcohol or a bug and tar removal.

You can then get the vehicle good and wet to wash off any accumulated dirt. Rinse off the entire car prior to hand-washing. Since you have the hose out, rinse the undercarriage (under the vehicle) as well as inside the wheel openings to wash off any accumulated dirt.

PRO TIP: Get your bug and tar removal at NAPA Auto Parts, where AAA members receive 20% off.

How to Properly Wash a Car

Do not use household cleaners such as hand or dish soap. These products can strip off the car’s protective wax. Instead, use a dedicated car wash soap. These products are milder and specifically designed for use on automotive paint.

When washing your car, use the two-bucket method. One bucket will have the clean, soapy water, the other is where you’ll drop the dirty water. Using only a single bucket requires you to repeatedly dip the sponge into dirty water, thus putting dirt right back on the car you’re trying to clean. Not only is it counterproductive, the dirt could damage the paint.

When you’re ready to begin washing, do so from top to bottom, focusing on one section at a time. Use lots of water and rinse off each section of the car as you move along. This will prevent the car from air drying. (More on that below).

PRO TIP: Wash the wheels first with a special wheel-washing brush with soft bristles for the tires. This brush will enable you to get in all the nooks and crannies.

Drying the Car

Do not forget to hand-dry your car. Allowing it to air dry will leave behind streaks and water marks. To properly dry the car, use a chamois or fluffy microfiber cloth.

This is a good time to use a quick detailer spray wax or paint sealant. It doesn’t replace hand-waxing to help protect the paint but it is a quick and easy step.

Cleaning the Windows

Once the car is dry, it is time to clean the windows. To do so, use a high-quality window cleaner. Spray the cleaner on the windows and wipe down with paper towels. Remember to open the windows to get the top area that slides up into the door. Once the windows are clean go over them with a microfiber cloth to remove any extra cleaner spray.

PRO TIP: Use a few-weeks-old black and white newspaper to clean your windows rather than paper towels for the least amount of streaks.

    I use a product called Absorber. Neoprene sheet that picks up water and leaves surface dry by second time around. Put it away wet for next use. Had 13 years. When sorayingbtires, spray and move car a bout three feet to get the bottom qtr of tire to complete the application.

    No reference to rinsing under the car or wheel wells, both areas a good idea especially during the winter.

    This is very interesting, and I’m sure useful, for those who have access to an outdoor hose and sufficient car space to use it. What about those of us who don’t? I take my car to a “self-wash” and use the power water/soap/rinse features. Is this OK? What about full-service car washes? What is best in this arena?

      Hi Margaret, here is an answer from our Car Doctor John Paul. You can reach him at jpaul@aaanortheast.com if you have any other questions.

      A. Using a hand-held car wash is fine, but there are a couple of things to keep in mind. The first is that the water is under high pressure and you need to be a bit careful about how and where you pressure wash the car. It is even possible to lift the paint if you apply high pressure water to a paint chip. The second issue and this applies to drive through washes is that the water is recycled and at certain times of the year, the water could be contaminated with salt or other corrosive materials.
      B. Full service or tunnel wash bays can be abrasive to the paint, the brushes are similar to indoor/outdoor carpet or nylon brushes — both can scratch and dull the paint.
      C. If it is a car wash tunnel, hand held or garden hose all are better than allowing the car to be covered with salt and sand. So whenever possible try to wash sand, salt and other corrosive road clearing products off the car.

      With removing tape adhesive, I have had good luck with denatured alcohol or a Goo-Gone. This should soften the dried adhesive so you can carefully clean it off. Never use a hard scrapper, if necessary use a plastic scrapper. Once the adhesive is off the paint, clean and then wax the car. The alcohol or Goo-Gone will remove any wax.

    To make white raised letter tires. Put Soft Scrub “With Bleach” on the White with a sponge. Let a sit for about 15 minutes. Take a hand brush and brush letters then hose off. White is back!
