  • Safety – A quality soap should wash clean without leaving behind streaks or soap scum that can damage paint or glass over time.
  • Ease of Use – A good soap rinses cleanly without difficulty so washing your car is simple and quick.
  • Value – With bulk sizes available for many soaps, you can save money in the longer term on cost-per-wash.

How to Wash Your Car Properly

Best Car Wash Soaps

Choosing a quality car wash soap is the first step toward keeping your car looking its best. But technique is important too or you could accidentally add imperfections to the paint while cleaning it. Here are some tips for washing safely:

  • Rinse First: Start by spraying off as much loose dirt as possible with a hose. This prevents the grit from scratching the finish as you wash. Use a nozzle with a wide fan spray. Avoid pressure washers which can damage paint.
  • Work Top to Bottom: Apply soapy water starting with the roof and upper panels. Then work down cleaning lower body panels last. This avoids dirt dripping onto already cleaned sections.
  • Use Microfiber Mitts: Choose microfiber washing mitts which are super soft and designed not to scratch delicate surfaces. Avoid using sponges which can be abrasive.
  • Don’t Let Soap Dry: As you work, keep wetting panels you already started to prevent soap from drying which makes scratches more likely. Frequently rinse mitts too.
  • Scrub Lightly: Don’t bear down too hard when cleaning. Modern clear coats are durable but still micro-sensitive. Let the soap do the work instead of muscle power!
  • Dry Thoroughly: Chamois cloths, towels made from high-tech synthetic materials work best. Make sure to dry all cracks and crevasses completely so moisture doesn’t linger.

Putting some extra care into your wash process helps keep swirls and cobwebbing to a minimum so you can enjoy that freshly detailed look longer!

Frequently Asked Questions

What is the best way to use car wash soap?

  • By Hand – Mix 3-6 ounces of soap per gallon of water. Wash from top down using a sponge or wash mitt. Rinse thoroughly.
  • Foam Cannon – Dilute 1-2 ounces per 32 ounce bottle. Adjust the pressure washer dial for rich foam then coat the car. Do not let the solution dry before rinsing.

How often should I wash my car?

To help maintain the paint, wash every 2 weeks or whenever it looks dirty. Wash more frequently if driving on salted winter roads.

Do car wash soaps really make a difference?

Yes, the right soap lubricates away stuck-on contaminants far easier and safer than dish soap or all-purpose cleaners. Car shampoos also contain gloss enhancers and other helpful ingredients.

Can I wash my car with only water?

It’s best not to. Water alone struggles to dissolve and lift away grime. Plus it doesn’t provide any lubrication or added shine that a good car wash soap offers.

What scent car wash soap do you recommend?

This comes down purely to personal preference. Many enjoy fruity or sweet scents like cherry or lemon. Unscented formulas work well for those sensitive to fragrances too.

The Bottom Line

Regular car washing using a specially designed automotive shampoo provides lubrication to lift away grime safely and quickly while also boosting shine. pH balanced formulas with gloss enhancers that protect the finish are recommended.

Top rated all-round soaps come from quality brands like Meguiar’s and Chemical Guys. But you can also choose specialty formulas depending on your priorities – whether that’s boosting protection, achieving a brilliant wet-look shine, or effective cleaning of delicate surfaces.

Whichever car wash soap you choose, follow the usage instructions carefully and wash safely in the shade when surfaces are cool to the touch. This keeps your vehicle’s paint finish looking its best for many years.
