Best Car Wash Soap 2020 – Professional Grade Car Washing Soaps

Soap making was elevated to an art in 7th Century Europe but it wasn’t until the 19th Century that petroleum-based detergents that resisted hard water were introduced to the marketplace. Enter the automobile, a status symbol that required regular cleaning and lead to the establishment of the first manual car wash in 1914. Automation was introduced in 1946, but not every car owner trusted their rides to those rudimentary machines.

Over time, specialized products were made that differentiated the needs of auto bodies from other types of surfaces, culminating in the formulation of special products sold just for car detailing. Historians at AutoLaundryNews.com note that “these detergents were anionic surfactants that basically made water wetter.”

Today, the sheer variety of chemical agents sold to help car owners keep their rides pristine has heightened competition between manufacturers who pride themselves on producing car wash soap formulas that focus on surfactants and alkaline builders like phosphates, metasilicates, sodium and potassium hydroxides. Added chelating agents have not only stabilized formulas but improved hard water stability, so no matter which car wash soap you choose, your car can always look like it lives in a garage (even if it doesn’t!).


How to properly wash your auto using car wash soap

1. Shop for a product that gets good reviews from users and invest in the right towels and cleaning mitts.
2. Rinse the car first to remove large pieces of dirt.
3. Follow directions on the car wash soap label to either dilute or apply the product.
4. If, after towel drying, stubborn soil remains, try using a clay bar to remove it.
5. Don’t use auto soap on windows, wheel rims and trim; use products formulated just for those surfaces.


More advice for car washers

– Use chrome wheel cleaner on aluminum rims and the acidic content of the product could ruin them.
– Avoid using dish soap; you could damage paint and/or strip off wax.
– Launder towels and mitts after each wash was to avoid dirt transfer.
– Keep a spray bottle of car wash soap on hand for touch-ups.
– Windex or other ammonia-based solutions can damage tinted windows.
– Use acid-free, pH-balanced products on metal surfaces like wheels.
– Use only the best car dusters – Don’t scrimp on price.


What to look for when buying car wash soap

Leave it to car buff and former late-night talk host Jay Leno to advise us on the subject of picking a car wash soap:

1. Check out the product’s “lubricity.” “The slipperier the better!” says Jay.
2. Make friends with suds and foam; they’re the dynamos responsible for trapping and lifting dirt.
3. The car soap you adopt should be pH balanced so acidic residue doesn’t ruin the car’s finish.
4. Jay urges shoppers to choose biodegradable formulations to be kind to the environment.
5. If all you want to do is keep your car exterior clean, add a general-use shampoo to your shopping list.
6. Only use a stripping solution when you intend to wax the car immediately afterward.
