Do You Need pH Neutral Car Shampoo?

Do You Need pH Neutral Car Shampoo?

Posted in NEWS AND UPDATES by Autobrite on June 17th 2019
If you’re a car enthusiast there are a lot of factors to consider when it comes to cleaning your car and determining which product best suits your needs can be a challenge. You’ve probably seen the phrase ‘pH neutral’ on a wealth of products but understanding what the implications of this can be mind-boggling.So how does the pH of a car shampoo affect your cleaning?

What Does pH Mean?

The measure of pH is a scale of how acidic or alkaline a solution is with 0 being most acidic, 14 being most alkaline and 7 being ‘neutral’. Car paintwork can be tricky to deal with as the paint is typically softer than other types and cars are finished with a number of coatings and sealants to prevent scratches. Using a pH neutral car shampoo simply means that your car is chemically protected and these solutions won’t degrade the paint or any waxes or sealants so the car will stay protected after a wash.

Acid Vs Alkaline

Of course, sometimes you want your car shampoo to clean a little deeper which means removing these layers of wax or finishing products, which calls for acidic or alkaline agents. These cleaning products can usually rid the cars paintwork or any thick layers and give the surface paintwork a more thorough clean but be wary because only a slight tinge of acid or alkali is necessary to do so. Refrain from using products with too high or low pH as these can damage the paint.

What To Use

For everyday washes, a car shampoo with a neutral pH is the quickest option, as once you have washed and dried the vehicle, there is no need for further waxing if your previous layer is unmarred by the wash. However, if you are keen on really detailing a car, using a non-neutral shampoo will allow you a deeper clean but it is vital that you apply wax or finishing agents after the shampoo to ensure the car is protected.
