When to use the best ‘pH neutral’ car shampoo?
‘pH-neutral’ shampoo is something that you can use even daily without stripping car wax coatings or harming car surfaces. They remove maximum contaminants, avoiding protection layers. Acid shampoos or Alkaline shampoos are for deep cleaning of your car, which most of the time includes stripping all wax or sealant coatings.
It means if you apply wax or any other type of protection on your car, for example, car wrapping, you should avoid caustic acid or alkaline shampoos to prolong the effects of protecive coatings.
Frequently Asked Questions about pH Neutral Car Shampoos
Which car wash is pH-neutral?
If you remember chemistry, pH neutral means equal to pH 7. Pure water is pH 7, but I doubt you will meet such perfect water very often outside labs.
In the real world, even water from your hose is not neutral. And if water is not neutral, I hope you understand that soap, which should dissolve some contaminants better than water, cannot be neutral either.
So we can consider ‘pH neutral car wash’ as a marketing name.
‘pH neutral car wash’ – is a wash with pH levels close to pH 7, usually it’s pH 8-9 before dilution. By neutral wash, people usually mean a wash that is safe for car protective coatings, like wax, that can be used with pressure washer and as a hand wash.
How do I know if my car soap is pH-neutral?
The easiest way to know if your car soap is pH-neutral is by checking the SDS of the car soap you are going to use.
Every respectful and trusted brand provides SDS/MSDS of their official websites to every product they sell. There just search for ‘pH’ and you will see pH level of your soap.
If it has a pH 7-9 undiluted (which is usually the case as soaps are sold concentrated), then you can consider your soap as pH-‘neutral’. Above, you can read why ‘neutral’ is just a marketing name.
Are pH-neutral car shampoos safe for all types of paint?
Absolutely! pH-neutral car shampoos are safe for all types of automotive paint, including clear coats and delicate finishes. They work their magic without causing harm or stripping away protective coatings.
Can I use pH-neutral car shampoo on other parts of my car?
Certainly! pH-neutral car shampoos are gentle enough to use on various surfaces, including chrome, glass, and plastic trim. They’re a versatile choice for an all-around clean.
