Frequently Asked Questions

What pH level car wash soap should I choose?

pH-neutral soaps are generally safer for all car surfaces, including those with wax or sealant coatings. They are less likely to strip away protective layers. Stronger, alkaline soaps may be needed for heavily soiled vehicles but should be used with caution.

Is it better to use a concentrated or pre-diluted car wash soap?

Concentrated soaps typically offer better value, as a small amount goes a long way. Read the product instructions carefully to ensure you use the correct dilution ratio to avoid streaking or damaging your car's finish and also to not use too much soap which can be wasteful.

What extra features should I look for in a car wash soap?

Look for soaps that offer UV protection and enhanced gloss. These features can help maintain your car's paint, making it more resistant to fading and damage. Some soaps also include hydrophobic properties to repel water and reduce water spotting.
