## Understanding pH and Cleaning Chemistry

The pH scale measures acidity or alkalinity. Solutions with a pH below 7 are acidic and those above 7 are alkaline. In car care, the chemistry of a cleaner affects what contamination it removes and how it interacts with surfaces. Acidic products dissolve mineral deposits and metal oxides, while alkaline products emulsify fats, oils and organic grime.

## What Acidic Cleaners Do

Acidic wheel and metal cleaners use mild acids such as phosphoric or citric acid. They break down heavy brake dust, rust and water spot deposits on wheels, chrome and metal surfaces. Because acids can etch or dull sensitive finishes, use them sparingly and only when necessary. Always rinse thoroughly, avoid polished aluminium and untreated alloys, and never allow acid solutions to dry on the surface. At Parks Car Care we carry speciality acid cleaners for stubborn contamination and our product pages clearly identify when a product contains acids.

## What Alkaline Cleaners Do

Alkaline cleaners contain sodium or potassium hydroxide or other builders that saponify oils and fats. In automotive detailing they excel at removing grease, road film, bug splatter and organic residues. Alkaline wheel cleaners, like those from Koch Chemie or Labocosmetica, are safer on clear coated wheels and are suitable for regular maintenance. Because these products are less aggressive, you can let them dwell longer and agitate with a soft wheel brush to lift grime without damaging coatings. Many all purpose cleaners and pre wash foams fall into this category; look for pH balanced or mild alkaline on the label.

## When to Use Acidic vs Alkaline

Use alkaline cleaners for routine washes and general degreasing such as pre washing paint, cleaning tyres, engine bays and interiors. They loosen dirt and oils without stripping waxes or sealants. When you encounter stubborn contamination like baked on brake dust, heavy rust or mineral scale, use a dedicated acid cleaner for a targeted spot treatment. Always test in an inconspicuous area, wear gloves and protective gear and neutralise with plenty of water afterwards. If in doubt, start with an alkaline product from our Wheel and Tyre Cleaners collection and only reach for an acid when gentler options fail.
