The standard formulations of Dawn dish soap (like Dawn Ultra) are mildly alkaline, with a pH level typically between 8.7 and 9.3. This mild alkalinity provides the necessary cleaning power to cut through stubborn grease and oils without being dangerously corrosive.
Dish soap is usually alkaline, which means it has a higher pH. This chemistry helps break down grease. Car wash soap is typically pH-neutral or specially formulated to safely protect vehicle finishes. Consistent use of higher pH soaps can promote the oxidation of the car's paint and also dry out the trim.
Mild hand soap or normal hand soap works fine, but antibacterial or moisturizing formulas can leave residue or film on the paint. If you're using hand soap or shampoo, dilute it with water to make it gentler on the surface. While it won't tackle tough grease or grime, it's good enough for a light clean.

Dish soap has the ability to lubricate and break down the bonds of fats and grease. When poured into the toilet, dish soap helps lubricate the waste causing the clog, while also breaking down its structure, allowing it to easily flow down the drain.
Mixing vinegar and dish soap creates a highly effective, streak-free cleaning solution. The soap cuts through grease and grime, while the vinegar's acidity dissolves hard water stains and soap scum. However, the acid in vinegar can slightly reduce the soap's foaming ability.

Dilute your car wash soap using a ratio of 1 to 2 ounces of soap per 1 gallon of water (a 1:128 ratio), or simply fill your foam cannon reservoir with 1 part soap and 10 parts water. Always check the manufacturer's label, as specialty formulas may require different concentrations.
Yes, 3000 PSI is generally too much for a car's delicate clear coat and paint. Safe washing typically requires between 1,200 and 1,900 PSI. Using 3000 PSI at close range risks stripping wax, damaging plastic trim, or peeling paint.
The best pressure washer soaps depend on your hardware. If using a foam cannon, high-foaming pH-balanced soaps are best. For an on-board detergent tank, use pressure washer-specific concentrates. Always avoid dish soap, as it strips vehicle wax and dries out rubber trim.
