can you use dial soap to wash your car

[EvelynMarie]

No, you should not use Dial soap or any similar hand or body soap to wash your car. While it will remove surface dirt, these soaps are formulated for skin and can seriously damage your car's exterior over time. The primary risks are stripping the protective wax and sealant and degrading the clear coat, which is the transparent layer that protects your car's paint.

The problem lies in the chemical composition. Hand soaps are often de-greasing agents designed to cut oils on skin. Your car's wax layer is a protective oil-based coating. Using Dial soap effectively washes this protection away, leaving your paint vulnerable to UV rays, acid rain, and contaminants. Furthermore, these soaps can be too alkaline, which is harsh on automotive paint and can cause it to become dull and oxidized.

For a safe and effective wash, you must use a pH-neutral car wash soap. These are specifically engineered to lift grime without compromising your wax or paint. They also contain lubricants to help the wash mitt glide over the surface, preventing swirl marks and scratches.

Product Type	Typical pH Level	Effect on Car Wax	Effect on Clear Coat	Recommended Use
Dial Hand Soap	9 - 10 (Alkaline)	Strips it completely	Dulls and degrades over time	Washing hands
Dish Soap (e.g., Dawn)	7 - 8.5	Strips it completely	Can cause premature wear	Degreasing engines only
pH-Neutral Car Shampoo	6.5 - 7.5 (Neutral)	Preserves it	Safe for regular use	Washing car body
Waterless Wash Spray	~7.0 (Neutral)	Preserves and can enhance	Safe for light cleaning	Quick detail between washes

If you've already used hand soap, the first step is to thoroughly rinse the vehicle to remove all residue. You should then plan to reapply a fresh coat of wax or sealant as soon as possible to restore protection. For routine maintenance, investing in a dedicated car wash solution is non-negotiable for preserving your vehicle's value and appearance.

Trust me, it's a bad idea. I tried it once in a pinch, and it left a hazy film on my black paint that was a nightmare to get off. It completely wiped out the wax, and my car looked dull after the next rain. It's just too harsh. Spend the ten bucks on actual car soap—it’s cheaper than a new paint job. Your car’s finish will thank you.

Think of it this way: you wouldn't use laundry detergent to wash your hair. Dial soap is made for skin, not automotive clear coats. Its job is to strip oils, which is exactly what your car's protective wax is. Using it removes that shield, leaving the paint underneath exposed to sun and pollutants. Always choose a product designed for the task, like a pH-balanced car shampoo, to keep the finish safe and glossy.

From a chemical standpoint, the risk is the pH level. Automotive paint and clear coat thrive with a pH-neutral cleaner, around 7.0. Most hand soaps, including Dial, are alkaline, often with a pH of 9 or higher. This alkalinity can slowly degrade the clear coat, leading to oxidation and that chalky, faded look you see on older, neglected cars. A dedicated car wash soap maintains the correct chemical balance for longevity.

I view everything through the lens of long-term value. Using the wrong soap might save you a few dollars today, but it accelerates the depreciation of your car's exterior. A damaged clear coat is expensive to correct. Protecting your investment means using the right tools for the job. Proper car soap is a minor expense that preserves your paint, maintains resale value, and keeps the car looking new for years. It’s a simple, smart preventative measure.
