Should You Use Dish Soap to Wash a Car? What Actually Happens
It’s cheap. It’s in your kitchen. So why not just use dish soap to wash your car?
Here’s the honest truth about dish soap, how it affects your paint, and what you should use instead if you actually care about your vehicle’s finish.
🧪 What Dish Soap Really Does to Your Paint
Dish soap is a degreaser—formulated to break down baked-on oils from your kitchen, not dirt from a clear-coated car.
- ❌ Strips waxes and sealants fast
- ❌ Leaves behind a film that dulls shine
- ❌ Can dry out rubber trim and plastic over time
- ❌ Doesn’t provide lubricity to safely lift dirt
Result: Your paint ends up unprotected and more vulnerable to future damage.
🧼 What You Should Use Instead
Use a purpose-built pH-neutral car soap with high lubricity and safe surfactants. Our go-to: The Super Soaper.
- ✅ Safe for ceramic coatings, waxes, and sealants
- ✅ Foams thick, clings long, and lifts dirt without marring
- ✅ No gloss enhancers or weird residues

🧠 Still Think Dish Soap is “Good Enough”?
In our foam cannon soap comparison test, dish soap failed across the board. Foam collapsed fast, left water spots, and stripped protection in one wash.
Think long-term. Your car deserves better.

Final Thoughts
Dish soap was never made for car paint. It strips protection, dries out materials, and increases the risk of swirls and marring. If you're spending time washing your car, do it right. Use soap that was actually made for the job.
Clean smart. Protect better.
