Engine Detailing Myths Busted
From “you’ll fry your car” to “never use water,” here are the most common engine detailing myths — and the truth behind them.
Engine detailing has always been surrounded by myths, half-truths, and horror stories. Ask ten people whether it’s safe to wash an engine, and you’ll get ten different answers — from “absolutely not” to “blast away with a pressure washer.” The reality is somewhere in the middle. When done correctly, engine bay cleaning is safe, effective, and one of the best ways to keep your car looking and performing its best.
In this post, we’ll bust the most common engine detailing myths and give you the facts so you can detail with confidence.
Myth #1: “You Should Never Wash Your Engine”
This is the most common myth. People believe water and engines don’t mix. The truth? Modern engines are built with seals and covers to handle splashes. As long as you avoid blasting electrical components with high pressure, washing your engine is safe.
Myth #2: “You’ll Ruin Electronics with Soap”
Harsh degreasers can damage plastics and seals, yes. But safe soaps like The Super Soaper are designed to clean without harm. Electronics are far more protected today than in the past.
Myth #3: “You Must Cover Everything in Plastic”
Some guides recommend bagging alternators, fuse boxes, or batteries. While this isn’t harmful, it’s usually unnecessary. Modern cars can handle light rinsing if you use the right technique.
Myth #4: “Pressure Washing Always Destroys Engines”
Pressure washing can cause damage if misused. But with a wide-angle nozzle (40°), low pressure, and proper distance, it’s safe. See our post on safe pressure washing for details.
Myth #5: “Engine Detailing Takes Hours”
While deep cleans can take 45+ minutes, you can do a quick 15-minute refresh that makes your bay look great. You don’t need hours every time.
Myth #6: “Any Soap or Degreaser Works”
Wrong. Household cleaners, dish soap, or harsh degreasers can damage plastics and hoses. Always use a dedicated car soap like The Super Soaper.
Myth #7: “You Don’t Need to Dry the Engine”
One of the most dangerous myths. Leaving water behind leads to corrosion and electrical issues. Always dry with a blower or a towel like the Massive Drying Towel.
Myth #8: “Dressings Make Plastics Too Slippery”
Cheap, greasy dressings can make plastics slick. But water-based products like All Dressed Up provide a matte OEM finish without grease or dust attraction.
Myth #9: “Engine Bay Cleaning Isn’t Necessary”
Another big myth. A clean engine bay makes it easier to spot leaks, extends component life, and even increases resale value. Neglecting it can cost you more in repairs down the line.
How to Clean an Engine Safely (Fact, Not Myth)
- Pre-soak with The Super Soaper using a foam cannon or pump sprayer.
- Agitate with soft brushes where needed.
- Rinse on low pressure — never blast electricals.
- Dry thoroughly with a blower and microfiber towel.
- Dress plastics with All Dressed Up for protection and a clean look.
