Cleaning an Engine Bay: What You Must Not Spray
The videos hose it down and cut before the restart. This page is written the other way round: what must not get wet, and why the damage is often delayed.

AAA says about every two weeks. Consumer Reports says monthly in snow season. Its own how-to page publishes no interval at all. What that disagreement means.
Wheels go first, and the reason is dwell time. But the thing that actually protects your paint is separate tools and separate water, not the sequence.
Bug remains are acidic and etch clear coat the longer they sit. Soak, dwell, and never scrub dry. The order that actually protects the paint.
Snow foam loosens grit before contact, which genuinely helps on a dirty car. On a lightly dusty one, a thorough rinse does most of the same job.
Unlimited plans pay off around two to three washes a month, but the real question is what equipment your money buys, not just the math.
Touchless avoids contact but leans on stronger chemistry. Hand wash is gentle only if the technique is right. The honest trade-off, not a winner.
No driveway, no spigot, and rules about the parking lot. Rinseless and waterless washing explained, plus their real limits and lot etiquette.
Rinseless carries the rinse’s lubricating job inside the solution instead of a hose. What that means for how dirty is too dirty, and when it fits.
It is not the sun itself. A hot panel dries water and shampoo before you can rinse it away, and that is what leaves the spots and streaks.
