can duallys go through car wash

[DiLukas]

Yes, most modern dually trucks can safely go through a car wash, but it is absolutely critical to choose the right type of wash. The primary concern is the vehicle's width. A standard dually pickup has a wider rear axle and fender flares that can be damaged by the rigid, spinning brushes in a traditional automatic friction car wash. The safest and most recommended option is a touchless or brushless automatic car wash, which uses only high-pressure water and detergents. You should also be mindful of any aftermarket modifications, like tall radio antennas or roof-mounted cargo racks, that could snag or hit equipment.

Before entering any automatic wash, it's wise to check the width limit posted at the entrance. While most commercial car washes can accommodate a dually's width (typically around 96-98 inches at the mirrors), some older or smaller tunnels may not. For ultimate control and to eliminate any risk of damage, a self-service bay where you hand-wash the vehicle is your best bet. This allows you to carefully clean the intricate wheels and long body. If you do opt for an automated wash, always fold in your side mirrors as a precaution.

Car Wash Type	Suitability for Dually Trucks	Key Considerations
Touchless Automatic	Excellent	Uses high-pressure water and chemicals only; no physical contact eliminates risk of scratching or damaging fender flares.
Soft-Cloth/Automatic	Use with Caution	Ensure the wash is advertised as "oversized vehicle" capable. Rigid brushes may still pose a risk to mirrors and flares.
Self-Service Bay	Excellent	You control the pressure washer and brush, allowing for a meticulous clean. Best for avoiding all potential damage.
Hand Wash	Ideal	The safest method, though most labor-intensive. Perfect for preserving the truck's paint and finish.
Tunnel Wash with Guides	Risky	The track guides that align your wheels may be too narrow for a dually's wide rear tires, potentially causing alignment issues.

I drive a dually for work, and I only use the touchless bays. The big brush washes make me nervous—I’ve seen them snap off antennas and scratch up paint. With a touchless wash, you just drive in, the jets do all the work, and you drive out. It’s not as perfect as a hand wash, but it’s a quick, safe way to get the salt and grime off without worrying about messing up my truck’s wide stance. I always fold the mirrors in, just to be extra safe.

The main issue is the rear fender flares. They stick out and aren't as sturdy as they look. A spinning brush in a standard automatic car wash can catch them and crack the plastic or, worse, wrench them right off. Always look for a "brush-free" or "touch-free" sign. These washes are designed for exactly this kind of situation. If you're unsure, just take five minutes in a self-service bay. It's cheaper than a thousand-dollar body shop bill for a new set of fender flares.

Check your owner’s manual. Some manufacturers have specific warnings about automatic car washes for their dually models because of the potential for damage to the mirrors and fender flairs. Beyond that, think about your aftermarket stuff. Do you have a lift kit? Bigger tires? A roof rack? All of that changes your truck's clearance and profile. What works for a stock truck might not work for yours. When in doubt, hand wash it. You’ll get a better clean and peace of mind.

I learned this the hard way. I took my new-to-me used dually through a standard brush wash. It seemed fine until I got out and saw deep swirl marks all over the rear fenders from the brushes. The paint was ruined. Now, I either do it myself or go strictly touchless. It’s not just about breaking parts; it’s about preserving your investment. A dually is a big, expensive truck. Treating it right means being picky about how you clean it. That minute you save by using a quick brush wash isn't worth the cosmetic damage.
