Yes, but it's generally not recommended and requires extreme caution. The high-pressure water jets and abrasive brushes in an automatic car wash can easily damage the soft top's fabric or vinyl material, compromise the seals, and lead to costly leaks. The safest method for cleaning a soft top convertible is always a gentle hand wash.
The primary risk lies in the intensity of automatic car washes. The concentrated water jets can force water past the top seals (the rubber gaskets that keep the cabin watertight), even if they appear intact. Over time, this pressure can degrade the seals and the fabric itself. Furthermore, the large spinning brushes can snag on loose threads or seams, causing tears. If you absolutely must use an automatic car wash, choose a touchless facility that uses only high-pressure water and soap, and avoid any option with cloth brushes.
For a proper wash, here’s a better approach:
| Potential Risk | Consequence | Safer Alternative |
|---|---|---|
| High-Pressure Jets | Force water past seals, causing interior leaks. | Use a touchless car wash or hand wash with low pressure. |
| Abrasive Brushes | Snag and tear the fabric or vinyl material. | Clean manually with a soft bristle brush. |
| Harsh Chemicals | Fade or degrade the top's material over time. | Use pH-neutral, convertible-specific cleaning products. |
| Inadequate Drying | Promotes mold and mildew growth on the fabric. | Dry thoroughly with a microfiber towel or air dry in the sun. |
| Wear on Seals | Accelerates aging of rubber seals, reducing lifespan. | Regular inspection and application of rubber protectant. |
Ultimately, the few minutes saved by an automatic car wash aren't worth the potential for hundreds or thousands of dollars in repair bills for a new soft top or water damage remediation.

















I'd never take my Miata through a regular car wash. Those big spinning brushes are terrifying. I hand wash it every time. It's a bit more work, but I use a special cleaner for the canvas top and a separate protectant spray. It keeps the water beading up like new. The peace of mind is worth the extra twenty minutes on a Saturday morning. It's just part of owning a convertible—you gotta take care of the top.

Consulting your owner's manual is the most authoritative step. Most manufacturers explicitly advise against automatic car washes for soft tops. The manual will outline the approved cleaning methods, which almost always specify gentle, hand-washing techniques. Following these guidelines protects your top's warranty and ensures you're using products that won't damage the specialized materials. This isn't just a suggestion; it's the official instruction for maintaining the vehicle's integrity.

It's a calculated risk. If the car is a daily driver and the top is in good shape, a modern touchless car wash is probably okay occasionally. The key is avoiding any physical contact. But you have to accept that even touchless systems use very strong water pressure, which might find a weak spot in a seal. It's a convenience trade-off. For a classic car or a convertible with a pristine top, I wouldn't even consider it. Hand washing is the only way to guarantee no harm is done.

Think of it like washing a good leather jacket. You wouldn't throw it in a machine with agitators, right? A soft top is similar; it's a specialized material that needs gentle care. The automatic car wash is designed for the hard, sealed surfaces of a regular car roof. Your convertible's top is its most vulnerable point. Taking the time to hand wash it isn't just about cleaning; it's preventative that extends its life and keeps you dry during the next surprise rain shower.
