Driver Tries To Wash Tesla. Why Is The Water Doing That?
When it comes to hand-washing or using a self-serve bay, Tesla recommends a cautious approach.
Call it a case of car wash confusion. In a viral TikTok clip, Tesla owner Sedgefieldsunshine (@sedgefieldsunshine) pulled into a self-serve wash bay, sprayed down their Tesla, and was left scratching their head. Instead of soaking in, the water seemed to scatter and slide away. “What’s going on with my car when I wash it?” they asked TikTok, sparking a flood of theories.
In the comments, suggestions ranged from “wash mode” to ceramic coating. The creator clarified there was no ceramic coating—just a spray polish. That detail became central: the hydrophobic water behavior came from an applied spray, not a hidden Tesla feature.
For Tesla owners asking a common question—“How do I wash a Tesla?”—the clip was short on best practices, things to avoid and guidance on how Tesla recommends it be done.
Tesla’s Official Washing Guidelines
According to Tesla’s owner’s manual, exterior cleaning should be done using mild, pH-neutral soap (a good car shampoo), clean soft cloths or sponges, and water that is cold or lukewarm. Harsh chemicals or high-alkaline or caustic cleaners are discouraged.
Tesla provides a Car Wash Mode feature. When engaged, this closes or locks windows and the charge port, disables the wipers, and may silence warning chimes, all so the vehicle is safely prepared for cleaning. It’s intended to avoid damage to sensitive components during automatic or self-serve washes.

Tesla also cautions about using pressure washers: Keep the nozzle at a safe distance (often ~30 cm or 12 inches); avoid directing spray toward seals, sensors, cameras or exposed trim or electronic modules; and never aim high-velocity water at these components, especially while the vehicle is charging.

When it comes to hand-washing or using a self-serve bay, Tesla recommends a cautious approach. The company advises starting with a rinse to remove loose debris like dirt or bird droppings that could scratch the paint if rubbed in. Owners should also make sure windows and the charge port are fully closed and enable Car Wash Mode, if available, to lock settings, disable wipers, and close sensitive openings to prevent issues during the wash. For cleaning, Tesla specifies using a mild, pH-neutral car shampoo rather than strongly alkaline soaps, and applying it with microfiber cloths, mitts, or soft sponges rather than brushes that might hold grit.
Technique matters as well. It’s best to work top to bottom so dirt naturally flows downward, rinsing as you go. After rinsing off all soap, drying with microfiber towels is important to avoid water spots, something Tesla notes explicitly in its guidance. For those who want an extra layer of shine and protection, sprays, waxes or even ceramic coatings can enhance water beading. However, sprays like the one shown in the viral TikTok are temporary solutions rather than long-term paint protection.
Exercising Caution
Tesla owners are often warned to steer clear of automatic car washes that rely on brushes or rough rollers. Many drivers report that these can leave scratches or swirl marks on paint and trim, especially given Tesla’s sometimes softer paint finishes. High-pressure water jets can also cause problems if directed too closely at seals, sensors, cameras, or the charge port, where the force of the spray risks pushing water into places it doesn’t belong. Similarly, Tesla cautions against using harsh chemical cleaners or soaps that aren’t pH-balanced, since these can dull paint or degrade protective coatings over time.
Other common mistakes include washing in direct sunlight or letting soap dry on panels, both of which can leave streaks and water spots. It’s also easy to overlook the underside, wheel wells, and lower trim, though Tesla recommends rinsing these thoroughly, especially for drivers in areas with road salt or heavy debris.
In the viral car-wash clip, the unusual water behavior wasn’t a hidden Tesla feature but the effect of a spray polish, something the creator eventually confirmed. That distinction underscores a few lessons for EV owners: protective sprays and detailers can create dramatic hydrophobic effects even without ceramic coating; water beading doesn’t mean a car is protected by factory tech; and the method you choose can make a big difference in preserving paint over the long run.
Ultimately, washing a Tesla isn’t complicated, but it does require care: Use pH-neutral soap and microfiber cloths instead of brushes, keep pressure washers at a safe distance, enable Car Wash Mode when available and dry thoroughly. As the TikTok showed, sometimes what looks like magic is simply the right mix of physics, chemistry and product choice.
