Can Hard Car Wash Chemicals Destroy Your Expensive Ceramic Coating?

You finally did it. You spent your hard-earned money on a premium ceramic coating. Your car looks like it's made of liquid glass, and water rolls off it like magic. But a few months later, after taking it to a local roadside car wash, you notice the shine is fading and the water isn't beading up anymore.

What happened? Did the coating fail? Probably not. The culprit is almost certainly the harsh chemicals used during the wash.

The Truth About Local Car Wash Soaps

Many cheap, high-volume car washes prioritize speed and cost over safety. To dissolve tough grime and grease quickly without scrubbing, they use highly alkaline (high pH) or highly acidic (low pH) industrial detergents. Sometimes, they even use dish soap.

While ceramic coatings are highly chemical resistant—far more so than traditional waxes—they are not invincible. Repeated exposure to extreme pH chemicals will degrade the hydrophobic top layer of the coating, causing it to lose its water-repellent properties and brilliant gloss prematurely.

How to Wash a Ceramic Coated Car Safely

Maintaining a ceramic coating requires a gentle touch. The entire point of the coating is that dirt doesn't stick to it easily, so you don't need harsh degreasers to clean it.

• Always Use pH-Neutral Shampoo: Look for car wash soaps specifically labeled as "pH-neutral." These will safely lift dirt without attacking the coating's structure.
• Avoid Automated Brush Washes: The spinning brushes at gas station washes harbor dirt from previous cars and will inflict micro-scratches on your coating.
• Use the Two-Bucket Method: If washing at home, use one bucket for soapy water and one for rinsing your mitt, so you aren't rubbing dirt back onto the paint.
