Can I put my car through an automated car wash?

Quick answer: Best avoided - brush car washes can mark paint and coatings. If you must, choose a touchless programme and rely on proper hand-wash methods for regular cleaning.

There are some automated car washes that are safe to use, but most aren't.

We generally don't recommend it. It very much depends on the type of car wash. The older types have brushes which are plastic bristles like a garden broom, which are really no good for your car. Newer types are 'Soft Wash' and are less like a broom and more like a mop. These are far better if maintained in good condition. If they are old, however, the mops can be caked in soap scum and grit. Either way, an automated car wash is not the ideal way to clean your car in the long term.

The exception are touchless car washes which are ideal for cars with ceramic coatings, on the proviso that they are maintained correctly and not using very caustic soaps, which is something some outlets are prone to do as it allows them to speed up the machine, meaning they can wash more cars in a day and make more money. (The same goes for many hand car washes).

No car wash cleans your car perfectly and there is no substitute for a hand wash, which we recommend you do once in a while to get all the bits a car wash can't reach.

What this question is really about

This isn’t just about convenience. It’s about whether an automated wash will damage the paint, reduce the life of a ceramic coating, or undo previous correction work.

There are two very different types of automated wash

1. Brush (contact) washes

These use rotating brushes or hanging strips that physically touch the paint. Even if they look soft, they are used on hundreds of vehicles and can hold grit.

  • High risk of swirl marks and wash marring.
  • Can dull the finish over time.
  • Can shorten the effective life of a ceramic coating.

2. Touchless (no-contact) washes

These rely on pressure and chemicals rather than brushes.

  • Lower risk of mechanical scratching.
  • Stronger chemicals are often used to compensate for no contact.
  • Frequent use of harsh chemistry can reduce coating performance.

If your car is ceramic coated

A coating helps reduce wash marring, but it does not make brush washes safe. Repeated brush washing will still introduce defects and may require machine polishing - which removes the coating in the corrected areas.

If you have no alternative

  • Choose touchless over brushed.
  • Pre-rinse thoroughly if possible.
  • Avoid the “wheel acid” or harsh add-ons unless needed.
  • Wash properly at home when you can to reset the surface.

The long-term view

If you’ve invested in paint correction or ceramic coating, regular brush washes are the quickest way to undo that investment. Occasional use won’t destroy the car - but frequent use will gradually dull and mark the finish.

What you should ask next

Will one trip through a brush wash ruin my car?

One visit won’t destroy the paint, but it can introduce light wash marks. The damage is cumulative - repeated use is what gradually dulls the finish.

Are touchless car washes completely safe for ceramic coatings?

They are safer mechanically, but frequent use of strong chemicals can reduce hydrophobic performance over time. Occasional use is usually fine.

Why do coatings still get swirl marks in brush washes?

Because coatings are thin. They help resist light marring, but they are not scratch-proof. Grit in rotating brushes can still mark the surface.

If a brush wash marks my coating, what fixes it?

Machine polishing will remove the marks - and the coating in that area. The affected panels will then need to be re-coated.

What’s the safest fast option if I’m short on time?

A self-serve jet wash where you can pre-rinse thoroughly and avoid contact brushes is usually the safest quick solution.
