The short answer is: it depends. It depends on the type of carwash and the condition of your engine. Modern carwashes are designed primarily for cleaning the exterior of your vehicle. They are not typically equipped to safely and effectively clean an engine bay.
Washing your engine at a standard carwash can potentially cause significant damage. High-pressure water can force its way into sensitive electrical components. This can lead to short circuits and other malfunctions; Furthermore, the detergents used in carwashes may not be suitable for engine components. They can damage rubber hoses and plastic parts.
FAQ: Washing Your Car Engine
Is it ever safe to wash my engine at a carwash?

What are the risks of washing my engine?
- Electrical damage: Water can short-circuit sensitive electronics.
- Corrosion: Water can accelerate rust and corrosion.
- Damage to components: High pressure can damage hoses and seals.
What’s the best way to clean my car engine?

A detail brush can help you reach tight spots. It’s a slow process, but it minimizes the risk of damage. It is a very important task to do carefully.
What if my engine is really dirty?

Further Considerations for Engine Cleaning
So, you’ve decided to clean your engine. But are you truly prepared? Have you gathered all the necessary supplies? Do you have the right degreaser for your engine type? Are you aware of the potential environmental impact of your cleaning products? Have you considered using biodegradable options? And what about proper disposal of used cleaning materials? Are you planning to protect your driveway from oil and grime runoff? Have you laid down a tarp or absorbent material? And most importantly, are you absolutely sure you know what you’re doing? Are you confident you won’t damage any sensitive components? Perhaps a second look at the owner’s manual is in order? Or maybe a quick consultation with a trusted mechanic? Wouldn’t that give you some peace of mind?
What about cleaning the engine bay plastics?
Are you planning on cleaning the plastic components in your engine bay? Do you know which products are safe to use on plastic? Will you be using a dedicated plastic cleaner and protectant? Are you aware that some cleaners can cause discoloration or damage to certain types of plastic? And what about the rubber hoses? Are you going to inspect them for cracks or wear? Will you be replacing any hoses that are showing signs of damage? Isn’t preventative maintenance always a good idea?
And the engine cover?
Does your engine have a decorative cover? Are you going to remove it for cleaning? Do you know how to remove it without breaking any clips or fasteners? Will you be cleaning the cover separately? And what about the underside of the cover? Is it also covered in grime? Will you be using a different cleaning product for the cover than you use for the engine itself? Is it worth the effort to make it look brand new?
What about drying the engine?
After cleaning, how will you dry the engine? Are you going to use compressed air to blow out any water from hard-to-reach areas? Will you be using a clean, lint-free cloth to wipe down the surfaces? Are you going to let the engine air dry completely before starting it? Or are you going to risk starting it with moisture still present? Wouldn’t that potentially cause problems? And what about applying a protectant after drying? Will you be using a product to protect the engine from future corrosion? Isn’t that a worthwhile investment?
