The cleaning car engine is an intricate part of any vehicle. Some people find car maintenance confusing, scared and unpleasant.

But, truthfully, car care is a necessity. Not only do you need to make sure that your car is working at its best, but you also need to make sure that your car is protected from any potential damages.

It also has a high risk of getting clogged and dirty. If you don’t pay proper attention to it, you could face a breakdown anytime soon. This blog will help you know is it safe to clean a car engine?

Let the car cool

If the engine is hot, let the car cool off for fifteen minutes before spraying it with water.

Hot engine components not only burn you upon contact but will also crack or break if they are exposed to severe temperature change that happens when you pour cold water on them.

Remove all plastic parts under the hood

Remove all plastic parts under the hood. Simply scrub them separately. Also, remove the negative terminal from the car battery before you head out to protect electrical components if they get drenched unexpectedly.

Or, remove the battery completely. You might even want to do that if you don’t want to worry about any leakage issues in your engine bay area or trunk area.

It might seem silly not having a battery at hand but we’ve done many a clean-up project without it and haven’t had any problems with cars starting just fine!

Remove all plastic parts under the hood

Use plastic bags

Use plastic bags to cover sensitive parts of your engine. That includes the battery, ignition wires, and engine control unit, as well as any exposed engine air intake under the hood.

If you feel like you’ll be particularly careful with your rinsing, then you can skip this step, but protecting these electronics will allow you to clean more thoroughly with less risk of damaging anything.

Take a degreaser solution

Start with a power wash to spray off the top surfaces. After you’ve allowed ample time for the surface water from the power washing to dry up (a 1-hour window), take a degreaser solution and spray down each component of the engine.

Any type of household cleaner will do, just make sure it dissolves oil and grease based on our experience using Simple Green that comes in a concentrated formula.

We recommend spraying liberally around all components such as underhood components and along the chassis points that might have been missed while being hosed off with water.

Take a degreaser solution

Using a power washer

Using a power washer can be useful, but so can just use a regular hose. Whatever you do, try not to directly spray too close to electrical components and make sure to prevent spraying areas that won’t dry easily.

Be careful with the nozzle! Your car’s casing may look clean on the outside, but there are lots of places for dirt and grime to hide. You don’t want your windshield wipers getting stuck right after using them!

Using a power washer

Dry access water

If you happen to have access to any compressed air, then this will help to dry anything out with ease and maybe improve how things look in the process.

You can also get a shop towel or rag wet and use that to wipe off loose dirt and grime on any areas of the boot that have been affected by water.

By doing so you can remove excess moisture as well as any possible dirt that has built upon the boots themselves over time.

FAQs Related to is it safe to clean a car engine?

Is it safe to spray your engine with water?

From a safety standpoint, it’s generally safe to spray your engine bay with water. Avoid sprayed water carrying too much pressure in areas that contain expensive or sensitive equipment like the alternator, intake, and sensors. Otherwise, you should be fine so long as you don’t knock anything out of alignment. 

Can an engine be cleaned out?

We recommend using a high-grade degreaser. Although there are many degreasers on the market, not all of them can completely rid your engine of grime and grease. Be sure to choose a formula that is eco-friendly to keep our environment clean.

We recommend Simple Green Detergent as it has been proven to be quite effective in cleaning engines, removing dirt and grime from their insides, and leaving them smelling wonderful! 

Should I clean my engine?

We recommend you tune up your engine at least once a year or every 6 months if you drive in areas with dusty conditions.

My car’s running just fine!”. Well, that’s great. But when the time comes for an important road trip or family vacation how will things go if your car breaks down far from home?

Having a well-maintained engine is essential when it comes to reaching your destination and not missing out on anything life has to offer.

Is it OK to power wash your engine?

Yes, using the dishwasher isn’t recommended. But if you have no other option, then there’s one thing you need to remember and that is that any electrical parts of your car should be wrapped first in waterproof plastic wrap/bags to avoid damage caused by water.

Additionally, all airflow systems should also be protected. It’s possible but we strongly suggest that you protect any electrical components by either covering them in plastic bags or something similar because we don’t want to be liable for any damages.

Is steam cleaning badly for engines?

Engine steam cleaning is the latest in engine care technology. This process uses high-pressure, usually, heated water to remove grease, oil, and dirt from the surface of your engine and engine area.

When done properly with the proper safety precautions employed, steam cleaning is 100% safe for your car’s moving parts. ​

Steam cleaning does not use any chemicals – just water at a temperature that never gets above 212ºF (100ºC). It’s completely natural – just plain old H2O!

Conclusion

A car’s engine is a very sensitive piece of machinery. You need to be careful when cleaning your engine, especially when using automotive cleaning chemicals.

The chemicals can be very harsh on your engine’s sensitive parts, and they can even cause damage if you don’t know what you’re doing.

Your engine is most vulnerable during the start-up phase because this is when it’s most exposed to the elements.
