The undercarriage is a dirty, neglected area of your car. It’s easy to forget about it and neglect it, until you have to crawl underneath your vehicle to change the oil or give it an oil change. But there are many other things that can go wrong with the undercarriage of your car if you don’t regularly wash it off. So let’s get started!

What to look for before you start washing

Now that you’ve cleaned the car, it’s time to wash it. Before you start, there are a few things to consider:

  • The car should be clean and dry. If there is any dirt or oil on the surface of the car, these contaminants will get embedded into the paint after washing and make them difficult to remove. The best way to avoid this is by washing your vehicle as often as possible (daily in hot weather).

  • You’ll also want to check weather conditions before getting started. If it’s raining or too cold outside for long periods of time, it might not be worth using water on your vehicle since it could freeze overnight and cause more damage than good if left untreated over winter months (this isn’t an issue if you live in high-humidity areas like Florida). Another option would be buying an electric pressure washer instead – they’re cheaper than gas-powered ones but still do an effective job at cleaning surfaces without causing damage when used correctly! For those who live near bodies of water where they could hose down their cars instead…well then even better! Just make sure there isn’t any salt residue leftover from winter melts because otherwise its going into everything else too easily which will cause rusting issues later down line so just keep that mind 🙂

How to wash your car’s undercarriage

The most important thing to remember is that the undercarriage of your car should be washed regularly. A clean undercarriage will protect the engine and other vital parts from being damaged by dirt, grime, and rust. It can also help prevent corrosion of your vehicle’s chassis.

To clean your car’s underside, you might use a water broom or pressure washer at the local car wash service. A water broom works by spraying a stream of water underneath your vehicle via high-pressure hoses attached to a trailer hitch adapter on top of your truck or SUV. The pressure washer is another option that uses high-power spray nozzles to blast away dirt and grime from beneath your vehicle with pressurized streams of water at up to 400 PSI (pounds per square inch).

When using these tools to wash undercarriages, it’s important not only that they’re easy-to-use but also safe and effective in removing contaminants without harming paintwork or any other part within reach of their powerful spray nozzles!

Equip your garage with the right cleaning products.

There are many types of undercarriages and each one requires a specific cleaning method. The type of vehicle you drive will determine the appropriate tool to use for washing your car’s undercarriage.

If you have a car, then you will need to purchase a high-pressure hose attachment that can be attached to your existing water pressure washer. This attachment allows the user to apply force from above onto any surface, including water-repelling surfaces like glass windows or painted surfaces (which usually repel dirt). This is important because if there were no way of applying force against these surfaces through gravity alone—or without using chemicals—then they would never get clean!

Prepare your workspace.

Before you begin washing your car, make sure that you have the following:

  • Enough space to work on your car.

  • Enough water to wash your car.

  • Enough soap to wash your car.

  • Enough towels to dry your car.

Get underneath, and spray away grime.

Get underneath, and spray away grime. If you’re using a pressure washer, now would be the time to turn that puppy on and let loose. If not, grab your water broom or spray bottle and get scrubbing! You’ll want to clean all around your undercarriage—underneath the car, inside wheel wells (especially where they meet metal), and anywhere else dirt or grime might have gathered.

Clean the undercarriage with an undercarriage cleaner.

An undercarriage cleaner is a spray that can be used to clean the undercarriage of a car. It is a great way to get rid of any dirt, grime and oil stains that might be stuck on your car’s undercarriage.

When using this type of product, you will want to make sure it is completely dry before driving your car again.

Power wash the wheels.

To clean the wheels, you can use a power washer or a garden hose with a nozzle to spray water. If you choose to use a power washer, set it to low pressure and make sure that you don’t damage the paint by applying too much pressure. The cleaning solution for your wheels will depend on which type of tire cleaner you have chosen:

  • Tire Cleaner with Degreaser: Use this product first because it contains both detergents and degreasers that help remove dirt from tires while also breaking down grime and oil stains.

  • Wheel Cleaner: This is another effective option because it cleans wheels quickly without leaving behind any residue while also protecting against rusting or corrosion.

To clean your car’s undercarriage, get underneath it and spray away grime; then use an undercarriage cleaner, and power wash the wheels.

Start by getting underneath your car with a flashlight to inspect the frame, suspension, brake lines and exhaust pipes. If you see any rust or dirt buildup anywhere along these areas, it should be cleaned off using a wire brush on a long handle (to avoid bent over positions). If you need more power than that, use a steamer to remove hardened grease. If you’re lucky enough to have access to an air compressor or leaf blower at home (or even just some air hose), those will do nicely as well.


There’s nothing more satisfying than a clean car, and it doesn’t have to be hard. With proper preparation and the right tools, your garage can become a great place for cleaning up both your undercarriage and its wheels. Good luck!
