You will need some mechanical tools for this rugged job. A toolbox should contain everything. Take those tools out of the market if you are missing something.

  • Car Jack
  • Hosepipe
  • Wrench
  • Undercarriage Cleaner
  • Pressure Washer

Once all these things have been arranged, we can move forward.

Take some hot water and white vinegar and mix them in the same proportion if you don’t want to buy a special car wash soap for your car undercarriage. You now have a homemade wash solution on your hands.

To begin cleaning, let’s go through these steps:

Step One

You should remove the wheels first in the process. The wheels of your car tend to be most affected by road salt which creates rampant damage to your car over time.

Although some people don’t want to go through such trouble, you should be cautious as wheels are most susceptible to salt. It’s time to bolt out the wheels, so grab your jack and wrench.

As we cannot see the underside of the car, the next step is to lift it. Hold the jack still and lift it up. A vehicle should be positioned at a level where you can easily see through it and work on it.

It is strongly recommended that you do not go under the car without taking adequate protective measures. The consequences of one minor accident can be fatal.

Step Two

Taking out the wheels and lifting the car were quite heavy jobs. Now it’s time to get to the point. Those disturbing salts need to be washed away.

Hosepipes should be connected to pressure washers. Release the pressure under the vehicle. The area beneath your car should be divided into several sections in your mind. This will make it easier to clean.

You will need to use maximum pressure when washing away the salts from their homes. Make sure the washer is held at a 45-degree, this angle is supposed to maximize pressure.

Once the area has been cleaned thoroughly, go back to the previous portion.

Step Three

It is unlikely that you will completely remove all the salt and rubbish with the pressure washer. However, you will still find some salt. It will take more than water pressure to remove that little pile of salt.

Now that you have prepared the wash solution, it’s time to use it. Scrub the remaining salt with a brush after you’ve sprayed it on.

It is advised that you repeat the procedure multiple times.

Step Four

Undercarriage cleaner should be used now. These cleaners, unlike our hand and pressure washers, spray water over a wide area and clean areas that are difficult to access with our hands or pressure washers. Wash it several times with it.

There is an end to this troublesome task. The engine block or any internal part of the car should not get wet during any of the work you do. Whenever working with a cloth, it is best to cover all the ways before starting.
