Step by step: How to wash the undercarriage of a car?

Washing the undercarriage of your car is an important step in the maintenance process. It not only provides an aesthetic appearance, but also eliminates dirt, road salt and other factors that may accelerate corrosion. Here is a step-by-step guide on how to properly wash the undercarriage of your vehicle:

1. Prepare and secure your car.

Wear protective gloves and goggles to protect your hands and eyes from chemicals.

Make sure the car is placed on a flat and stable surface. If you use a car jack, check that it is properly attached.

Allow the engine to cool down to avoid burns.

2. Start by washing the wheels.

Before you start washing the undercarriage, start with the wheels. Use special rim cleaner and tires to remove brake deposits, mud and dirt.

3. Remove large dirt.

Using a garden hose with a washing gun or pressurized water, rinse visible dirt and mud from the bottom of the car.

4. Apply a cleaning agent.

Choose the appropriate cleaning agent intended for washing the undercarriage. It may be a special underbody cleaner or degreaser.

Apply the cleaner to the undercarriage, focusing on areas where you see corrosion, rust or stubborn dirt. Remember that some cleaning products can be aggressive, so use them according to the manufacturer's instructions.

5. Wait for the cleaning agent to work.

Let the cleaner work for a few minutes. This will enable it to dissolve dirt and deposits.

6. Use a brush or brush.

To thoroughly clean hard-to-reach places and areas covered with a thick layer of dirt, use a brush or brush. Gently scrub areas that need extra attention.
