3 Dos and Don’ts of Effective Car Undercarriage Cleaning

Did you know that cars and trucks will not protect against frostbite? Frostbite and freezing temperatures can be hazardous to your car’s undercarriage. If you live in an area that gets heavy snow, a buildup will lead to serious issues.

There are more reasons to keep your undercarriage clean than winter weather. Dirt and grime build up quickly in this area. Not to mention, the undercarriage usually doesn’t get washed as often as other parts of the car.

Here are a few dos and don’ts to consider when doing a car undercarriage cleaning.

Do’s When Cleaning Car Undercarriage

Vehicle undercarriage cleaning is an important part of proper vehicle maintenance. It helps to avoid corrosion and rust and can help keep your car running smoothly for years to come. Here are some dos to consider for effective and safe car undercarriage cleaning:

1. Pre-Rinse

Prerinse is the first step in effective car undercarriage cleaning. It is important to rinse off as much loose dirt, debris, and salt as possible. The pre-rinse should involve spraying the undercarriage from a distance of approximately three feet and using a lower pressure than is used when washing the vehicle.

2. Inspect for Rust or Damage

It’s important to check all the components, such as suspension, exhaust, and brake system, to identify any risks like rust or potential damage. To assess any existing rust, don’t just brush it off, as it can quickly and easily cause more harm.

3. Use a Soft Brush or Bristle

Harder brushes may damage the metal frame, protective components, and paint. Soft brushes or bristles are better suited to gently dislodging dirt and debris that can cause damage to the car over time. When working around sensitive mechanical components and electrical components, using a soft brush will help ensure that the proper and necessary lubrication is not contaminated or removed. 

Don’ts When Cleaning Car Undercarriage

Some of the common don’ts when cleaning a car undercarriage are using harsh detergents or chemical solvents, which can damage the undercarriage parts. Here are some other things you shouldn’t do if you want to clean your car’s underside well and safely.

1. Ignore Protective Gear

Ignoring the need for protective gear when performing this task can be extremely dangerous. Not only can the dirt and debris thrown up by the pressure washer projectile cause serious injury, but it can also leave scratches and gouges on the car’s undercarriage if not handled correctly.

2. Clean When Hot

Don’t clean the underside right after you drive. When cleaning products are put on hot parts, they can evaporate quickly, making them less effective.

3. Use Wire Brushes

Never clean the underside with wire brushes or other rough things. They can damage surfaces and take off protection coatings, which speeds up the rusting process. You can contact this auto detailer to have the inside and outside of your car cleaned in a more detailed and thorough way.
