The frequency of an undercarriage car wash depends on several factors, including your local climate, driving conditions, and whether you live in an area prone to road salt, mud, or excessive moisture. Here are some guidelines to help you determine how often to clean your vehicle’s undercarriage:
If you live in regions with harsh winters where road salt is used to prevent ice, it’s important to clean your car’s undercarriage regularly, ideally once a month during winter months. Salt can accelerate rust and corrosion, making regular undercarriage washing essential for long-term vehicle health.
If you frequently drive on unpaved or gravel roads, the undercarriage of your car is exposed to dirt, debris, and mud. In such cases, it’s recommended to clean your vehicle’s underbody every couple of weeks to avoid dirt buildup and preserve critical components like the suspension system and brake lines.
For cars that operate in humid, coastal, or rainy areas, frequent exposure to moisture can lead to rust if not properly maintained. An undercarriage wash should be done monthly or after heavy rainfall to remove water, debris, and contaminants that may cause corrosion.
If you mainly drive on clean, paved roads in dry climates, an undercarriage wash every 3 to 6 months should suffice. However, if you notice significant buildup of grime or dirt, more frequent cleaning may be required.
In general, monthly to quarterly undercarriage washing is ideal for maintaining your vehicle’s longevity and protecting it from the elements.

An underbody wash is an essential feature of modern automatic car washes, designed to clean the underside of vehicles, removing dirt, salt, and debris that can cause rust and corrosion. Here’s a step-by-step guide on how to properly incorporate and use an underbody wash in your automatic car wash:
Before using an underbody wash, make sure that the underbody wash system is correctly installed in your car wash setup. This typically involves mounting underbody spray nozzles along the wash bay, which will direct high-pressure water under the vehicle during the wash cycle.
Position the nozzles to ensure complete coverage of the vehicle’s undercarriage.
The nozzles should be placed low enough to clean the underbody without damaging sensitive parts like the exhaust or brake lines.
Ensure that the system is connected to a water source with sufficient pressure to clean effectively.
The underbody wash system uses high-pressure water to blast dirt and debris from the vehicle’s undercarriage. Ensure that the water pressure is set correctly to avoid damaging delicate parts of the vehicle while still being strong enough to remove tough grime.
Pressure Settings: Check that the pressure is strong enough to clean effectively but not so powerful that it causes harm to the vehicle’s components. Typically, a pressure of 1200-1500 psi is ideal for most automatic car wash systems.
Water Temperature: Some systems can use warm water to help break down grease or sticky substances. Check if your system supports temperature adjustment.
In an automatic car wash, the underbody wash usually happens after the vehicle enters the wash tunnel but before the exterior is cleaned. This ensures that any dirt or debris under the vehicle is loosened and removed before the vehicle’s body is washed.
Pre-Wash Phase: The vehicle is typically sprayed with water to loosen dirt and grime.
Underbody Spray: The underbody wash system activates, spraying the vehicle’s undercarriage from below with high-pressure water.
Exterior Wash: After the underbody wash, the vehicle proceeds to the exterior wash section, where soap, brushes, and rinse cycles are applied.
Ensure that the underbody wash nozzles are spraying evenly across the entire undercarriage. Some advanced systems may use rotating nozzles or multiple spray angles to ensure thorough coverage. It’s essential that the water reaches critical areas, such as the frame, suspension, wheel wells, and exhaust system, where debris can accumulate.
Effective Coverage: Ensure the spray reaches all corners and hard-to-reach areas under the vehicle.
Even Distribution: Make sure the spray nozzles distribute water uniformly along the undercarriage.
After the underbody wash, consider offering additional treatments like rust inhibitors, underbody sealants, or protective coatings as an optional add-on service. These treatments help protect the undercarriage from corrosion and extend the life of the vehicle’s components.
Rust Prevention: Apply a protective coating that helps prevent rust from forming on exposed underbody parts.
Underbody Sealant: This can protect metal parts from exposure to water, salt, and grime, reducing long-term wear and corrosion.
To ensure the underbody wash system is functioning at its best, regular maintenance is key. Check for clogs, damage, and water pressure issues to prevent poor performance.
Clean nozzles to prevent clogging from mineral buildup or debris.
Inspect hoses and connections for leaks or wear.
Periodically test the system to ensure the pressure and water flow are consistent.
Washing under a car itself doesn’t directly cause rust, but the way it’s done can influence the likelihood of rust formation. Here’s why:
Water Traps: If water is allowed to pool in certain areas under the car (like around the wheel wells, exhaust system, or undercarriage), it can promote rust. Water sitting in these spots for long periods can cause corrosion, especially in areas where there’s already some wear or damage to the paint or coating.
Use of High Pressure: Using a high-pressure wash under the car can potentially dislodge protective coatings, or cause water to get into places that are difficult to dry, such as inside body seams or under fenders. This can increase the chances of rusting if moisture is trapped and not dried properly.
Salt and Debris: In regions where road salt is used during winter, washing under the car is essential to remove salt and prevent rust. However, if salt or other debris is left on the undercarriage and not washed off thoroughly, it can accelerate rust formation.
Exposure to Humidity: If the car is washed under wet conditions but isn’t dried quickly (especially if stored in humid areas), the moisture can remain and cause rust over time.
To minimize rust risk, it’s a good idea to rinse the undercarriage well, use rust-resistant coatings, and ensure the car is fully dried after a wash. Regular cleaning and maintenance of the undercarriage are key to preventing rust buildup.
