Are you paying for undercarriage corrosion?

Whether it’s a company car or a heavy-duty commercial truck, there’s a hidden part of your vehicle and constantly under attack: the underbelly. Why should you care? Because the structural and operational integrity of your undercarriage directly impacts vehicle safety, performance, and even long-term value!  

Unfortunately, in the rush of doing a vehicle wash, it’s commonplace to skip this crucial cleaning step. But when you do, it leaves expensive systems—like the brake lines, suspension, and exhaust—exposed to relentless corrosion. And repair and replacement costs can rapidly climb into the thousands of dollars!

4 Sneaky Undercarriage Corrosives

1. Damage Scratcher

Gravel, rocks, glass and general road debris bounce up into your undercarriage and constantly scrape and chip away at the protective coatings and paint. Once the bare metal is exposed, rust immediately sets in.

2. Sticky Sponge

When they stick to your undercarriage, thick dirt and mud they act like sponges. They trap and hold corrosive elements like moisture, salt and other road chemicals right up against the metal, leading to extremely fast rust spots forming in those areas.

3. Gooey Softener

Oil, grease, and other chemicals you pick up on the road cling to everything, and can rapidly ruin the non-metal parts underneath, causing them to crack or soften and fail early. This includes bushings, rubber seals and plastic wiring insulation.

4. Rust Helper

Driving at the higher elevations where there’s ice and snow? Road salt doesn’t just sit there; it’s an aggressive chemical that makes metal rust much faster. Even worse, the clingy salt takes a long time to break down, waiting for the next bit of water to restart the corrosive process over and over again. If that’s not bad enough, salt actively draws moisture out of the air and holds it tightly against your vehicle’s metal parts, constantly soaking your frame in salt water, making sure the corrosion never gets a chance to stop.
