The undercarriage is one of the most overlooked areas of a vehicle, yet it takes more abuse than any other part. Constant exposure to road grime, salt, moisture, and debris can leave it looking dirty, faded, and neglected, taking away from the overall appearance of your ride no matter how clean the rest of it may be.

A properly cleaned and conditioned undercarriage not only looks better but also helps protect critical components and completes the detail from the ground up. In this blog, we will cover the products you need and walk you through the proper steps to clean, restore, and protect your vehicle’s undercarriage the right way.

If you are more of a visual learner, this video walks you through the entire undercarriage cleaning and restoration process step by step, showing exactly how to properly clean, condition, and protect the underside of your vehicle.

When it comes to cleaning and conditioning your undercarriage, many people rely on degreasers and tire dressing. While these products may deliver short term results, they are not designed to properly clean, protect, or preserve undercarriage components long term.

Degreasers vs. Solution Multi Purpose Cleaner
Traditional degreasers rely on a high pH to break down grime. While effective, they can be overly aggressive and may stain or damage aftermarket components such as billet aluminum, powder coated parts, or anodized finishes. Solution Multi Purpose Cleaner cleans by emulsifying dirt and buildup rather than burning it away with harsh chemicals. This allows it to clean thoroughly while remaining safe on sensitive and high end undercarriage components.

Tire Dressing vs. Classy Chassis
Tire dressing is often used to add shine under the vehicle, but it breaks down quickly when exposed to water and attracts dust and debris. Classy Chassis is a solvent based formula designed specifically for undercarriage use. It does not wash away with water, lasts for weeks, and creates a protective sacrificial barrier that makes future cleaning easier. It also levels evenly on shocks, control arms, and suspension components without leaving a greasy or tacky residue.

Using the proper products not only improves appearance but also protects your undercarriage and ensures your results last.

Pre rinse the undercarriage thoroughly to flush away loose dirt, mud, and debris before beginning the cleaning process.

Spray Solution Multi Purpose Cleaner directly onto all undercarriage components, using the ready to use formula or a 4:1 dilution from the gallon. Allow the product to dwell for a short period so it can emulsify and lift embedded grime, grease, and road film from the surface without harming sensitive or aftermarket components.
