Fleet Wash Chemicals Guide: Degreasers, Power Wash & Protection

When operating a commercial fleet, you deal with road grime, traces of diesel, and salt corrosion on a daily basis throughout the seasons. Routine truck wash soaps are ineffective against the heavy layers of grime and road salts on fleet vehicles. This is when specialized washing products and soaps are needed.

Whether you have delivery trucks operating in Colorado, tractor-trailers on the highways in Virginia, or construction vehicles in Missouri, having knowledge and understanding of professional wash products is worth considering, as it adds value to your business. The proper use of industrial washing soaps and fleet cleaning products prolongs the life of your assets, maintains their good looks, and protects against expensive corrosion repair.

This guide will briefly explain the three categories of products every fleet manager should know about: how protective washing products work, cleaning products for power washing, and commercial-grade industrial degreasers.

Understanding Industrial Degreasers for Fleet Applications

When it comes to oil and the inescapable grime build-up of road dirt, due to the films formed on the surface, a standard detergent will not work. The automotive degreaser works due to its chemical reaction with the surface to break the bonds of the oil and grime layers and thus, after a rinse, will wash away the residue.

How Degreasers Work

Surfactants and alkaline compounds are used to emulsify hostile agents in petroleum deposits. The formulation has been designed to ensure that when you use these products, you’re able to remove grime without damaging the surface (paint, chrome, and rubber seals) of the vehicles.

Here are a few of the Advanced Degreaser’s attributes:

• Extreme alkalinity for cutting through the heaviest of oils.
• Surfactant blends that stop redepositing during the rinsing step.
• Safe Detergent Dilution Ratios that clean effectively while remaining safe.
• Low-foaming for use in pressure washer systems.

Purple Degreaser

One of the greatest and most unique products on the market is called Purile. Purple products are also of the degreaser. Purple products represent an entire line in the commercial cleaning world. Purple cleaning products are known for the effective removal of

• Engine Compartment (grease and dirt)
• Contaminated hydraulic fluid
• Wheel wells (grease)
• Fifth wheel grease

In the Southeast, particularly in Alabama and Georgia, fleets need the powerful, aggressive Purile products because of high temperatures and humidity that quickly accumulate dirt and grease on vehicles.

Degreasing Agents: Maximizing the Efficiency of a Power Washer

Having a pressure washer alone does not guarantee that the fleet is clean. It completely depends on what we are using the cleaning chemical for to guarantee that the vehicles are not coming out just wet.

Choosing the Correct Chemicals for Power Washing

Top-of-the-line power washing cleaners can be grouped into three categories based on how they are applied:

Pre-soak solutions Soften dirt and road film prior to the main washing cycle. These low-pH and alkaline blends require a certain amount of time to work efficiently.

High-pressure washing detergents create foam that lathers on vertical surfaces, allowing for prolonged contact and washing.

Rinse aids and spot-free solutions eliminate spotting and minerals that are left on a surface, which can be critical in low-quality/high-hardness water.

Application Best Practices

Cleaning with chemicals efficiently takes a bit more work than just spraying and hoping for the best. Temperature, along with the dilution ratio and contact time, all affect how well the chemicals work.

Most commercial-grade cleaning chemicals work best if:

• The water temperature is between 110 and 140°F.
• The dilution is done according to the manufacturer’s instructions.
• The pre-soak is left to dwell for about 3-5 minutes before agitation.
• The rinse is done before the products dry on the surfaces.

Fleet managers that are able to get these variables just right see more consistent cleaning results and are able to use less product on each vehicle.

Salt Corrosion Protection: Defending Your Fleet Investment

Winter operations in northern states create the perfect storm for accelerated vehicle deterioration. Road salt, brine solutions, and magnesium chloride treatments attack metal surfaces relentlessly.

The True Cost of Salt Damage

Corrosion doesn’t just affect appearance—it compromises structural integrity, degrades electrical connections, and accelerates component failure. Undercarriage damage often goes unnoticed until repair costs become significant.

Effective salt corrosion protection requires a two-phase approach:

Removal: Specialized wash products designed to neutralize chloride compounds and flush them from crevices where standard washing misses.

Protection: Barrier coatings and inhibitors that create a defensive layer against future salt contact.

Building a Corrosion Prevention Protocol

Operations in Virginia, Missouri, Colorado, and other states with significant winter weather exposure benefit from structured prevention programmes:

• Weekly undercarriage washing during salt season.
• Quarterly protective coating applications.
• Annual inspections of vulnerable areas, including frame rails, brake lines, and electrical connections.
• Immediate washing after heavy salt exposure events.

The investment in proper protection products pays dividends through extended vehicle service life and reduced unplanned maintenance.
