Choosing the right truck wash soap will go a long way to ensuring your fleet stays clean and runs smoothly for years to come. But there are many different types of chemicals in your detergents and soaps. Some consist of corrosive ingredients and it can be important to know if they are safe for your fleet or the people using them.
In this blog, you’ll learn about some of the main ingredients in truck wash cleaning products, why they’re used, and how to know which one is right for your fleet.
Whether you’re a commercial fleet washer or manage your own fleet, understanding which ingredients are in your truck wash soaps is important. Otherwise you run the risk of damaging your truck surface, etching the glass, or just being ineffective.
There are many different chemicals used in your truck wash soaps. But these can be broken down into two main categories:
Every truck wash detergent is measured by either being an acid aka low pH OR as an alkaline aka high pH.
The pH scale ranges from 0 - 14, with a pH level of seven being neutral. Any pH level less than seven is considered acidic. Any pH level above seven means your truck wash detergent is base or alkaline.
Knowing there are acids in your truck wash soaps can feel intimidating. But not all acids are bad. In fact, there are many everyday items that are technically acidic but aren’t harmful; things like coffee or even red meat.
Almost all low pH presoaks are blends of different acids. Small amounts of low pH acids like hydrofluoric (HF), sulfuric, phosphoric, hydrochloric, ammonium bifluoride (ABF), and citric are common ingredients in many truck wash low pH detergents.
That’s because they are highly effective against inorganic materials and minerals like dust, lime, or salt. They are also great for removing discoloration and oxidation from various metals, and brightening the aluminum for the fleet industry.
Here are a few common acids in your truck wash soaps:
Alkalines are on the opposite side of the pH scale to acids. They are used to break down the carbon based soils that are on the vehicle's surface.
They are effective against grease, oils, proteins, and other organic material. Some common alkaline chemicals include:
Butyl is another popular ingredient that can be interjected into an acid or alkaline base product to assist with breaking down oils that are common in our industry on the hoods and driver side doors of trucks. Butyl is a water soluble ingredient found in many high pH alkaline truck wash detergents and degreasers and occasionally added to low pH acidic cleaners.
Road film is a thin layer of dirt, smoke, and other contaminants that get stuck to the surface of your vehicles. It can be extremely difficult to remove, even if you brush your truck thoroughly.
That’s because when air passes over the surface of the vehicle as it travels down the road, it creates an electrostatic bond and gives it a strength similar to a magnet. In order to rinse this film off, the bond must be broken. The fastest way to do this is by applying a 2-step chemical application process followed by a rinse. You would apply a low pH acidic detergent as your step 1, followed by an alkaline step 2 detergent to neutralize the "electrostatic bond" so that you can easily rinse away the road film.
By using both low pH and high pH chemical detergents, you’re more likely to remove both the positive and negative charges that create road film. In addition, using both makes sure to assist in the removal of all kinds of dirt and grime on the vehicle; the low pH targets oxidation and inorganic materials such as minerals while the high pH targets the organic, carbon-based materials such as grease and oil.
Each truck wash detergent has a purpose and when used correctly, is highly effective at cleaning your vehicles. If you use the wrong chemical, you could damage your truck or cause injuries. That’s why it’s important to know the chemicals in your detergents and how to best use them. Always consult the manufacturer of your truck wash detergents. To improve your truck wash process further, make sure you follow the five major cleaning factors.
