These toxins are more likely to react with your skin or clothes as it would react to rust.

Removing rust from the frames need not be a painful ordeal anymore– especially when you have a list of the best rust converter for truck frames.

While most truck owners would prefer the services of a mechanic, you should know that this is a simple process that you can do on your own without any third-party assistance.

However, there is a catch to this– you need to acquire the necessary skills and knowledge.

Also, keeping your truck frame protected will ensure that it serves you for a long time before you can think of making replacements or major repairs.

Since we want you to have the most memorable experience as a truck owner, we have compiled invaluable information about rust converters for your consideration.

So, let’s get started!

Types of Rust Converters

Before we go on, it’s important to first understand what a rust converter is. Simply put, a rust converter is a chemical solution that when you apply on your truck’s frame, removes the rust corrosion layer on it.

Rust is a combination of iron and oxygen to form an iron oxide in a chemical reaction. When you apply a rust converter on this surface, a black-blue solution is formed.

This is the product that comes out when a solution of a rust converter comes into contact with an iron oxide– rust.

Moreover, different types of rust converters are available in the market. Therefore, you must know what they are made of before deciding what is best for you.

Furthermore, the manufacturing material is dependent on the kind of rust and the purpose of the converter.

So, with this basic information, here are the types of rust converters– depending on the material of manufacture– that you will come into contact with.

1. Tannin Based

A significant number of rust converters are mainly water-based and contain tannic acid as an ingredient.

When you apply tannin based rust converter to a rusted metal surface, the chemical compound in it reacts with the iron oxide to form a bluish solution.

Besides getting rid of the rust, the black solution forms a protective layer on the metal surface.

One key benefit of this is that it reduces the frequency of removing the rust on your truck frames. This, in turn, saves you time and money. Isn’t that amazing?

2. Phosphoric Acid Based

Phosphoric acid plays three major roles in rust eradication. These are; rust removal, rust conversion, and rust inhibition.

To enjoy the optimum benefit of using phosphoric acid-based converters, you should apply them in sufficient amounts.

Moreover, phosphoric acid-based converters are effective as they form a layer of water-insoluble material on your truck surface.

This layer– iron sulfate– helps to prevent any future corrosion, thereby, keeping your truck frame safe for a longer period.

3. Lignin Based

Lignin-based converters are probably the least infamous and least used. However, they fight rust like the above-mentioned rust converters.

A solution of lignin-based conversion contains chemical compounds of aromatic alcohol.

Moreover, it is the presence of hydroxyl– a reactive agent– in lignin that makes it an effective rust converter.

Therefore, it can modify the chemical composition of iron oxides– rust– leaving your truck frames rust-free.

4. Combination of Tannin and Phosphoric Acid

Best Rust Converter For Truck Frame, This combination comprises the best rust removal properties of tannic acid and phosphoric acid. When this compound reacts with rust, two compounds are formed. These are; iron tonnes and iron phosphates.

Besides, the resultant compounds are water-resistant and prevent future corrosion and the formation of rust.

The combined efforts of two rust removal agents make this type of rust converter super effective.

How to Remove Rust From Your Truck Frame

By now, you already know the various types of rust converters. Moreover, you are aware of the factors you should consider when buying a rust converter. However, there is one final requirement that’s super necessary.

How do you remove the rust after availing of all the necessities? Here is a procedural guide for you.

1: Wear protective gear such as a pair of gloves and glasses.

 2: Using the right tape, create masking around the affected area.

 3: Depending on the type of rust converter, begin to spray or brush the affected area.

 4: After a few minutes of letting the surface dry off, wipe any remaining residue with a rag.

 5: If there are still some patches of rust on the surface, you can use sandpaper to clear it.

 6: Using grease and soap for wax removal, clean the surface, then let it dry.

 7: Spray some clear paint on the surface up to three times and let it dry for 2-3 days.

Voila! There you go. If you follow these steps keenly, you will effectively remove rust on your truck frame.

Can You Pressure Wash Rust Off Metal?

Using a pressure washer, you can effectively remove paint from wood surfaces, metal surfaces, and concrete surfaces.

Moreover, for rust removal, you need to consider using hot water under significant pressure.

This will remove the rust faster than you can imagine.

Final Thoughts

The presence of rust on your truck frame should not freak you any anymore.

In this guide, you have acquired the essential information that you can use anytime and anywhere for effective rust removal.

Also, the four types of rust converters are; tannin-based rust converters, phosphoric acid-based rust converters, lignin-based rust converters, and a combination of tannin and phosphoric rust converters.

As you shop for a rust converter, ensure you go for what fits your exact needs.

You can consider ease of use, toxicity, longevity in protection, flammability, and ease of clean-up after use.
