Things To Consider When Selecting The Best Rust Converter

A lot of factors can influence your search for the best rust converter. Let us look at some of the critical considerations to be mindful of while making a purchase.

Strength

Every product comes with a different formula. Consequently, their power also differs. Some converters are meant to deal with more minor rust spots that have only just surfaced. Harder solutions focus on tackling rust that has gathered on the surface over the years.

The best rust converter is one formulated for “medium” level rust. The kind of rust that has been there for a while but hasn’t caused any serious harm. The chemical strength of these converters makes them ideal for almost all situations.

Formula Base

Rust converters can either be water-based or chemical-based. Different formulation is ideal for different cases. While water-based converters are non-corrosive and non-toxic, they are a little weaker.

Chemical-based rust converters can be rather harsh. However, they are better suited to deal with old and stubborn rust.

Flammability

Flammability is an essential consideration regarding both the application and the storage of the rust converter. You should not store flammable cans of liquid converters in a warm space. They may not cause severe burns, but they can lead to irritation and inflammation in the skin.

For application on vehicle parts that you need to weld, it is always better to use non-flammable rust converters. You should ensure that the converter is always at the appropriate temperature. You should also always wear gloves while working with rust converters.

Application Method

Rust converters are available in spray cans and as liquid or gel. Spray bottles, or aerosol spray can, can make the job quite simple. However, they create a mess. The formula in sprays is also less dense at times and may need multiple applications to work effectively.

In contrast, gel or liquid solutions come with a thicker formula and do not create a mess. They get painted on the rusted surface. They are better suited for spot-specific applications.  

Toxicity

Since rust results from a chemical reaction, converters also create another chemical reaction to treat it. All converters come with compounds such as phosphoric acid, which can potentially be volatile. 

You should be aware of the toxicity of the product you are using to decide if it is safe to touch and how you should clean it up. Toxic chemicals coils lead to stains, irritation, or even shedding of the skin.

Drying Time

While drying time is not a crucial consideration, it is helpful when you are in a hurry. A lot of rust converters take a couple of days to dry out. However, some products get rid of the corrosion within a few hours. You can pick a quicker option if you do not like waiting long before painting or sanding over the corroded area.

Future Protection

The entire process of converting rust and then painting or sanding it is long enough as it is. Going through it, again and again, can be a tiring cycle. Many rust converters add a protective layer to the surface to avoid any further corrosion.

This feature may not be necessary if you prime or paint the surface. All metals are different, and you need to figure out what course of action is best suited for your metal products.

FAQs

Let us examine some of the commonly asked questions for better clarity.

Does Vinegar Clean Rust?

While rust converters are a better option, you can turn to DIY remedies if you are in a hurry or run out of a converter. White vinegar is an effective ingredient to get rid of rust. The rust reacts with the vinegar and dissolves in some time. There are many different ways of using vinegar to clean rust.

If you are cleaning a small object, you can simply soak it in vinegar for a couple of hours. After that, wipe it, and the rust should be gone. Alternatively, if the object is large, you can pour the vinegar over its surface and let it settle. 

Another effective method is to soak a cloth in vinegar and then wipe the surface clean. You could also dip some aluminum foil in vinegar and clean the rusted surface with it. 

Regular vinegar is weaker than white vinegar when it comes to dealing with corrosion. If you wish to use regular vinegar, you will have to soak the object in it for 24 hours and then scrub off the rust.

How Do You Protect Bare Metal From Rust?

Once your rust remover has done its job, you should ensure that your metal is protected from any further corrosion. Here are a few simple ways in which you can prevent further rusting.

  1. Apply a coat of oil to prevent moisture from reaching the surface and oxidizing it. 
  2. Use good quality paint on the metal to protect it from corrosion.
  3. Prevent scratches or cracks on the surface as they can hold water in them.
  4. Store metal products in an area with low humidity and moisture.
  5. Scrape off the rust as soon as it appears. Afterward, scrub the surface with warm water and soap and apply a coat of metal conditioner.

What Is The Difference Between Rust Converter And Rust Remover?

So far, we have read a lot about rust convertors. Now, let us look at rust removers. These removers strip the rust off the surface with the help of a concentrated chemical solution. They are pretty different from rust convertors. 

Rust removers are mostly hazardous and corrosive. The acid eats away all the rust from the surface of the metal. Converters, on the other hand, are usually non-toxic. They convert the rust into non-corrosive compounds that you can paint or sand off.

The process of using rust removers is pretty complex. You will first have to soak the item in the solution. You will have to coat the surface with the rust remover for larger objects and then cover it with plastic. You may have to do this process multiple times to see results.

In contrast, rust converters are much less complicated and give quicker results. Some converters even work as primers and prevent future rusting.

It is better to use a rust converter if you plan on painting the surface eventually. In fact, converters that are also primers will make your job much easier. However, if you want to resurface the object and want the result to be exposed without any paint or primer, rust removers will be better suited.

Closing Thoughts

A rust converter is a worthwhile investment if you want to keep your metal products, such as vehicles, in good shape. You should examine many significant factors such as strength and flammability before investing in a converter.

While picking out the best rust converter is not an easy task, we hope this guide helps you make an informed choice. Now that you are know all the relevant information get rid of that rust!
