Things to Consider Before Buying a Rust Converter

There are so many rust converters varieties in the market and as such, it’s easy to get mixed up when choosing the one that suits you best.

Just like most other products, some rust converter varieties will be better and more effective than others. I bet you’re looking for the most effective one, right?

Here a few things you should look for to ensure you buy a really good rust converter variety.


Rust converters are normally a moderately thin liquid. Therefore, you can apply them as a spray or with a brush.

Some expensive varieties are available in aerosol form, allowing you to apply a uniform coating. Such varieties allow you to save on the usage by minimizing wastage.

Different varieties will hold onto the metal object differently; this affects the application method. A thinner brand will spray easier, while a thicker one will stick better when applied with a brush.

If you’re looking to apply the converter on a long pore, it’s better to get one that you can spray rather than one that requires painting.

There’s something else you need to keep in mind – thinner converters will drip if you apply too much. Furthermore, they’ll need more coats especially if the metal is very corroded.

A thicker brand, on the other hand, adheres to the surface better and runs less risk of dripping. Also, it typically requires fewer coats.

Drying Time

You normally have to allow the rust converter around 20 to 48 hours. Nonetheless, this depends on the brands formula. Some brands will take less time while others will take more.

If you live in the warm climates, you will not have any problem letting the application dry.

However, if you live in a humid area, like the Pacific Northwest, you might have to wait for several days before the application dries. In this case, you ought to get a brand that particularly dries fast.


Depending on the brand’s active agent, the cleanup process can be instant or need lots of effort.

Most brands are manufactured from phosphoric acid bases that incorporate an assortment of other compounds to affect their properties.

Phosphoric acid bases are typically difficult to clean. However, some brands tailor their formula for easy cleanup with water and soap.


Many brands are made from phosphoric acids. You know what that means? They will burn you if they come into contact with your skin.

The good news is, the kinds of burn we’re talking about here are not associated with blisters or scarring. We’re talking about inflammation, irritation, and discomfort. To avoid such issues, I suggest using a pair of rubber gloves when doing the application.

I also recommend checking the brand’s degree of toxicity and going for the least toxic ones.


With regard to flammability, rust converters are certainly not equal. Some, like aerosols, are very flammable due to their compressed nature.

Some brands have incorporated additives in their products to reduce their flammability. Ensure that you check for an indication of inclusion of such additives in the brand you’re looking to buy.


Thicker rust converters tend to be more durable than thinner ones. Nevertheless, the brand’s constituents might determine its durability once the rust has been converted.

Pro tip: to boost the product’s durability, you can just paint, seal or treat the metal after applying the rust converter.

Note: some really good converters are able to protect the metal against future corrosion without having to do any additional treatment after application.

As you might have noted, the best rust converter for the job depends on the job you have it mind and on your preferences, and sometimes, on where you live.

Looking to apply it on your lawn mower, go for something you can spray. That will help reach all the parts of your machine.

Living it a high-humidity area, go for something that dries quickly.

Still not convinced that a rust converter is a handy, must-have item? Look at the following section, about the benefits of using a rust converter.

Benefits of Using Rust Converter

There are numerous advantages to using a high-grade rust converter. Here are some of them.

Saves money on repairs

If you have had to pay for repairs, then I suppose you know how costly that can be.

Think of your fence or even your metallic water pipes. How many times do you usually have to call those maintenance guys and how much do you have to part with every time? Let me guess – a lot, right?

Now, by using a good rust converter, you reduce the bending and wearing on such items. That means that you won’t need the repair guys as often as before, and thus you you’ll get to keep the cash you’d have spent.

Establishes a great base for future efficiency

Rust converters work to smooth out those corroded surfaces. In that regard, they avert further problems brought about by pits and clefts, which normally result from untreated corroded surfaces.

How to Use a Rust Converter

Ever used a rust removing chemical? Well, rust converters are quite different. They don’t remove the rust; they convert it into a black layer that stops the rusting process.

To apply the rust converter, all you have to do is follow these easy steps.

Step I: Prep the Surface

Some people don’t find this step necessary. However, by preparing the surface properly, you will help the product work more efficiently.

Use a tough brush to remove the excess rust. The goal here is to get off any flaking rust instead of sealing it.

Degrease and tidy up the surface with a piece of cloth, and then let it dry.

By doing this, you stop contaminants from interfering with the rust conversion process.

Step II: Apply the Product

Use a brush or roller to apply the rust converter. Applying it on big surfaces is more easily done using a roller. Remember, very thin rust converters need to be sprayed rather than painted.

The product will take around 20 minutes to dry but it can take a day or more to cure.

Apply a second coating to ensure great rust conversion.

Step III: Clean Up

The bottle should have some safety precautions; make sure that you read them. This particularly helps to protect you from the chemicals in the product.

Use water and soap to clean the product from the equipment you were using to apply the rust converter.

Here are a few tips and safety precautions that you should observe when applying the rust converter.

  • Apply it when the temperature is over 50 °F.
  • Don’t put used rust converter back into the bottle.
  • Use only oil-based paint for the top coating; don’t use latex paints.

Frequently Asked Questions (FAQs)

1.What do rust converters do?

Rust converters are chemical compounds that turn rust (known scientifically as iron oxide) into a stable black compound that prevents the metal from further rusting.

2.How long will the rust converter take to dry?

Around 30 minutes to an hour. It dries to smooth, black finish. To make sure that the treatment is complete, apply another coat. Note: it might take a day or more for the application to cure.

By doing good surface preparation, you boost the rust converter’s efficiency, and therefore you pave way for a high-quality result.

Before applying the converter, it’d be good to remove scale particles and excess rust with a tough bristled brush or sandpaper. The goal is to get off loose rust, as it destabilizes the surface.

Don’t remove all the rust; that’s not the object of this step. The rust converter needs to react with some rust and seal it.

Remember, rust converters don’t penetrate oils and grease. Hence, degrease the surface and tidy it a bit with a piece of cloth. This preparation step serves to prevent contaminants from interfering with the rust conversion process.

If the surface has been sprayed with salt water, rinse it with water and let it dry before applying the rust converter.

6.How should I apply the rust converter?

Rust converters usually come in liquid forms.

Now, look at the that liquid. Is it too thin? If that is so, then consider spraying it on the object.

However, if the liquid is thick, consider applying it with a brush or roller. If the surface you’re applying on is huge, a roller will make the work easier and deliver great results.

7.Can I apply it over a painted or non-rusted surface?

Yes. It will adhere to the surface but you should know that it won’t provide future prevention against rusting as effectively as it would when applied over a rusted surface.

Rust converters should not be thinned. They should be applied as they come in the bottle. But, shaking or stirring before application is okay.

9.How much surface will a gallon of the rust converter cover?

A gallon will cover up to 500 sqft of rusty metal. However, a porous, coarse or irregular surface will need more than that.

10.Should I paint over the rust converter?

It’s not really a requirement. But, in case the metal is outside, then it’s exposed to a higher degree of rusting elements. In that case, it’d be good to apply to apply 2 coats of high-grade oil-based paint over the rust converter.

By doing so, you’ll have extended the protective properties of the rust converter and it’ll be able to safeguard the object from adverse weather like rains, scorching sunlight, and salty mist.
