Best Rust Converter – UK Buyer’s Guide

Rust is a compound that develops on a metal surface as a result of oxidation, and one of the main triggers of rust is water. When rust forms on metal surfaces, it tampers with its integrity and durability, and for this reason, people are often looking for ways to get rid of the rust from different types of metal. This is where rust converters come in.

Rust converters are a safe way to remove rust from a surface, leaving it as good as new. We’ve decided to take a look at the best rust converters in the UK in this guide.

How Do Rust Converters Work?

Rust converters use elementary principles of chemistry to eliminate rust from metal surfaces. In addition to removing rust, they also protect surfaces like steel.

After battling the oxidation process to remove the rust, the product then works to preserve the metal from further oxidising.

A rust converter also works by converting rust into a stable compound, which most of the time is iron tannate. This is made possible because of the presence of tannic acid in the chemical product. It helps to inhibit the levels of corrosion.

The rust converter acid also helps to kill the rust. By killing it, it also helps to prevent it from spreading further to surfaces that were not previously infected by rust. This helps to lengthen the lifespan of metal surfaces and products.

Hammerite 5092820 Kurust Rust Converter

The Hammerite rust converter is an incredible product for the British weather that is usually changing constantly. It is one of the most popular products of its kind in the market.

It quickly gets the surface rust-free and usable.

Using this product is quite easy. All you have to do is use a regular brush and concentrate on applying the product on surfaces that are covered with rust. However, it would help if you made sure that the product does not get on the rust-free surfaces. Once the product starts working, it will begin to turn bluish-black. If this doesn’t happen, then there is a problem.


  • It works perfectly on small rust-patches
  • It works fast
  • It is very effective

DINITROL RC900 Rust Converter & Primer 400ml AEROSOL

Unlike other products mentioned on this write-up, this rust converter is an aerosol solution. This means that you will not need a brush to apply it to the surface. You have to spray it to the infected rust surface. The aerosol rust converter can also be used on oxidized metallic surfaces. In addition to being a rust converter, the product also works as a rust inhibitor. This means that it can be used to prevent future formation of rust in the area that has been cleaned.

This rust converter works by forming a waxy layer on the surface. The layer dries up quite fast and can be repainted in no time. The rust converter can be used on car brakes, gates, metallic beadings, and other metallic surfaces in the house. Note that for the product to work well, you will need to apply two coats. This element, however, depends on the intensity and depth of the rust.


  • It works as a rust converter as well as a primer
  • It dries fast
  • It does not contain any chemicals like zinc, chromium, and lead


  • It is costly

Aquasteel Rust Converter & Primer

This is a two-in-one product that works as both a rust converter and a primer. It features a unique system for controlling corrosion, which was developed by Bayer-Wood Technologies. It is very effective when it comes to eliminating rust from metal surfaces. However, it is only designed for ferrous metals and nothing else. It can, therefore, be applied on boats and yachts as it has been tested for salt sprays. Other areas of application include gates, hinges, wheels of cars, and doorways, among others at home.

The product can be applied either using a spray gun or a soft brush. The method of application you choose depends on the specifications and the area of application. Before applying the product, you need to prepare the metal by either scraping or brushing it using a scraper. After doing so, you can proceed to apply it directly onto the surface of the metal. Once the primer is dry, you can continue to repaint the surface.


  • It works as both a primer and a rust converter
  • It can be applied using a brush or spray
  • It is very effective


  • It requires a lot of preparation before use
