Best Rust Converter
Updated 13-02-2021 – Mia Cohen
With the ever-changing weather, it is but natural that valuable metals can rust over time. If you have any metallic items that have already caught rust, you need to be able to convert that rust and make the metallic element usable again. Oxidation can degenerate metals and make them weak over time. Rust can quickly deteriorate the object and cause it to breakdown and eventually become ineffective. Tools should be protected against rust, and in the case that rust does set it, they should be taken care of immediately. Leaving the rust on metallic items also decreases their shelf life rapidly.
Rust converters are used when there is already a build-up of rust on a metal product, and the rust has to be removed. Rust protectors are put early-on to save the metal from catching rust. Rust converters work on basic chemistry principles.
How do Rust Converters Work?
The principle behind rust converters is elementary. It uses a few basic chemistry components to protect the metal like steel. Since rust is excessive oxidation of the metal, it is necessary to first battle the oxidation, and then preserve the metal below from re-oxidizing.
The rust converter helps covert the rust into iron tannate using tannic acid present in the chemical composition. Tannic acid is usually used on ferrous objects to inhibit the corrosion levels and passivate them. Tannic acid helps in killing the rust and stopping the rust from spreading any further. It also prevents damage and does not allow it to multiply.
After the rust is stopped, the rust converter creates a protective layer or cover of 2-Butoxyethanol against future oxidation agents.

Buyers Guide for Rust Converter
Rust converters are only useful for metallic objects that are already covered in rust. Applying rust converters on items that do not have rust can adversely affect them and corrode a perfectly healthy metal. Before buying a rust converter, there are several things to consider.
Rust converters that are easy to use and store are always more popular than ones that are hard to use. Rust converters with sprays, brushes, rollers, and so on can be used conveniently and are also easy to store. If you are using a rust converter and applying it directly, please wear a pair of thick latex gloves to protect your hands.
Any rust converter you purchase should work on medium rust. Average usage is vital for getting out maximum rust from metals that have low ruse as well as those that have high rust. These products work best with heavy rust since it increases the productivity of the metal being cleaned. Before applying the rust converter, you should always brush a bit of the rust off with a wire brush. A single object may need 2 or 3 coverings to get the rust off entirely. Usage should always be checked before buying. You can use it on things like a chiminea or even tools such as edging shears or secateurs for better usability of them.
Most rust converters in the market require you to prep the metal before using the product. You may need to scrape or brush the excess rust off the metal with a wired or mesh scraper. This is done to remove excess rust from the whole build-up and allow the converter to do an efficient job. The rust converter should come in direct contact with the metal that has become oxidized. Leaving the rust on top makes the rust converter less effective and encourages a wastage of time.
Check the instructions on the rust converter before purchasing to either prep the material or leave it bare. Some converters do not require prepping, while some do.
Why is coverage crucial while buying rust converters?
Since rust converters function only on metals that have a build-up on rust on them, it is essential to check the consistency of the product. Coverage measures the efficiency of the rust converter to give you precisely what you require. Thick consistency in the rust converter is an indication that less primer is needed. Thick textures also provide the highest coverage on rusted products.
Why is performance important?
A rust converter that does not perform well is actually a waste of time and money spent on recovering your rusted products. Verify the effectiveness, sturdiness, and durability of the rust converter before buying it. Check performance reviews, pros, and cons, and features of the rust converters before purchasing them. Rust converters that still allow rust to reform even after application are not effective ones and should be discarded immediately.
