We expected more pronounced surface etching on this sample compared to the others, as the Deox-C is very slightly acidic. What is surprising was the extremely even etching on the freshly cleaned surfaces. The higher concentration of Deox-C seemed to have zero pitting, in stark contrast to the other two samples. This is an indicator that some of the pitting had happened during the rust removal process, and the higher concentration rust remover had dissolved the larger chunks of rust before they could corrode the clean metal underneath. If you are working on large work pieces, this is also an indicator that you should have enough extra liquid to keep your parts submerged, just in case some of it happens to evaporate out of the top of the container. This is an indicator that you should immediately wash, prep, and seal your work pieces immediately after removing them from a Deox-C bath. However, the exposed band of metal near the untouched rusted portion had clearly flash rusted and is starting to corrode again. The pitting on the clean end of the bracket is less pronounced than with the Evapo-Rust solution, and the etching of the metal is very slightly less noticeable. The 5% Deox-C solution seems to have produced similar results to the Evapo-Rust, with some subtle differences. This band of exposed metal is clean and nearly rust-free on the Evapo-Rust sample. It seems that Evapo-rust has an additive that prevents flash-rusting: A convenient feature for when you aren't able to seal and paint your work pieces right away. Thanks to the effects of evaporation, all three samples have a band of de-rusted metal that ended up being exposed to the air for an extended period of time. There is some noticeable pitting as well as some mild etching in the cleaned area, but the brackets do not seem to be any thinner or more brittle than they were when we filmed our comparison. The work piece soaked in Evapo-Rust looks quite similar to when it had been in the rust remover bath for 24 hours. In order to preserve the condition of the work pieces, we only gently wiped the brackets down with a dry paper towel and before bringing them to the workbench for a closer visual analysis.

What this means is that this experiment is really a test of how whether these manufacturers did their homework in selecting their chelating agents, and how well they did in selecting the right chelating agents to do the job.īy the time we wrote this article, our three work pieces had been soaking in their rust remover baths for a full 30 days. Choose the wrong one, and it may end up disintegrating your work pieces instead of cleaning them. There are a wide variety of chelating agents out there, and the art is picking the correct one for the application. It's the same principle behind how a household water softener works, and is the same technique used by hospitals to treat patients with heavy metal poisoning. Chelation is a chemical process that involves using an agent which binds to a metallic agent and separates it from the surrounding materials, not unlike the way soap binds to grease and oils. The secret to achieving this non-destructive rust removal is a chemical process called chelation. This does raise the question - What makes products like Evapo-Rust and Deox-C so special that they can even make such a bold claim?

So let's test to see how true those claims are.

The value behind products like Deox-C and Evapo-Rust is that you can literally "set and forget" them. Leave your corroded parts in too long and they might end up eroding away some of the precious good metal underneath. The problem is that they need to be watched carefully. For example, muriatic acid and media tumblers can also do a very good job of removing corrosion from ferrous metals at a fraction of the price. After all, both of these solutions are more expensive than some very common rust removal products. While it might seem like a minor point, it is actually something worth testing. So we thought it would be a good opportunity to turn lemons into lemonade and use these neglected samples to test a claim touted by both manufacturers - That these rust converters won't damage clean metal. By the time we got around to cleaning up our workspace, our three rusty brackets had been soaking in their rust remover baths for an entire month. Then the whole excitement happened around current events, and we kind of forgot about the samples. About a month ago, we conducted a head-to-head comparison between two popular chemical rust removers, with some very surprising results.
