Product Review: Evaporust.

Restoration isn’t always about tracking down tricky to find parts or installing them, sometimes it’s a matter of just cleaning up what you already have and making it usable again. Knowing what tools and chemicals really work can make a tough job simple so I try to stay on the lookout for useful tools and products.
On a recent trip to Harbor Freight I stumbled across this and figured I’d try it out:


At around 10$ for a 32 Ounce container I figured it was no big loss if the results turned out to be disappointing. I tried it on a few things and I was pretty impressed so I thought I should share my results with you. I not only tried it on several different items but I tried using different soak times as well.

These bits were left to soak, undisturbed for 12 hours:



This rusty socket was soaked for about a day and a half, it was taken out about 3 times and rinsed off, I rubbed the extra rusty parts with my thumb just a little each time to expose the surface. The solution actually bonds with the iron in the rust and it slowly dissolves away from the surface of the metal, only removing the rust.


Note the color of the Evaporust before being used.



You can see I had good results with the socket, not too shabby!
The next sample was more of a long term test, these wheel caps were left to soak for about a month. I apologize for the poor quality of the “before” pics but suffice it to say they were pretty heavily caked with rust on the inside. I removed the caps from the Evaporust every couple of days (About 5-7 times in total) and gave them a quick light brushing inside with a plastic brush.




As you can see in the picture above the more you use the fluid, the darker it gets. Apparently it will reach a point of saturation and lose effectiveness, becoming jet-black in the process. However mine still works quite well despite looking like it’s all “used up”. Thankfully despite the color of the fluid there was no unwanted discoloration in the metal.


As it performs it’s chemical magic with the rust it seems to form a strange waxy looking substance (As you can see above) which rinses right off.
Now you can see why I felt the need to rinse and brush them from time to time.






As you can see, with the rust gone there’s a lot of pitting where it ate the metal. There’s still some thin surface rust in a few spots, but judging by the results thus far I’m certain further soaking will eliminate it completely. The bottle I bought was an ideal amount for cleaning up any smaller parts but for bigger jobs I found out it can be purchased in everything from single gallons ($30) to 55 Gallon drums.

When checking out the manufacturer’s website I found out that it is used by all 3 branches of the military and by many law enforcement agencies such as the CIA and FBI. Throw in the fact that it’s non hazardous and can be easily disposed of and I have to say I’m SOLD! I am definitely going to use it again in the future.
Check it out for yourself…you know you’ve got some weird little parts floating around that need a little TLC, give em a soak and clear off that rust!

Keep em rollin folks!

    Damn, this is cool. I really need to do this to some of my center caps and see how they turn out! Great article!

    Thanks! I was quite happy with the results, the outside of the caps just had a little surface rust which could have easily been brushed or sanded off but I like that I was able to just use the solution and remove it without any sort of abrasives being used. I should have included an after pic of the “shiny side” of the caps because they turned out looking great, the chrome really gleams now!

    Does it say what the ingredients are by any chance ?
    I wouldn’t see see how it could work without acid, but obviously it does seem to.
