Reaction in Glass container vs Plastic matters.

I saw almost no effectiveness in a glass container I used. Excelent response in plastic now the manufacturer says nothing about this that I'm aware. Not sure why but it does not work in a glass container well at all so use plastic.



This product works well. I used to to remove some rust of a couple of my tools and it worked amazing. It came off and they look brand new. The smell didn’t bother me. I would definitely recommend this product for rust removal.



I am impressed with this rust remover soak. It seemed to work pretty quickly and did not cause issues with anything I used it on. Normally I just throw away rusty items but am glad that I will not have to any longer.


Cleans up great

The WD-40 Specialist Rust Remover Soak, 1 Gallon is a great product to get rid of in wanted rust. Easy to use and works in minutes. Best feature of it is that there’s no lingering after smell like some other products. Would definitely recommend!


Great product

I had some tools that got left out in the rain. I got this to get the rust off of those tools. Both had moving parts seized up. After a 12hr soak they freed up and are working again like new. I have more rusted items I am going to use this product on.


Works as advertised

I got this a few weeks back to help me remove years worth of rust on some small hand tools I inherited. I was skeptical at first because these tool were neglected for decades. To my surprise not only did it remove all rust after soaking but also lubricated the moving part nicely.


Works as intended! Removes rust well!

I used this for some jewelry that I had left outside for too long. It's super easy to use. You just clean the dirt and grit off the jewelry before then soak it entirely for about 30-60 minutes. It's also nontoxic, so you don't have to worry about using gloves, although, I'd still recommend it. After the soak, wash it off with water, but you may need a tad bit of scrubbing.


Works Well !

I decided to try this using some old tools from the last decade and let them soak overnight to completely take out the rust. I was actually surprised witht he results and was pleased. The wooden portion of the tools were not damaged during the process as well.


Great rest remover

This product is a great rust remover. It removed a lot of rust from my old tools I just had to soak them overnight I would recommend this product to anybody I know who has tools I've recommended to my dad and to my son it is a great product

Around the house

This is great to keep around the house or in the basement, never know when your going to need it.i didn't use the whole bottle just soaked a few tools I had left outside and they rusted. I put in a shallow bucket and let the soak do its magic.
