Does not resolve rust

I poured 1/2 gallon into my 60 gallon air compressor tank because I couldn’t drain the tank. The drain on the bottom of the tank is completely rusted across the rain hole on the inside of the tank. It was not feasible to disconnect the air compressor from the electrical and plumbing and then unbolt it from the floor to tip it over due to the weight of the compressor and manually unplug the drain so I spent the 40 bucks and had Home Depot order it for me. It has been in the tank for two weeks now and the drain is completely stopped up. This stuff does not dissolve rust as advertised. Now I have 1/2 gallon of liquid in the tank that can not be drained. The compressor is useless for painting now because of the 1/2 gallon of moisture in the tank. I’m on a fixed income and can not replace this 6.5 HP 60 gallon compressor for less than $1800 dollars. Bottom line. Do not waste your money on this rust dissolver.


It works!!

I soak my old parts on my 1971 Chevelle wagon and they come off with a lot of ease now. Parts are salvageable for use by other owners.


BBQ grate / grill

Can I use the WD rust remover on my bbq grate, which is showing signs of rust


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.
