I had aquired a very old and rusted crank mechanism for and old crank ice cream freezer.It was so corroded that it would not crank at all. I used this product on it several hours over a week. I got the mechanism freed up and I made ice cream in this freezer this weekend

Beware!
I used as directed. Didn't remove rust from porch concrete floor. But what it did do was leave white circles where the gel was, all over, ruining my entire concrete floor. I am in shock.

Let's see what we can figure out Bruce. Rust-Oleum Automotive Rust Dissolve Spray Gel is designed for use on iron, steel, aluminum, chrome, galvanized metal, porcelain, tile, fiberglass and glass, it is not suitable for use on concrete.

    I mean, WOW
    I rarely expect products from HD to actually perform... But THIS stuff is the bomb. The real deal. The cat's meow. I'd just spent $100 on a 1948 kitchen table - a great deal, no doubt. But the chrome legs were extremely rusty. I thought they were beyond repair. But NO! A little elbow grease, a wire brush, and wiping down with a brass bad did the trick. I am amazed. Pics below.

      I used it on the underside deck of a riding mower. It took about 5 applications to remove most of the rust. I wire brushed and scraped heavy deposits. I power washed to remove rust scale between each application. It didn't remove all of it. It did a decent job.

      I have a 10 in. table saw which has a steel table. I live in Florida where the relative humidity is high and promotes rust. Rust is the result of corroding steel after the iron (Fe) particles have been exposed to oxygen and moisture (e.g., humidity, vapor, immersion). I purchased the product several days ago and applied it to the table when I got home. The Rust-Oleum product contains Phosphoric acid which is a weak acid. The Rust-Oleum product did not meet my expectations. It did have some effect at removing the rust, but it was almost impossible to keep it from drying on the surface even though I kept washing the surface with water. In a search for a better rust remover, someone from a university suggested using HCL which is a much stronger acid and can be used to remove rust. It is important that a corrosion inhibitor is included, so that only the oxide is removed but the metal is never attacked. The recommendation is using HCl with hexamethylenetetramine previously dissolved in the acid.

      Works wonderfully. I had a wood stove that was rusted up pretty good from setting out in the weather for a couple years. It took the rust right off just as it said it would. The image shows what I started with. After I got the rust off I painted it with rustoleum high heat paint. It looks brand new now. I will buy this again.

      Seeing all these great reviews makes me question my experience but I read the instructions all the way through and then when I still wasn't getting results I google and youtube searched tutorials. Perhaps my rust job was just too big for this stuff, but at not point did the rust dissolve or wipe away. I tried the edges where the rust wasn't so bad and the rust didn't even 'sort of' go away. Pretty dissatisfied with the results at the moment and back to researching a better product for real rust removal.

      That is not what we like to hear! Our Rust-Oleum Rust Dissolver Gel uses a phosphoric acid blend to dissolve rust from metal surfaces. Severely rusted surfaces may require several applications or scrubbing with a wire brush for complete removal. - Rust-Oleum Product Support 2 Rustoleum

        Rust-Oleum Rust Dissolver Gel Spray is intended for use on rusted metal surfaces. If applying near a painted surface, you want to ensure that you are not allowing the product to dry on the painted surface.
