POR-15Rust Remover, Rust Dissolving Solution, Reusable and Biodegradable, 32 Fluid Ounces

I had 4 rusty wheels and soaked them overnight in the solution. Washed the wheels and the rust was pretty much gone. For heavily rusted items, i suggest using a wire brush or or a heavy grit sandpaper prior to soaking. Afterwards, I was able to sand and prep for priming and painting with normal effort. I'll use this product again.

It worked better at removing rust then I though possible! 5 stars

I love this stuff for soaking old rusty tools, to restore them. Great for restoring old Disston saw blades too. I've reused it a few times, but it doesn't get very many multiple uses before it's black and then coats your tools in a black coating too. It's hard to clean that off of smaller parts, but at least it still removes the rust at that stage. Weakens rapidly each time. Still, it really works great, especially on antiques, I just hoped to reuse it more than I did, for the $30 a gallon pricetag.

I was working on a project that included nearly 20 feet of chain and a separate pulley. I wanted something that would allow me to soak them rather than to spray. This fit the bill nicely.This is exceptionally easy to work with. After soaking the chain, everything rinsed quite clean. Water rinsing was an added benefit.It was interesting to find that there were areas of paint on the pieces that I hadn't noticed before due to the surrounding rust.

good

I've used this on a rusted bathtub drain protector, with its attaching screw. I soaked the rusty protector and screw in it for over 24 hours. The product does seem to have dissolved some of the rust, but not very much. I also tried it on a painted heating vent cover with small spots of rust from condensation. Too big to immerse. I applied the product and then re-applied it multiple times. Some rust comes off by wiping using a rag soaked with the product, but not much. The product is not what I hope for.

Had a little spot of rust on the threads of a gun barrel. I had tried a brass brush and a few other brushes to little effect. This made the rust disappear and removed the bluing. Now it’s an easy fix to eliminate any tiny bit of pitting and re-blue it.

The POR 15 is excellent but I saw no results in applying this to the metal I was prepping.
