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

I restore old trucks with parts that are obsolete (can't get them anymore) and fight corrosion daily. This works great soaked overnight aggitating the solution and parts periodically. Let soak overnight and the rust is dissolved

Thanks

Decent but comes in a small bottle

good

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.

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.

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.

Product is not worth it. It does not work. And try calling their customer service department. That too does not work. Save your money.
