80022 Water-Based Rust Converter Application Cleaner - 1 Qt

Rust was eating away at my truck’s rear quarter panels. Took a wire wheel on a power tool and ground out anything that was being eaten by rust. Cleaned with Corroseal cleaner and then applied the Rust Coverter. Quick, clean and very effective. Stopped the rust in its tracks. Waited a few days and sealed it with automotive spray paint.

great quality and great price !!!!

Works to kill rust but leaves an ugly brown rust looking stain on metal, it's hard to remove and hard to paint over so be careful applying only as much as needed and wipe excess away.

though a little pricey its a great cleaner

This product did not work at all ,even at full strength on metal ,ceramic, or concrete. It was as good as water! Do not buy !

I followed the instructions, and it transformed a rusty surface into a paintable clean metal window frame. Great find.

Works as described. The only issue was an odd powdery reaction with some brand-new steel I had welded into the floor of the car. It must have had a coating on it that I wasn’t aware of. Other replacement sections from a different source had no such reaction. Time will tell if this is a problem.

This is the cleaner recommended - and sold by - the most excellent Corroseal rust converter. For metal surface cleaning, mix it 1:8 with water and spray or brush on and let it sit. I have only used it in preparation for applying the rust converter so I can't comment on it's ability as a general cleaner. It did seem very effective at cleaning the rusty surfaces.I like that it is not solvent based, but water based - yet it seems to do a really good job. I plan to have some mixed in a spray bottle for other cleaning jobs.
