I don't know or remember if this stuff has been discussed here before but I thought it might be interesting to those that wern't aware of it. I haven't tried it yet but I usually will try anything once.

I remember saying that when a woman asked me if I wanted to try something other than the regular stuff at 17 and since then I've never held back on new things to try.

We use Concrete Etch (Phosphoric Acid) - $10 a gallon from Lowes or Home Depot.

I thought concrete etch was Muriatic Acid. Anyhow, Phosphoric Acid, what ratio water to acid, and do you neutralize with water alone?

I use a SEM product called Rustmot. Great stuff and easy to use.

OSFO is what I've use in the past, it worked great.....

also used this: Rust Encapsulator

I've used metal ready and ospho in the past, those chemicals treat the rust, the stuff I refered to above removes the rust and if you keep it contained you can just keep running it over the surface till the rust is completely gone.

I got the distinction. Thanks for the info.
