I think some commercial rust removers may be citric with a corrosion inhibitor added, this makes sure the citric takes off rust but does not attack the metal at all, but I've never felt the need to use such a product, but can see why they could be useful. If POR do use it, then I suspect they recommend the use of their highly expensive product to de-chloride it afterwards. Its compact size doesn't compromise performance, offering the power to tackle rust spots with precision and efficiency.

It penetrates deep into the pores of metal surfaces, dissolving rust and leaving behind a clean and corrosion-free surface. When I was sealing a lot of fuel tanks with POR15, their "acid etch" and "metal ready" products were very expensive so I bought commercially available hydrochloric and neutralizing solution, much much cheaper.

My experience of using hydrochloric acid you can neautralise the surface but it carries on rusting and everything nearby rusts. They mention that it removes rust, works well on larger, very rusty items, and is reusable for multiple rust-removal projects. So I am either going to need a large container and gallons of evapo-rust or use the recommend method of using paper towels covered in the rust remover.If you are used to acid type rust removers, switch now, this stuff is so user friendly, kind to skin etc but harsh on rust. Generally, I've never had a problem with the small extent to which citric will attack ferrous metal as distinct from dissolving rust. They are fairly heavy weight and watertight so you could have the part with enough liquid to slosh around a bit, and you could see how it was getting on. Normally rust removal is difficult and time consuming, but with Evapo-rust, you simply put the rusty component in the liquid and leave it a few hours.
