Also, when you are done pickling, you have to rinse with a lot of water to mitigate flash rusting because the steel will be in an activated state.
Keep in mind this acid can blind you almost instantly, it burns skin, and the fumes are toxic with a suffocating odor. In extreme cases, though, it might be best to dunk the steel in the concentrate right out of the bottle. In most situations, it is best to dilute this powerful acid with water. One of the fastest-acting pickles is muriatic acid. When abrasives and wire brushes are insufficient to remove extensive rust or heavy millscale, an acidic pickle can be most helpful. If the cold rolled is heavily rusted then it will more than likely need an acid pickle. Cold rolled steel just needs to usually be wire brushed followed by a wipe down with solvent. This is better than making gallons of corrosive acid solution for dipping. One way to accomplish this is to apply the pickle with a foam brush. One way to mitigate the hazards of handling acid is to use the smallest volume possible. This could be hazardous due to the fumes and exposure so be sure to wear gloves and eye protection. A good and inexpensive way to accomplish this is to use an acid pickle consisting of equal volumes of water and muriatic acid. To patina hot rolled, the mill scale must come off. Hot rolled steel has a black oxide coating called mill scale. Hot rolled steel is shaped and rolled at high temperatures. There are two major kinds of mild steel, cold rolled and hot rolled steel.
There is mechanical debris removal with abrasives and wire brushes, acid pickle, and solvent cleaning. To get the desired results any combination of the methods mentioned here may be needed. There are several ways to prepare the surface of steel. So, depending on what it is and how it’s used, you might want to seal it.If you are applying any finish to steel, whether it is a patina or otherwise, proper surface preparation is paramount. It only transfers when rubbed against something hard.

It doesn’t rub off on skin or flake off like bad rust. I haven’t sealed mine, but since it is actually rust, it can leave a little bit of rust residue marks when it is rubbed against something. You’ll also need a foam brush to apply the paints and possibly a water-based poly (this is my favorite), if you want to seal it after. Chalk Paint sticks to almost any type of surface, even glass and ceramics, so it’s a great primer on it’s own. If you aren’t painting metal, you can actually use chalk paint as the base under the iron paint. The rust could start to breakdown the metal without a primer. You don’t want that rust paint on bare metal. That primer is meant to PROTECT any metal that you want to use this on from the RUST. The Modern Masters Rust Finish Kit comes with the Iron Paint, Patina Spray, and a Primer. I wish Dixie Belle would put together a kit on their site too. This comes as a kit, so you don’t have to buy all the bits separately. The Second Option I tried is the Modern Masters Rust Finish Kit and it’s easy to buy on Amazon and your local hardware stores might have it in the paint department too. A look at the Iron Paint & Green Patina Spray I used from Dixie Belle.
