How to Rust Metal Quickly

In this instructable, I show you how to rust method quickly using 2 techniques. The first technique uses chemicals and the second technique does not use chemicals.

There are several things which are difficult to fully explain with words and images, so be sure to check out the video tutorial below!

Metal objects to rust (Corrugated Metal)

Hydrogen peroxide

Muriatic acid

Plastic container for Pouring

Gloves

Safety goggles

Protective clothing

Respirator

Plastic Spray Bottle

Pump Sprayer

Baking Soda

Clear Lacquer

To achieve the perfect rust patina effect, choosing the right metal is crucial. Some metals are easier to rust than others, and the process may vary depending on the metal you’re working with.

The most commonly used and readily available for rusting is corrugated roofing.

I rusted corrugated roofing metal which will be used as the bottom skirt for an outdoor bar top at a fishing lodge.

First, remove any dirt, debris, rust, or paint from the metal surface using sandpaper or steel wool. 

By taking the time to clean, rough up, and prime the metal, you’ll be able to achieve a flawless and long-lasting rust effect.

First, pour the muriatic acid in a plastic container. Next, spray or brush the muriatic acid over the metal.

The muriatic acid cause a chemical reaction with the metal and may produce a little smoke. Don’t worry, this is normal.

Pour a new bottle of hydrogen peroxide in a plastic spray bottle.

Using a spray bottle or brush, apply the peroxide to the metal objects you want to rust. The more hydrogen peroxide you spray, the more rust will form.

Once the chemical processes start, pay attention to the different colors that form on the surface. Be sure to apply the solution evenly over the entire surface of the metal.

Allow the metal to sit for a roughly 10 minutes. The longer you let it sit, the more rust will form from the oxidation process.

Before rinsing, sprinkle baking soda over the metal to neutralize the muriatic acid. This prevents it from damaging the grass or anything else it comes in contact with.

Next, rinse the metal off with water.

The rust should be sealed with a clear coat protective coating to prevent further corrosion. Fortunately, there are various options for sealing rusted metal.

I used clear lacquer to seal the metal.

If you prefer to use no chemicals to rust metal, vinegar and salt work well and the process is very similar.

1. Mix equal parts white vinegar and table salt in a spray bottle.
2. Spray the solution onto the metal object, ensuring that the entire surface is covered.
3. Allow the metal to sit for several hours or overnight, depending on the desired level of rust.
4. Rinse the metal off with water and dry it thoroughly.
5. Seal the rust with a clear coat to prevent further corrosion.

Here are a few tips to help you achieve the desired effect when rusting metal with peroxide and acid:

• Use steel or iron objects. These metals rust more easily than other metals like aluminum or copper.
• Experiment with different ratios of peroxide and acid to achieve different levels of rust.
• Allow the metal to sit for longer periods of time to achieve a deeper level of rust.
• Create a pattern on the metal by using tape or stencils to cover certain areas before applying the rusting solution.
• Remember to seal the rust with a clear coat to prevent further corrosion.

Safety Precautions

When working with peroxide and acid, it is important to take the necessary safety precautions to avoid injury or damage to your skin.

Here are some safety tips to keep in mind:

• Always wear gloves and goggles for safety purposes when handling these chemicals.
• Work in a well-ventilated area to avoid inhaling fumes.
• Keep the peroxide and acid solution away from children and pets.
• Do not mix peroxide and acid in a metal container, as it can cause a dangerous chemical reaction.
