Boiled linseed oil dries faster than cold-pressed linseed oil, and forms a much harder surface. You can prevent rust easily by coating the metal object with an oily shield using a cloth that has been treated or trunk with linseed oil. The longer metal components are exposed to humid air, the faster they will generally corrode. This happens because the moisture-saturated air reacts with oxygen and electrons on the surface of the metal. Metal corrodes at a much greater rate under humid conditions. Other substances, such as salt, can also increase the speed of the rusting process. For example, water speeds up the reaction. There are certain factors that can speed up the rusting process. No rusting takes place in absence of moisture.

Let the object air-dry in the sun for another five minutes or longer, depending on the size of the object.Ī single application of the solution should produce a subtle rusted patina on your metal object. The peroxide should begin to bubble on contact with the metal, and rust will start forming immediately. Once the salt has dissolved, spray the solution over the object to coat it partially or completely, depending on the desired effect. Vigorously swirl the bottle to mix the contents. Pour two cups of hydrogen peroxide, four tablespoons of white vinegar, and one-and-a-half teaspoons of table salt into a plastic spray bottle. STEP 5: Apply a solution of hydrogen peroxide, vinegar, and salt. As it dries, the acid of the vinegar will begin to corrode the surface of the metal and you will start to see rust appear. Let the object air-dry in the sun (five minutes or longer depending on the size of the object). STEP 4: Spray white vinegar onto the metal and wait several minutes.ĭonning gloves and goggles to protect yourself from splashes, pour white vinegar into a plastic spray bottle, then generously spray the metal. Place the sanded object in the center of a plastic bin that’s rested on either hard ground or a flat work surface in the garage.

STEP 3: Sand the metal with fine-grit sandpaper. Gently scuff off any remaining flecks of paint using a paint scraper. If your metal is painted, apply a paint stripper to the entire surface of the object according to the manufacturer’s instructions to remove this layer of color. Plus, hydrogen peroxide and vinegar can give off a moderate level of fumes, so you’ll want to work in a well-ventilated space anyway. Direct sunlight helps speed up the rusting process.
