The Corten Steel Weathering Process

Corten Steel, also known as weathering steel, transforms from its original state of a gray metal color to a beautiful orange-brown color. This process takes place over about three to 12 months, depending on how much the steel is exposed to the elements. While you may think of steel rusting as negative, the rust on the Corten Steel actually makes it more durable. This patina is stable, unlike layers of rust on standard steel. This patina acts as a barrier against water, humidity, oxygen, and pollutants.

1 icon


Place your planter where it can safely begin its transformation. You should be careful to place it away from pavement or stone, as these materials could experience rust stains from this process.

Next, you need to mix the ingredients that will begin the Corten Steel weathering process. Combine 32 oz. hydrogen peroxide, 4 oz. white vinegar, and 1 tsp. salt in a spray bottle.* Shake the mixture well.

Apply the mixture evenly across the surface of the entire planter. You’ll want to repeat this process several times a day. Maybe you concentrate more of the mixture in one area vs. another to get a unique semi-rusted patina on your planter.

*CAUTION: Handle the mixture with care, using safety gloves and glasses to avoid irritation, as this acidic mixture can irritate the skin and eyes.
