What is Corten Steel?

Corten is a trade name for a steel alloy material and is a weathering steel. The material is corrosion resistant steel and if left uncoated develops an outer layer patina. This patina protects the steel from additional corrosion. Corten Steel Planters are made to rust and will start showing the signs of rusting if you just put them outside for a couple months and let Mother Nature take its course!

How to make Corten Steel rust faster:

If you want to initiate the rusting quickly, first wash the planter with warm water and soap. This will remove any remnants of oil and the water will react with the metal initiating oxidation (rusting). Next, mix together the following ingredients into a spray bottle, or a fertilizer pump sprayer:

  • 16oz Hydrogen Peroxide (Use a fresh bottle)
  • 2 oz White Vinegar
  • 1/2 Tablespoon of salt

By using this mixture and lightly spraying the planter 3-4 times a day, you will achieve the fully rusted look in a matter of a few days!
