Wearing your safety goggles and gloves, mix up a batch of rust accelerator adding ingredients in the order given:
- 16 oz Hydrogen Peroxide (use a fresh bottle)
- 2 oz White vinegar
- 1/2 Tbsp Salt
I assume you have placed your awaiting object in a safe place away from people, pets, and things you don't want to get rusted and by now you are dying to see some rust. Are you ready? OK. Let's go.
Spray some solution onto your object, soaking it from top to bottom all around. Now sit back and watch the magical transformation. It will start foaming and begin to rust before your eyes. Is that something or what? If it doesn't rust then you didn't degrease it enough or you didn't pickle it enough and will have to repeat one or both of those steps. Another possibility is the temperature is too cold. This works best at elevated temperatures. It is best to let the object sit in direct sunlight and heat up a little. Let it dry and repeat. I only had to let it dry for 5 minutes but YMMV (Your mileage may vary) depending on the ambient temperature. The rust patina should deepen each time you repeat the spraying and drying cycle up to a point beyond which there is no noticeable change. Keep spraying and drying until you are satisfied with the degree of rusting. I repeated the cycle about 6 or 7 times but again, YMMV. The pictures show the progression of the rusting process.
Congratulations! You have greatly accelerated a natural process and now have a piece of metal with an attractive aged-looking patina.
