How to Rust Tin Cans
If you're trying to rust tin cans, or change the surface to iron oxide, you're probably working on a craft project. Rusting metal gives any project an old, country look that's appealing. The elements can rust metal naturally. The problem is that it takes a long time to wait on nature to corrode metal.
Things You Will Need
- Table salt
- Spray bottle
Give nature a helping hand and rust tin cans on your own.
-
Pour 4 tablespoons of table salt into a spray bottle. Add 2 pints of warm water and shake it to dissolve the salt. This will make a fairly strong salt water solution.
-
Collect the tin cans and the salt water solution outside. Choose a location that's away from plants and grass. Spray the cans liberally with the salt water, then set them out in the sun.
-
Spray the tin cans with the salt solution every day until they get as rusty as you desire.
Tip
If the tin cans are painted, you can accelerate the process of rusting by sanding them first.
Warning
Salt water will kill grass and plants, so stay away from these when you spray the tin cans.
