Introduction: Ink Removal From Soda Cans
Soda cans are involved in all kinds of "reuse" projects. If you have no idea just use the search bar on the instructable homepage desktop and type in "soda cans" and you received various results with projects where soda cans are reused.
However, if you need the can for some more decorative purpose the inprints on the outside wall of the can makes it useless. Therefore, this instructable demonstrates an easy method for ink removal on soda cans. As a result, you will end up with a can having a nice shiny outer surface as given on the picture. In this instructable a vase for flowers was built (see last step).
Step 1: Materials
Only few materials are needed for this project:
- Soda cans
- Nail polish remover
- Cotton pads
- Pressure cooker
- Hot plate
Please use various types of soda cans for your first project. Even so the procedure worked for almost all cans some did resist to the procedure.
Step 2: Method
Surfing through the internet you will find some procedure using sandpaper to remove the ink. However, with this procedure you will never end up with the polished shiny outer surface that you want for your decorative reuse project.
During the first attempts, various solvents were used e.g. nail polish remover or pure acetone directly. But as you can see in the attached video none of them did work.
Here is the trick: Put the cans in a pressure cooker for around 20 minutes.
Attention: ONLY ADD EMPTY CANS IN THE PRESSURE COOKER
Use the procedure that comes with your pressure cooker for sterilizing liquids. In my case I have to add a little bit of water to cover the bottom of the sterilizer. Then place all soda cans inside and close the lid. On the hot plate, I use maximum power to start (level 6 of 6). As soon as the pressure indicator reaches the second mark (2 of 2) power of the hot plate is reduced immediately to level 2 (level 2 of 6). Sterilize it for around 20 minutes.
After 20 minutes take away the pressure cooker from the hot plate and wait until the pressure is released. Then open the cooker carefully (hot vapor) and take out the cans.
Add some drops of nails polish remover to the cotton pad and start removing the ink.
Step 3: Make Your Reuse Project
As shown in the video the bottom part of the soda can was removed and the lid was opened using a tin-opener. A 300ml PET flask was found that fitted directly into the polished soda can. The PET flask was shortened to the correct length and then fixed into the soda can with hot glue.
I hope you like this creative reuse of a soda can which turned into a vase for flowers.
