Canned air is also called compressed air and comes in an aerosol canister, much like hair spray. It is used to clean the tiny crevices in electronic equipment, specifically computers. However, you can also use canned air to freeze metal parts, such as bolts, to weaken the metal and allow you to break them. This technique is a good solution for bolts that have rusted or are otherwise stuck in place.
Things You'll Need
- Canned air
Attach the thin straw, supplied with the can, to the nozzle of the canned air by pushing it in until it is secure. If you do not have the thin straw, put on work gloves to prevent from freezing your fingers.
Turn the can upside down and hold the end of the straw 1 inch away from the base of the bolt.
Press down on the nozzle of the canned air and direct the cold spray at the bolt for approximately 30 to 60 seconds. You will see a thick, white frost form on the outside of the bolt.
Release the nozzle of the can and set it aside. Pick up a hammer and strike the bolt with firm force to break it off.
