How to Open a Rusty Bolt

How frustrating it can be when a bolt has rusted and won't move. This article provides a really quick fix.


  1. Image titled Fizzy drink Step 1
    Obtain some fizzy drink. Any sort of soft drink/soda/beer should work fine.
  2. Image titled Pour Step 2 1
    Pour the fizzy drink over the bolt.
  3. Image titled Wipe Step 3 1
    Wipe it clean with kitchen towel.
  4. Image titled Unscrew Step 4
    Unscrew the bolt. The fizzy drink should have dissolved the rust build-up causing the bolt to stick. This doesn't de-rust the entire bolt but it does loosen the bolt so that you can unscrew it.

    Replace the rusty bolt. If your bolt is very rusted and old, it's time for a trip to the hardware store to buy a new one.


  • While WD-40 will probably do the job also, this method is more environmentally-friendly and kind to your health*. Besides which, you can quench your thirst with the remaining drink!
