We’re specifically addressing rust here. Say you’ve had a barbell outside for a while and it starts to rust–don’t throw it out! That would be wasteful and also hurt the bank! That’s why we want to show you how to clean a barbell, so you don’t feel like you have to toss it if it’s not looking the way you want it to. Not all barbells are created equal, so cleaning the inside after taking it apart can be a little different based on what you’re using. If you do, however, find your barbell starting to rust, here’s an easy and CHEAP way to take that rust off and make it look new again.
