How to age new hardware?

[m22mike]

Like John said....be careful with muriatic acid...nasty stuff full strength for sure.
I have used it ( outside, it gasses real good ) to remove heavy rust from parts like rotors and drums. Then after rinsing with water and neutralizing with baking soda the stuff still develops a coat of rust, at which point I clean with phosphoric acid or media blast.
If you are just trying to destroy some of the new finish on zinc and phosphate bolts I would just experiment with some short dwell times to see what happens ??

A note here that Mike mentioned. Make sure you use it outside. If you have it open inside it will start gassing and will rust any and every bare steel part in your shop or garage. I use it in a loosely covered container outside and when I am finished I put it all back in the sealed jugs when I bring it back inside.
