I agree with all said, but with a few caveats. The first one is that muriatic acid is really very dangerous. Very dangerous. Leave a running hose nearby when using it. Long length rubber gloves, eye protection and also breathing apparatus. When the container is opened, the fumes alone will do permanent damage to your lungs and eyes so ensure there is a breeze from behind you. No
children within sight.
Make sure the drainage to be used is suitable. Not into local streams etc.
I would suggest that for more details, go to the
internet and gen up on the practices. The dilution ratios are important. When diluting, always add the acid to the
water rather than the water to the acid. (in some dilution processes, sufficient heat is generated to cause boiling - the last thing you want with HCl. If there is any splashing when the mix pouring is done then splashed water is better than splashed acid.)
Chrome can also be removed using fine grit blasting techniques.. Check it out on the
internet. Blasting will also remove any nickel. Muriatic acid may not.
No dangerous chemicals and a clean chemically passive surface with a uniform texture.
Many workshops have small blasters, and you won't be left with any remaining dangerous acid to store.
Chrome plating workshops also can put your stuff on heir cleaning/preparation lines.
