Blackening steel for decorative use
Q. I am using metal automotive brake tubing for the arms of a wood body chandelier. I wish to blacken these using Jax iron and steel blackener.
1. How should I clean the metal before applying the chemical? Does it need a solvent bath? Do I need to dip it in some form of acid to completely clean the metal?
2. How long should I immerse the metal in the Jax solution to achieve the desired effect?

A. The metal should be as clean as possible, Herman. If you are doing only a few pieces, you can scrub with pumice
⇦ on
eBay or
Amazon [affil links] and a household cleaner like Mr. Clean, and rinse well. Immediately go into an acid activator like diluted muriatic acid
⇦ on
eBay or
Amazon [affil links] , and rinse well, then try your Jax or whatever blackener according to the instructions.
You may find our FAQ on black oxide and cold blackening helpful. Good luck.

Q. I have a large piece of hot rolled steel I intend to use as a fireplace surround. After fabricating, there are greasy fingerprints and smudges along the edges / sides that I haven't been able to remove. we used lacquer thinner ⇦ on eBay or Amazon [affil links] Warning! flammable! , which cleaned it up nicely, except for the greasy smudges. I intend to put a clear-coat finish after I get it cleaned. Please advise.

A. Hi Anne.
Powdered pumice ⇦ on eBay or Amazon [affil links] in water, with a bit of detergent and a tampico scrub brush ⇦ on eBay or Amazon [affil links] is the safe and sure way. Good luck.
