Needless to say, we field quite a few questions about how to get the best results with our products. That’s why in today’s post, we’d like to cover a few of our most frequently asked questions about black oxide chemicals, operating instructions, and more. Of course, you should also know that we’re available to answer any additional questions you may have, so feel free to contact us at any time.

“What’s the best way to maintain proper boiling temperature while black oxiding?”

Our best advice is to keep your tank at 285ºF by checking the temperature regularly and adding salts to raise the temperature if need be. To lower the temperature, simply add a small amount of cold water.

“How long do my parts need to stay in a black oxide tank?”

It depends on your exact situation, but generally speaking, 15 minutes to half an hour is the ideal time to get great color and resistance to corrosion.

“How long does the average black oxide bath last?”

It depends on a number of different factors, but the average time for a black oxide bath to last is between 1 year and 5 years. Restore the salts in your bath by adding fresh salts on a daily basis for the best results.

“Is it okay to leave a handheld thermometer in the black oxide tank to check the temp?”

Our advice is to check the temperature, then remove your thermometer. Rinse the stem off with cold water for the best results.

“What should I wear to protect myself while working?”

We recommend always wearing long sleeves and coveralls when you’re using a black oxide tank. You should also make eye protection and plating gloves a part of your routine. If you get black oxide solution on your skin, rinse it immediately with clean water (cold water is best), pour on white vinegar, and then rinse it off again.
