Cleaning Brass Tools Without Chemicals Or Harsh Abrasives

wpid-wp-1442632799541.jpegAs a glass artist, I use a lot of brass tools because hot glass doesn’t stick to brass.  They tend to get tarnished (patinaed) when left sitting unused, which really isn’t a big deal, as this doesn’t generally affect the use of the tool, but it’s not very pretty.  Recently, I’ve come across a bunch of antique brass German fruit knives, which are AWESOME for moving hot glass! They’re over 100 years old, so some (most) of them have a lot of tarnish. I’ve been reselling them, so if you’ve purchased one, here’s how to get it all nice and shiny, like new, again.

These methods work on ALL brass, so if you have some old presses, doorknobs, buttons, etc., that need a good cleaning, here are a couple of inexpensive and environmentally friendly ways to do it.

Method #1

Ketchup (Catsup or however you want to spell it.)

Yep. That’s right! Good ol’ Heinz isn’t just for hotdogs & hamburgers. Just spread some wherever the tarnish is, let it sit for a while and then rub it off, rinse and dry. You may have to repeat a few times, depending on how bad the tarnish is.

Method #2

Lemon juice

Put your tool in a container and pour enough lemon juice in to cover the area to be cleaned. Let it sit for a while and then wipe off the tarnish. If needed, repeat. Once all tarnish has been removed, rinse and dry.

Once the tarnish has been removed, there might be a little discoloring (orangey or pinkish color). This can be removed by polishing with super fine steel wool (000 or 0000). This will give your item a nice shine and won’t scratch it as long as you don’t press too hard.

If you would like to purchase a knife, I have them listed here.

Tips:

1. Vinegar can also used, as well as citric acid dissolved in water.

2. If your item is really bad, you can add some salt to your lemon juice or vinegar to make the reaction stronger. Make sure the salt is completely dissolved in the lemon juice or vinegar BEFORE you put your item in the container.
