I need some advice from anyone out there who has restored a Brass Soda Ash fire extinguisher. What is the best method for bringing a shine back to the brass?

Brasso and a whole lotta elbow grease.Never argue with an Idiot. They drag you down to their level, and then beat you with experience!

I have an antique "pump action" American LaFrance fire extinghuisher. I polished mine with Never Dull magic wadding polish and an old microfiber towel, then did a second polishing with Meguiar's Gold Class all metal restorer (available in the car care section of your local Auto Zone, O'Reilly's, etc.)"The education of a firefighter and the continued education of a firefighter is what makes "real" firefighters.

I'm surprised no one has mentioned ketchup, it works great, it has alot of acid in it. I don't know how it compares to the rest of the suggestions but it cleaned up VERY nice after using ketchup.

I have seen some that were acid dipped, but I wouldn't suggest that for any museum-quality stuff, especially where acid might get trapped behind rivited name plates, in seams, etc.
They did turn out nice, though.ullrichk

You can also use Grape Kool-Aid... I made a 5 gallon bucket up and let a old brass 2.5" playpipe nozzle soak in it over night and it came very clean... Then used little brass-o to get the real bad spot's...
By the way if read the back of a Kool-Aid package says not to store or use metal pitcher's... Make you think what's it's doing to your inside's....

Super-fine brass wool (not steel wool, as it will scratch the softer brass)dipped in a dilute solution of Phosphoric acid (Ospho is one brand name product) and just a little elbow grease. Thoroughly rinse with water and immediately dry with a soft cloth...Nothing better! The results will simply blow you away!
No matter what method you decide upon, the finish will be susceptible to oxidation (tarnishing) again if not treated very soon after cleaning. A good paste wax will work for a few months to year or so, but several thin spray coats of a quality, clear lacquer will last for many, many years to come.
I used this process on several old extinguishers that are in my den more than 8 years ago, not to mention having polished huge amounts of brass on my boat...Still looks like the day I finished it.

I also cleaned/polished one. Use the Brasso, Never Dull, and Wenol. None made the job easy. Lots of time and elbow grease. After I was done I thought, what about glass bedding it to get the tarnish off then polish with a buffer and polishing compound.IACOJ - Senior Jake
