Keeping Hirano C and Comma chrome plated rolls nick and scratch free with Simichrome polish
Simichrome polish is well know in industrial circles for polishing tool and die molds, extrusion dies, precision metal products, and coating machine chrome plated rolls. It is also used as a purging compound to remove residue on mold and die cavities after prolonged molding of plastic parts. Simichrome polishes without scratching any ferrous or non-ferrous metal producing a smooth finish on even the most delicate, precision equipment and parts. Recently Dave Haines , the Manufacturing Manager for Yardney Technical Products, Inc., told us ” We use Simichrome polish on our chrome plated C and Comma rolls on our Hirano coating machine. Those rolls must be absolutely free from nicks and scratches and be smooth for good coating transfer to the substrates, and Simichrome gives us a great smooth finish on the rolls to do that. By the way, our coated materials are used in the electrodes that have made, among other things, the Lithium Ion battery cells that are presently running all over Mars on the Rover vehicles Spirit and Opportunity, and have been running for 4+ years longer than was thought possible for the mission.”

Simichrome polish used to shine the tombak buttons on an 1890s period Imperial German Infantry Tunic
Simichrome polish was used to polish the tombak (which is a copper alloy) buttons on the 1890s period Imperial German Infantry Tunic shown below. European uniforms from this era were very colorful. The buttons looked like pennies that had been buried in the ground. An application of Simichrome Polish restored them and helped to sparkle them like new. J. L. Danenberg, who owns this uniform, collects antique militaria – primarily Imperial German, 1840 – 1918. He tells us that many of the articles (uniforms, weapons, etc.) have brass, copper, or other metals that need cleaning. “Simichrome is the best product that I have found for this task. Being a thick paste, rather than a liquid, it stays where you put it. Nothing could be worse than getting polish where it DOESN’T belong – for example, the buttons on an Imperial Grenadier tunic (130 years old) are polished copper, often dull with age. Unfortunately, they are sewn onto heavy brocade bonded to wool. Spilling liquid polish would be a disaster, ruining a (very) valuable item.” If you are interested in Mr Danenberg’s collection, some of what is offered for sale by him, you can contact him here.

Keeping Fox Bassoon Keys Beautifully Polished with Top Brite Metal Polish
Recently a comment was made to an earlier post that was done on Top Brite Polish. It is always nice to read comments on how different polishes are used and the ultimate end user’s results. The comment read as follows:
“I am a bassoonist and my husband and I use to collect antique phones and ice boxes which all have sensitive metal parts that need polishing. We learned about Top Bright Metal Polish through another collector. We no longer collect phones and ice boxes, but I still play a very expensive Fox bassoon which has a great number of keys. The very fine texture of the Top Bright polish is perfect for keeping the instrument keys beautiful while not scratching or removing the metal surface from the keys. It is necessary to use q-tips in a number of small and hard to get to places and with little effort, the polish is easily applied and removed and brings the keys to a beautiful and like new shine.”
Top Bright Metal Polish is an American product made right here in the USA in the state of New Hampshire. If you can not find this polish at your local store, similar type polishes such as Autosol and Wenol are available online here.
