cleaning the metal wheels on tenders

I have not heard of that product, where can you get it?  Might like to try it.  I've been using lacquer thinner and it removes the gunk nicely.  Clearly you want to keep the stuff off your hands and off the paint, but it does the job.

I have seen it in most ACE Hardware stores, it is in a black plastic container...

I never thought of Tarnx. I remember the old commercials where they simply dip a seriously tarnished fork into the liquid and how it shined like new money when they pull it back out. If anyone tries it, please let us know what the results are.

I have been using it for a while now, I put some in the cap and dip a Q-tip in it and swab away the dirt followed up by the wheel, One bottle will last a life time, keep away from plastic, suspect it would be harmful,  I have used it on old money and it works like a charm.  Always follow directions...

Looked up on the site and TarnX did not state that it works on brass, did state copper (brass is made up of copper/tin or zinc or both), so I would try it on a scrap piece of brass before I did the tender wheels.
I know some folks would frown on it but 4 zero steel wool (very very fine) works great as long as you have a air compressor to blow off any residue or a Scotch Brite pad # 7447 (which is a bite more aberasive).
If it is just gunk with no heavy tarnish I would use a solvent and be careful of any painted surfaces or plastics.

It might stain a shell, but black plastic wheels might be fine. Guess what the bottle is made of

May wipe the backside of a wheel?

I think I used the last of my Tarnex, but if I have any left I have some old AF wheelsets, so I might be able to test. If I do have some left I'll give results within 24hrs. Otherwise, your on your own to test )
