There are a variety of different chemical rust converters, but they'll make the rusty spots into a dark "primer" surface that's ready to be overcoated. If you want your spokes to stay shiny the only way I know of is some kind of polishing compound and a lot of work. Something like Simichrome polish, some rags, maybe a Dremel with felt cones, and elbow grease.

David,

I've had good luck polishing spokes with 0000 steel wool to remove the rust, that's 4 0's, and then preserving them with Strongarm. The Strongarm has to be re-applied occasionally, nothing short of re-plating or painting will preserve them long-term.

If the spokes are off the wheel, you can remove the rust with Evaporust, then preserve them with Strongarm.

Hey Kevin,

I saw a thread on Practical Machinist about Strongarm, they said it probably contained chlorine, so I was curious about your experience with it. You mentioned in this and your Powerplus thread about using Evapo-Rust and then Strongarm. Which Strongarm product are you using? Does either of these products contain hydrogen embrittling chemicals like Muriatic Acid or Chorine? Would this combination be good for a gas tank or other thin gauge steel?

Thanks,

Kevin

I like to use fine grade steel wool and SemiChrome. Great stuff. I was introduced to it in a fine Ducati/Moto Guzz/Benelli/Laverda shop years ago.

You would be amazed at the results - and it doesn't take a lot of scrubbing.

Kevin,

I don't know what is in Strongarm or Evaporust.

Evaporust only works on things that you can submerge in it, or it does work inside tanks as long as you jostle it around every once in a while, I have done this with good results. It won't work if you just spray it on the outside of something, it just evaporates and goes away. You can save it and re-use it, but eventually it becomes saturated with rust and quits working.

Strongarm isn't much good at removing rust, in my experience, but you can spray it on bare or rusty metal and it doesn't go away, rather it thickens up and leaves a film that seems to prevent further rust from developing.

Wish I knew more, but that's all I got. I'm just running on faith to some extent, but so far it's working.

I've also used Gibbs Oil to preserve rusty metal. Again, it has to be re-applied from time to time.

What material are the spokes made of?
Stainless: Avoid contact with rust particles and carbon steel particles. Polish with pure alumina.
Galvanized steel: Avoid contact with copper containing metals like bronze or brass. Scrub away loose rust particles with fine steel wool. Conserve with good corrosion protection oil, not WD40 junk.
Any: Avoid contact with chloride (sea water, de-icing salt), in case of contact wash asap with plenty of cold tab water.

Rust converters are not recommended since they usually contain phosphoric acid, which is useless to stainless and toxic to galvanizing layers.

Steel Wool

I just feel like I should reiterate, if you want to save as much of the original finish as possible, you'll want to use 0000 steel wool, which is known as Super-Fine or Finest. Fine steel wool (00) and Extra Fine steel wool (000) will probably dull the finish. If the finish is already gone, or you don't care about it, then it doesn't really matter.

Good luck with it!


Kevin

Thanks for the replies everyone.
The motorcycle is a 68 BMW R60. It is stock, some spokes are about half covered in a substantial amount of rust.

Where does one buy "Semichrome" and "Strongarm" and what are these products? Paste, liquid..?? Packaged in tubes? Thank you, dave

Strongarm is a liquid, I think you can only get it online at strongarmproducts.com. The owner, Frank I think, goes to all the vintage rallies but he doesn't bring any stock with him, he just pitches the product and tells you where to order it. Simichrome is a paste, you can probably get it on amazon.com or in some auto parts stores.

Simichrome is a paste in a tube. You might get it at a local parts store, but if you search online keep in mind that it's spelled "Simichrome".

Or, just wait until a tire change and replace the rusty ones. It sounds like not that many. New ones are available from the dealer and not that expensive.
