"casting aspersions"

Aspersions? No, I'm relating my direct experience that the 5% DeOxit spray never worked very well for me at removing heavy oxidation.

It wasn't my intent to compare the two products based on chemical composition. I have no idea whether the MG product is going to work any better for me, and would never assume that would, based on an ingredients list. Perhaps it won't even be as good, but I'm willing to give it a try. I'm also not going to withhold my opinion (i.e. my aspersions) of DeOxit (at least the 5% spray) in the meantime.

I didn't have very impressive results with the DeOxit 5%, but wasn't attempting to condemn Caig's entire product line. Maybe their 100% product would have done what I wanted it to. I use their Pro-Gold 5% spray, for example, and I'm satisfied with its performance.

Above are two aging Dynaco AC plugs. The top one was cleaned with DeOxit 5% spray, the bottom one with metal polish. Both were cleaned with 90% alcohol afterwards to remove any cleaning residue, and to keep the comparison "apples to apples". Which one looks like it removed more oxidation to you?

The one done with metal polish as you would expect. But....the polish is probably a mild abrasive where the Deoxit and I admit is dilute, is a chemical cleaner. Maybe I'm wrong but I think what you are expecting the Deoxit to do is above and beyond it's call. I use it as a PM and occasional maintenance cleaner. If I had those plugs to clean at work I would have gone to the chemical cabinet and gotten a can of contact cleaner the electricians use to maintenance the breakers. That would do the job without elbow grease!

  I really should have said in my twin AC plug post that I wasn't expecting the DeoxIt to do as well as the metal polish. It would have been great if it had, but that's also unrealistic, given the mild abrasive in the polish, just as you noted.
  
  But the reason the experiment came about was because I cleaned the first plug with DeoxIt, and got very little tarnish showing up on my paper towel, even after several attempts. I figured there had to be a better way, so I found the old can of Brasso under my sink, a second Dynaco plug, and gave that a try.
  
  I sure can't squirt Brasso into a tube amp's bias pots though, so I figured I'd try the MG Super Contact Cleaner, since I used the last of my DeoxIt 5% just last night. If I think it does any better, I'll say so, but if not, I'll say that too.
  
  That breaker contact cleaner sounds like the ticket!
