    From what I understand, There may be a slight communication/product barrier. I have read elsewhere that when Europeans refer to "vaseline", they are actually refering to Mineral Oil.

    I bought a 79 cent bottle of Mineral Oil at my local Target store (in the health & beauty aisle) and applied it to some really corroded tinnies I have. As mentioned, It doesn't "put back" lost metal, but it did remove the zinc pest and made the tinnies look 1000% better. I just dumped them into an empty butter tub filled with the MO for a few hours.

    European members: Feel free to correct me if I am mistaken about the vaseline reference. It's something I read elsewhere.

      I believe the American term for Vaseline is Petroleum Jelly.

        I leave a very thin coat on vaseline on mine (which after wiped off and about a week of time) leaves the badge looking like vaseline was never applied, except for the zinc pest is gone. Just my personal preference. I believe this thread is of great importance as the loss of these badges is in my mind a loss of investment and a piece of history.

          I read on another forum a few years ago about mineral oil. I use petroleum jelly myself as I allready had it. I put it on and gently wipe it off. You want to keep a thin layer as it acts as a barrier and will prevent air from contacting the zinc. I know people who have been doing this for over 10 years with no ill effects.
          Another way to protect tinnies would be to clearcoat them. Someone I know did this about 30 years ago, and except for a slight yellow tinge, they look like they did 30 years ago!

              Zinc Pest et all

              Over my fifty years of collecting, I have found the following concerning this problem.
              1. Zinc Pest is a result of air contaminates and moisture. KEEP HUMIDITY below 40% (if possible) and don't store items in paper or cardboard as they tend to hold moisture and have acids in the material that promote zinc pest. Plastic sleeve are just as bad as coin collectors learned long ago that the chemicals in the plastic tend to discolor and tone.
              2. All zinc and bronze medals respond well to virgin olive oil better than vasoline. Vasoline is sticky and tends to draw dust that contains contaminates that will promote discoloration and darkening. Olive oil (when used moderately) will not do this.
              3. Wash medals in soap and water (ivory bar is best) and DRY WITH HAIR DRYER TO REMOVE ALL MOISTURE PRIOR TO APPLYING OLIVE OIL. When moisture is still present and olive oil or vasoline is applied it will be trapped under the surface and cause damage.
              4. Store medals where the air can exchange, but not uncovered to allow dust to settle on the surface. A glass case is best, but you must wipe them every year, or more often if the dust tends to accumulate faster.
              5. DON'T APPLY VASOLINE OR OLIVE OIL TO PAINTED OR PLATED ITEMS as it will work under the paint or plating and cause the surface to bubble. This is seen in the numbered badges by jfs and gb. These badges are a real problem as the base metal is zinc and, once the surface plating shows some minute cracking and bubbling, can develop zinc pest and other types of destruction.
              I have no good solution to this problem with these badges.
              Gold washed badges and bars don't seem to be affected by the olive oil, but the gold on these will darken over time when exposed to sunlight and fade.
