toothpaste has worked for me.  just make sure you get all of it off. (i.e. rinse well) and polish with a jewelry cloth.

You need a solution of gold sulfate or gold chloride to do it, but it has to be extremely pure, made with distilled/deionized water.  Remember to have your ring on the anion (the negative) and your gold source on the cation.

Get a can of stripeze....careful when using tho...highly flammable. follow instructions and do it outdoors. DONT bead or sand blast them! If you do you will never get the polished look back! Rinse them good. Get some simichrome polish or other type of polishing compound. Be ready to use some elbow grease...you might want to buy a buffing disk for your electric drill.

Soak, file, scrub, cream.  That's how I would do it.

As a coin collector, I highly recommend **against** cleaning a coin by any means other than a soft cloth.  If you clean a coin using any acid or solvent, you destroy protective coatings and etch away the metal of the coin, thereby reducing its value.\n\nAs a chemist and a coin collector, if you absolutely, positively MUST clean the coin for some reason, I suggest a very mild baking soda solution and a soft cloth, followed by careful rinsing in clear water.

Keep them clean, try not to play with them. Make sure the jewelry you have is genuine gold or surgical stainless steel. Soak it in sea salt water at night or when you can. Hint...Epsom salt, bactine and peroxide ARE NOT good. If things get worse, talk to a piercer and I'm sure they can help you out.\n\nAlso find jewelry that's comfortable in them. CBRs/rings might be easier to use than post earrings(bad idea) or barbells(curved or straight)

sounds like an allergy to me.  take off all jewellery for a few days and see if it goes away.  I can only wear jewellery that is pure gold or i break out in a rash too. good excuse to get some nice bits of gold though.

Use a mild hand or dish soap. Just make sure you rinse them very well, to get rid of any soar residue. Also it is better to let them drip dry, if you use a towel you will end up with fuzzes all over them.

best thing for ringworm is "denerex". It is a dandruff shampoo. I had really bad ringworm and it got rid of it when nothing else could.

Where do you live? also... What type of cleaning?\n\nFlyers are useless.. and you are going to really struggle if you are not specific enough.

see what you can do with canned air. \nIf you can't get everything off with air, rinsing with alcohol will be much better than rinsing with water as it will not cause rust and evaporate very quickly, leaving no moisture behind. Soap and water isn't good for any electronics.

Don't clean them, this will void them of any value. Believe it or not, old, dirty coins are worth a lot of money!\n\nAlso don't handle them a lot, the oils from your hands will get them more, for lack of a better word, "corroded". Put them in acid free protectors.
