Best Ways to Clean Coins Without Destroying Value?

Most of my coins are not cleaned with anything but water. vinegar is too harsh, peroxide has limited success. Would like to hear everyones tips for real results.
 
Most folks are a little gunshy about giving advice on coin cleaning. One mistake and the coin is ruined.

You didn't say what types of coins or their condition. Different coin metal alloys, as well as the different types of dirt or corrosion that is on the coin, may require different cleaning approaches.

I would do some searches on this forum and the Explorer forum for past posts on cleaning coins. There is some advice out there!

BE CAREFUL - experiment with coins that you would not care if they get damaged.
 
Olive oil for brass, etc. Sometimes you have to burn the green stuff off for a short while with lemon juice or white vinegar
 
If you know you have a valuable coin why not just let the buyer clean it? (that is of course if you plan to sell it)

I know that improper cleaning of a coin can destroy the value but can having it properly cleaned increase the value?

I don't know. It just seems prudent to have the value established first and worry about the cleaning second.
 
Each coin is a case by case basis and too many variables to just blindly say this or that. I clean coins daily as part of my job and the biggest challenge is to leave that final layer/toning/or surface composition alone. Some coins you just leave as they are though. All I can say is there is no substitute for seeing many many coins as a comparable and don't start out learning on better coins. Just a note...something as simple as soap and water can thrash coins where seemingly harsher chems. will do nothing. Knowing what and how is only gained with your powers of observation and seeing lots of coins both graded and not. Even if explicit directions are given, for some.......things will go sideways because of misinterpretation,lack of experience and impatience. Mostly leaving them alone is best for almost everyone.
 
my water deteriorates coins dramatically. I guess anything other than the conditions they were in will hurt them
