You will get everyone's opinion IMO It depends on the coin & the soil cond,s it was in ,but I have tried many methods [never use lemon juice], I have never used the peroxide method either some coins clean up well by dry cleaning [ with a brush or toothpick] some clean up well with water & a med type brush ,lately Ive been rubbing [cents] between my fingers using baking soda and water. As usual DONT attempt to clean a key date or rare coin. I have also tried Mineral oil Olive oil ,each method has its merits, just depends on the coin tho, dry brushing does seen to leave a kinda shine on the cents ,that I sometimes like . So IMO just experiment and find the method that works the best for you. p.s. many times I have about scrubbed my fingers off to make a coin worth 5-25 cents look a little better. BUT to each his own. and how much time do you want to invest. 1st one needs to be lucky to find the coin and 2ed one needs to be lucky that time and ground action have been kind , as this apply's to any dug item. Best of luck.
