After searching, I clean my coins in a bath soap.
Take a plastic bowl in her cut chips with soap and poured hot water. Gently stir until medium consistency. and only tossed a coin.
Once a week I took out my coins and cleaned in warm water with old toothbrush.
Soap is only weakly alkaline, which helps to clean coins
