it took about 3 minuets to clean this 1942 silver nickel i found when i was out detecting.i would not recommend you clean a valuable coin this way.. i clean all coins i find because they are for me and not for sale.i just take a pencil with an eraser on it and rub if i where to do it for about 5 more minuets it would be even more clean and? shinny. find a dirty old silver coin and try it let me know what you think this also works great on Lincoln memorials i think that this nickel has had a few accidents
