  1. I have read that using water and baking soda to remove dirt/ grime from coins is the "proper" way to clean coins. I have been collecting for a while as a hobby. Now I am older, have completed some sets, and want to send in for grading and slabbing. Did I screw up decades of hunting by cleaning with water and baking soda? I am now afraid of getting back the dreaded "cleaned" designation.
