The best way to quickly and safely clean your jewelry at home is to pour half a cup of windex or a mix of ammonia and water in a coffe cup, and then put the coffee cup in the microwave and put on high until the solution is hot and bubbly. Remove the coffee cup from the microwave and then drop the jewelry in the cup and let sit for a few minutes. Remove the jewelry and brush vigorously with a stiff bristle toothbrush, especially on the underside of the diamonds. Finally, run the jewelry under some running water and dry with a paper towel. We are always more than happy to have you bring your jewelry in for us to clean, and have us check your prongs free of charge.
