These polishing cloths are for polishing and brunking platinum, gold, silver, brass, copper and other metals.
The pads are very pleasant to "highlight" your jewelry quickly after the use of liver of sulfur (blacks), quick touch-ups also make them very easy when removing oxides on old jewelry even without the use of polishing paste. The wipes are waterproof so polish with some water if necessary and remove so stubborn oxides of metals. The 5cm large squares are made of tightly bound cellular foam with permanently bonded micro-abrasives.
Note: Do not use for gold plated jewelry.
