Metal Finishing Compounds
Metal finishing compounds need to be used with a mop, felt etc. A loosefold mop is a popular choice for this final finishing process. The softest mops is a Reflex mop which is used in the jewellery industry for precious metals – sometimes this soft mop is not necessary on harder metals. But it’s down to the polishers preference. Yellow Bronco mops are becoming more popular but for most metals, you can’t go wrong with a general loosefold mop WDR which is a soft calico or a felt.

For Jewellers
We have a very comprehensive blog to help you choose compound for polishing jewellery.
FF9 and 309BX are very economical to use, they are large bars. They are very popular for finishing silver in particular.
Menzerna compounds are clean to use and produce an excellent finish on precious metals. P175 is particularly good for yellow metals i.e gold! Whereas M5 is better suited to white gold, silver, palladium etc. Use this compound with a very soft mop. With a pendant motor a cotton yarn mop is ideal, on a bench polisher a reflex mop is a good option.
