Walnut shells have been used as a polishing media for years, and there are two main types on the market today. One type is treated to be antibacterial which helps prevent discoloration in metals that may occur during tumbling due to impurities being present within the media. The other type of walnut shell does not provide this treatment but it has better quality control than its counterpart with fewer broken pieces and more consistent shapes. Choose your preference based upon what you want out of your finished product or if you’re looking for an environmentally friendly way to polish metal items, try using some walnut shells! Try them yourself before buying any so that you can see how they work.
