Diamond sharpening stones, consisting of a layer of diamond abrasives bonded to a metal plate, are known for their quick sharpening ability and durability. They’re favored by many sharpeners for their effectiveness with various steel types and their long-lasting reliability.
If you notice your diamond stones aren’t performing as efficiently as they used to, it’s time for some simple maintenance. While it’s easy to assume that worn-out diamonds are the cause of decreased performance, often it’s the accumulation of metal particles, called swarf, that’s the culprit.
Diamond stones are generally low-maintenance, but periodic cleaning can significantly enhance their performance. Here are three easy steps to revitalize your slow diamond stones and get them sharpening quickly again:
The Humble Eraser
An ordinary eraser can be surprisingly effective in removing swarf from between the diamonds. Simply rub the eraser over the stone’s surface to dislodge surface swarf. Afterward, brush away any eraser residue, and your stone will be ready for sharpening once more.
Soapy Water
Warm, soapy water provides a gentle yet effective cleaning solution for diamond stones. Apply a small amount of dish soap, use a nylon bristle brush (an old toothbrush works well), and create a lather on the stone’s surface. After a thorough rinse, ensure the stone is completely dry before storing it.
Mild Abrasive Cleaners
For a deeper clean, utilize a mild abrasive household cleaner like Ajax or Bar Keeper’s Friend. Apply a small amount to the wet stone and gently scrub the surface, preferably using a brass bristle brush. This helps to remove stubborn steel particles lodged between the diamonds. Rinse the stone thoroughly and ensure it’s fully dried before storing.
By following these simple steps, your diamond stones will be refreshed and ready for use, providing efficient sharpening for years to come.
