To maintain design contrast after engraving on slate, it’s important to follow a few key cleaning steps. Begin by removing any dust or debris from the engraved area using a soft brush or a microfiber cloth. This will help ensure that no particles obstruct the contrast of your design.

Next, prepare a cleaning solution by mixing warm water with a small amount of mild dish soap. Dampen a clean cloth with the solution, making sure it’s not soaking wet, and gently wipe the engraved surface. Avoid using abrasive pads or harsh chemicals, as these can scratch the slate and diminish the clarity of the engraving.

After cleaning, rinse the area with clean water and dry it immediately with another soft cloth to prevent water stains. For extra protection and to enhance the contrast, you can apply a slate sealer. This helps to bring out the engravings while providing a protective barrier against dirt and moisture.

Finally, regularly dusting the slate and conducting occasional deep cleaning as needed will keep the contrast sharp and the design looking fresh.
