First and foremost, cleanliness is vital. Granite measuring plates should be kept free from dust, debris, and contaminants that can affect measurement accuracy. Regularly cleaning the surface with a soft, lint-free cloth and a mild detergent solution will help maintain its integrity. Avoid using abrasive cleaners or materials that could scratch the surface.

Temperature and humidity control are also important factors in the maintenance of granite measuring plates. These plates are sensitive to environmental changes, which can lead to expansion or contraction, affecting their precision. It is advisable to store granite plates in a climate-controlled environment, ideally between 20 degree to 25 degree (68 degree F to 77 degree F) with a relative humidity of around 50%.
