Is it safe to use a sandblaster on my granite countertops?

It depends on the type of granite and how well you clean it. Sandblasting can be used safely if done correctly, but there are certain precautions you should take. Make sure that the area is properly ventilated, wear protective eyewear, and keep the nozzle at least 12 inches away from the surface. Additionally, make sure to use an appropriate abrasive material such as silica or aluminum oxide.
