FAQ
Q: How to clean a granite inspection table?
Choose the right cleaner:
Avoid water-based solutions as Granite tends to absorb water. Acetone and alcohol-based cleaners will give the best results but cause a cooling effect on the plate.
Q: Can you use vinegar to clean granite counters?
Vinegar is made up of acids that can severely harm your granite. Even if it is diluted, vinegar may still leave acids on your granite countertops. This can cause your natural stone countertops to etch. You can tell that your granite countertops have begun to etch by seeing a small ring or some sign of a watermark.
Q: What should you not clean granite with?
Avoid Using Ammonia, Lemon, Orange, or Vinegar as Cleaners
Many homeowners turn to vinegar to clean up around the home. Before you spray on your granite countertops, keep in mind that these cleaners can damage the countertop's sealer. If you want to clean up your granite, make sure to use a soft cloth and warm water.
Q: Can granite get scratched easily?
Granite has a Mohs hardness rating of 7, meaning it is extremely durable and resistant to being scratched or damaged.
