Can You Use Murphy’s Oil Soap on Quartz Countertops?

Quartz countertops are extremely popular in kitchens and bathrooms thanks to their durability, ease of maintenance, and stylish appearance.

Here is a detailed look at using Murphy’s Oil Soap on quartz.

What is Quartz?

Quartz countertops, sometimes called engineered stone, are made from ground quartz crystals combined with resins and pigments. The result is a very hard, non-porous material that resists scratches, stains, and heat.

Some key properties of quartz:

  • Extremely durable – quartz rates 7-8 on the Mohs hardness scale, almost as hard as diamonds.
  • Non-porous – food and liquids won’t penetrate the surface.
  • Resists stains – won’t absorb stains from coffee, wine, etc.
  • Heat-resistant – can withstand heat up to 212°F.
  • Variety of colors and patterns – from solid whites to metallics.
  • Low maintenance – simple cleaning and little sealing needed.

With proper care, quartz counters can stay looking like new for many years.
