Is it okay to use S O or Brillo pads on porcelain sinks?

No, it is not okay to use steel wool (S O) or Brillo pads on porcelain sinks. These materials are too abrasive and can scratch the surface of the sink. Porcelain is a hard, non-porous material that is made from clay and minerals. It is fired at a high temperature, which makes it durable and resistant to wear and tear. Steel wool and Brillo pads are made from metal, which is harder than porcelain. When these materials are used on porcelain surfaces, they can create tiny scratches that can weaken the material over time. These scratches can also make the sink more susceptible to staining and discoloration. Instead of using steel wool or Brillo pads, it is recommended to use a soft cloth or a non-abrasive cleaning sponge to clean porcelain sinks. These materials will not damage the surface of the sink and will still be effective at removing dirt and grime.
