Q.I placed onyx tile on floor 3 months ago but recently finished the bath. the floors r now dul.how do I restore the luster

A.Hello Charles-Onyx is a very soft calcite stone.That being said improper care using the wrong cleaning compounds will dull the floor.Daily foot traffic will do the same.You will need the services of a stone refinisher to restore your stone back to its original luster.He or she will also explain how you can better care for your stone.
