8 out of 10 lost all the whiteness to my slate clock but still left a bit of shadowing, instructions tell you to bees wax afterwards !!!! DONT beeswax will spoil any finish made with Marblack just a nice buff with a clean cloth after using marblack is sufficient, tried two types of beeswax both too me back nearly to square one, ( keep beeswax for your table tops not your slate clocks )
