I am becoming a PC Consultant so I have been getting my stuff prepared for shows. My 2 stones have the vanilla coating on the sides. They are so brown b/c I could never get the outside clean. I wouldnt want to show them in that condition I think my Consultant at the time said I could use brillo but make sure I dont get the soap on the inside. I am trying to use a brillo pad now and I made sure to get most of the soap out of it. It seems to be helping. Is there an easier way to clean the outside of this stone? I have one more to go and its hard! Thanks!
