Deep scratches in travertine floor. Even after polishing with 800 grit diamonds still looks bad. Used enhancer to darken scratch and improve appearance. Looks a lot better to me.
Light colored granite counter tops are susceptible to oil stains. The only way to remove the stains is to apply oil stain remover and let sit for 24 hours. The solvent in the remover mobilizes the oil and draws it up into the paste which is then vacuumed up.
