Cultured marble bath countertops

Our cultured marble countertops have become yellowed in spots instead of the original cream originally. Can anyone tell me what has happened and if there is anything we can do to change "the look"?

    The yellowing may be because of heat. Coffee sitting on the counter or heat from curling irons. I am not sure you can do anything about that. Maybe a light sanding and polishing. I tried bleaching mine and it didn't work.

    Cultured marble does fade and yellow over time. Spots exposed to sun can fade quicker than others. Like Diane said, heat also can discolor the marble, as well as chemicals or cleaners. Once it discolors, you can't really fix it. There is a gel coat applied over the surface, and field repairs of the coating are not possible.

    Cultured tops are mostly "plastic" as the resin component is quite high. Surface "paint" jobs can cover the granite paint kits. Replacement is another more costly route.
