Over time, travertine takes on a natural patina, also known as antiquing, which is a darkening of the stone. Some people consider this darkening to be aesthetically appealing, especially in a design scheme with rustic elements. However, to other people this natural darkening of the stone makes the stone seem dirty, and they are not pleased with the appearance of the stone. Sweeping and mopping can never remove patina from travertine.
Professional stone restoration contractors can clean, hone, and remove a very thin upper layer of the travertine, to reveal the brand new stone underneath. We stopped during our process to take this picture, which demonstrates the difference between the floor as it was when we arrived, and the floor after removing the darkened layer.
