This is an example of how salt blasting can clean glass tile with no damage. This is a new tile to the market and only had two years of build up. A competitor turned down the job because their process will damage or burn the glaze. We jumped in with our Salt Blasting equipment and had the tile looking new with NO damage in about an hour. Glass tile is becoming more and more popular and for good reason. Its beauty is second to none. Glass pool tile is a great choice to accent your swimming pool and or backyard. Just keep in mind that glass tile is high maintenance then say ceramic. Glass is soft and can be etched by water over time. There has been many cases were a water stain can be seen after cleaning. If you have glass tile in raised areas such as spill ways and or dam walls the sun too will damage the glass over time. Food for thought. If you have any questions feel free to call. We will do our best to help. Thanks again to Jim for the work and we will see you and Rex (their dog) in a couple years.
