When our wife Dawn and I bought our house, all of the tile, hardwood, and carpet was brand new. The pale faded white tiles in the living room all had a fresh, clean pale white grout as well. The living room truly sparkled and gleamed when it was empty. After living in the condo for multiple years, Dawn and I began to notice the discoloration in the living room grout. All of the grout was turning grimy and dirty. Instead of a fresh and clean pale white color, the grout was a dingy light brown. Dawn and I contacted a couple of janitorial services and all of us found a corporation that offered tile floor cleaning. Their tile floor cleaning repair was genuinely lavish. They charged their rates according to the square footage of the section cleaned. I thought that was satisfactory, given the fact that many people have larger living rooms than others. The janitorial repair used a unit to clean off all of the tiles… He sprayed something on the grout as well. After a while, the guy used a pressure washing unit to clean the tiles and the grout. The unit used water to clean off the floor, however it had a suction program that kept the water in a separate compartment. The professional tile guy removed all of the aged discoloration from the route, and by the time he was finished, our living room looked brand new. Dawn and I made an appointment with the same flooring corporation and next month all of us are going to get them to clean all of our carpets and replace some of the aged tiles in the ninth bathroom. Our kids have torn up that bathroom.
