You might be asking yourself if dirty grout is really so bad. After all, perhaps that dark coloring is not so poor?
Well, if you decide to leave it alone, you're going to be damaging your air quality and increase your danger of slipping. Believe it or not, but clean grout increases the friction of a tile flooring by up to 35%. That is a noticeable difference!
Shower grout doesn't get a free pass. In its humid surroundings, it is a prime breeding ground for mold.
Calling a tile and grout cleaning company is your very best option for safer, clean, attractive tile flooring.
