Q. The grout on my ceramic tile floor is discolored. I tried cleaning it, but the colors are now different. Is there a way to color the grout?

A. Grout color sealing is a perfect solution for you. Most tile and grout cleaning companies offer this service now. One major caveat: you want to be careful to use a company that uses a quality color seal product. Some companies are out there selling this service but are using a product that is tantamount to acrylic house paint. The problem with this is that even though it might look great immediately, in a short time it starts peeling and looking worse than before the service was done. Plus, paint-type color sealers won't have the other advantages a quality color sealing product has, such as:

Constant acting mildewcides (think about the bacteria that grows when foods and drinks, not to mention other accidents, illnesses, etc. penetrate into unsealed grout...)
Long lasting -- 5 + years generally
You can literally pour things like soy sauce directly on your grout and wipe it up.
You can change the color of your grout completely... even from dark to light.

Before hiring a grout cleaning company, be sure to do your homework and ask questions.
