Bacteria in your grout lines:

If you have tile and grout in your home you maybe wondering if bacteria accumulates in grout lines or possibly the tile themselves. Grout is porous and minute particles will lodge themselves into the pores providing a perfect feeding ground for all sorts of bacteria, fungi, and viruses. If you have a natural stone floor, such as travertine, it too has pores that will collect and store food for pathogen growth. According to the most recent research there is more bacteria on a square inch of a tile and grout kitchen countertop than on a square inch of a toilet seat. Can you say YUCK!

How can you tell if bacteria is in your tile and grout lines? Well, if you watched a Steam Shark infomercial they use an ultra violet light to demonstrate bacteria is on the floor. Notice they never mention fungi or viruses. Of course they want you to buy their product and want to prove to you that it will kill bacteria. Because the Steam Shark heats water to 212 degrees fahrenheit the steam will kill bacteria because it is common knowledge that bacteria will die at 140 degrees fahrenheit. A simpler test you can preform on your kitchen counter tops is to spread a little hydrogen peroxide over your grout. If it begins to fizz and bubble it is killing "anaerobic bacteria". This is the bad bacteria that causes heart disease, gum disease, and many other illnesses.  Because hydrogen peroxide is mildly acidic, it has a pH of 6.5, you will need to rinse it down with an alkaline cleaner such as Mr. Clean to prevent the grout from cracking. If you have color sealed your grout or painted your grout DO NOT TRY THIS. Hydrogen peroxide is a bleaching agent and could bleach out the color.

When we clean and disinfect tile and grout we first use Sodium Borate in our cleaning solution. Sodium borate is not only a great disinfectant for bacteria but fungi and viruses as well. When the tile and grout are ready to be cleaned our water temperature is between 210-240 degrees fahrenheit. Because we are rinsing the tile with 2.5 gallons of hot steamy water per minute the floor is so clean you can eat off of it. Yeah, it's that clean. Why do you think we call it
