Why is grout so difficult to clean?

Grout is made up of sand particles, making it easy for liquids to pass through and dirt to collect on the surface. According to The Grout Guy, Brian Mcauliffe, there’s actually a simple solution to keep your grout from staining in the first place.

“Cleaning is the first step to preventing the mildew from ever establishing. Water in the bathroom may evaporate but dirt does not and soap film is the biggest culprit as the dirt clings to the scum left on the grout. The key is to clean your tile two to three times a week with a cleaning product that is made for removing soap scum,” Mcauliffe told TODAY Home.

Some great products are available at your local grocery store and do a decent job at fighting soap scum, like dish soap, Clorox Bathroom Cleaner and Tilex Mold and Mildew Remover.

Once the soap scum has been removed, it’s time to tackle the stubborn stains and whiten the grout. Becky Rapinchuk, from Clean Mama and author of the book "Simply Clean" recommends "a simple combination of cream of tartar and lemon juice."

"This method takes a little more elbow grease but it works really well to remove some of those surface stains in the grout as well as naturally lighten the grout,” she said.
