tile cleaning tips in San FranciscoThe Leading Cause Of Discolored Grout Might Surprise You

If your grout continues to look dingy and dirty no matter how often you clean it, you’re not alone. In fact, for many San Francisco homeowners, it can be frustrating to figure out exactly how to prevent your tile and grout from looking dirty, dingy, and most importantly discolored. As a top-rated tile cleaning service in the Bay Area, we want to help you combat grout discoloration by attacking its main culprit. Here is a breakdown of what’s causing your grout to look nasty and gross.

Ineffective Cleaning Leads to Discoloration

We bet you thought that the leading cause would be something obvious like dirt and spills. But amazingly, the residue left behind by ineffective cleaning products and methods is what causes grout discoloration. This is because grout surfaces are extremely porous and set lower than tile making it the ideal spot for residue and dirt to settle. 

When too much moisture is used in the tile and grout cleaning process, grout can become dirty exponentially faster—and stay that way no matter how much scrubbing and mopping you do. 

That’s why utilizing professional tile and grout cleaning services is so important. North American Chem-Dry has professional-grade equipment that’s strong enough to extract dirt from grout without depositing sticky residue. We also refresh the protective sealant on your grout in the process—making it more resilient to stains.
