Mopping the traditional way generally ends up just spreading around dirty mop water. Using the system we recommend will be much more effective. Grout lines will stay clean longer also.
First, you'll need the proper mop. Lowes sells a Rubbermaid Microfiber Mop that will work well for you. Buy one of these and a couple extra mop heads.
Second, you'll need a neutral ph, no-rinse cleaner. Both Lowes and Home Depot have these available.
Mix the cleaner according to directions(more product is NOT better). I like to mix it up in a spray bottle. I spray about 100 square feet at a time and then mop it up. A light mist should work just fine if you clean fairly often. After spraying, just wipe it up with the microfiber pad. Change the pads once they start to show significant soiling.
This is the method that has worked best for me. It prevents slopping around dirty water and doesn't leave a film on the floor. Over-wetting and not changing out mop water often enough is the most common reason for dirty grout.
I don’t know you, but as a professional floor cleaner, I can tell you that Carpet as a flooring choice is not as popular as it was five years ago.
Today, many of the homes I go into only have carpet in the family/TV room and the bed rooms. The rest of the home’s heavy use areas are getting covered in woods, stone and ceramic/porcelain tiles. Makes perfect sense really. Most hard surfaces are easier to keep clean for the home owner, less prone to show wear compared to carpet and considering to the rising cost of the “fuzzy” stuff, a great investment for your home.
We saw this trend coming years ago and have invested a lot of time, money and education into learning how to properly clean, restore and maintain Stone and Tiled flooring. We are getting lots of phone calls from confused and frustrated home owners who are having issues keeping their stone and grout looking like new. In many cases, if the floor is under a year old, we can walk the home owner through a very effective cleaning process over the phone. If it’s been a couple years and just no amount of scrubbing and bleaching is doing it, then it’s time to call in the big guns at Blue Monarch. You will be amazed at what Steam Cleaning can do to bring that soiled Travertine, Limestone, Marble or snow white Grout back to normal. You have to see it in action to believe it.
