In a prior article, I pointed out faulty processes for maintaining a tiled floor with grout lines. We noted the D (floor) + D (mop) + D (solution) = Dirty Outcomes each and every time. It is impossible to clean a floor with dirty tools and solutions. Although we all recognize that truth, we do not always apply the concept in our day to day activities. The correct formula is D (floor) + C (mop) + C (solution) = Cleaner Outcomes each and every time.

I suggest you start fresh by bringing in an appropriate floor scrubbing machine/tool with the correct chemicals to get the floor back to standard. Consult with your distributor on how best to proceed. In most cases either a cylindrical brush system or an orbital unit (with appropriate scrubbing pad) will do the trick if used with the right chemical mix. Since there may have been attempts at “waxing” the floor to get a shine in the past, it might be best to test an area with either a strong mixed degreaser or stripper solution. Use a wet vacuum to pick up the slurry and rinse thoroughly. Inspect the grout lines carefully and repair/patch any cracks or missing matrix using a color that most closely approximates the current color on the floor.

Once the floor has been restored, consider applying one or more coats of penetrating seal to protect is in the future. Once this is complete, the floor should be kept swept/vacuumed with effort to pick up any spills immediately before they have time to soak in. As to mopping, I highly recommend a microfiber mop system with a neutral detergent with periodic rinsing with plain water to reduce chance of build up.

Remember, it is all about the process. What is your process?

Your comments and questions are important. I hope to hear from you soon. Until then, keep it clean...
