High traffic gradually dulls the floors and the grout becomes dark with dirt. Regular mopping only removes surface-level dirt. To keep the tile floors in your property looking their best, we recommend having them professionally cleaned every year, depending on the amount of traffic, soil and regular floor maintenance.
Stay off freshly cleaned tile floors for at least 30 minutes. If the tile & grout was sealed you can walk on floor within 60-90 minutes, but avoid getting any liquid on the floor for 24 hours until the sealant cures completely.
Since grout is a porous material, it can easily absorb spills and other soils. Sealant creates a barrier that protects the grout from dirt, grime and spilled liquids. This gives you additional time to clean it up before it can become absorbed, making the grout much easier to keep clean.
Grout is a porous material; this means it can easily absorb what is sitting on top of it. Like clothing, the longer a stain sits, the more difficult it is to remove. While a lot of discoloring/staining may come clean through the deep cleaning process, there are options to re-color the grout to make sure it all looks the same.
