What amazes me is the lack of scientific validation behind most all of the articles you see online. The first and biggest no-no to tile and grout maintenance is using dish soap. Dish soap, pine cleaners and most all other household cleaners will make your floor get dirty faster. Even if you are doing a wash - rinse method it's impossible to fully rinse out the grout lines.
Most dish soaps are made from oil and other various chemicals such as triclosan, which is technically an organic compound. It has antibacterial properties which are a plus, but it has two downsides. It is very difficult to rinse, and it degrades very slowly. This means it would be tough to rinse out of the grout lines and once it's there, it would be there for a long while attracting soil. No matter how much you try to rinse the floor, the residue is still there. Another example would be lauryl polyglucose. This is a product that comes from corn. It helps the soap spread over surfaces. It's essentially an oil.
Also, I would not recommend using any bleach based solutions as they will do damage to the grout sealer leaving your grout vulnerable to permanent staining unless you have sealer impregnated grout.
As most all household cleaners will either leave behind residue or destroy most sealers you will want to find a good non-residue floor cleaner. Here are a few tips on how to use non-residue floor cleaners. Use them sparingly - not on every mopping
1. Vacuum tile and grout
2. Dry dust mop with microfiber head
3. Damp mop either with hot water only or with no rinse floor cleaner (used sparingly)
Be sure to wring out mop as dry as possible before mopping.
When you are ready to have your floors professionally cleaned you’ll find that super strong alkaline solutions are normally used to break down the soiling. Grout lines are then agitated with special pole mounted brushes. Then the floor is rinsed with high pressure and super heated neutralising water. This rinse process should remove all residue and further cleans the micro pits in the grout free from soiling.
Keeping grout lines clean can sometimes be challenging. Other helpful hints are not wearing outdoor shoes inside your home. If you do wear shoes inside your home be sure they are non marking shoes and the soles are clean. Don't walk on the tile floor barefoot for it will leave body oil on the tile face. Although you can wear clean socks.
I hope these suggestions and tips help you keep your tile and grout floor cleaner longer.
