Oxygen Bleach Key to Cleaning Tile Floors by Tim Carter askthebuilder.com
Oxygen bleach is non-toxic, doesn't produce harsh fumes, and is color safe and fabric safe.
It removes all food and grease stains with no or minimal scrubbing. The oxygen ions in the solution attack the stain molecules, breaking them into pieces that rinse away with little effort.
To clean floor tiles, all you need to do is mix any high-quality oxygen bleach, with warm water and stir it until it dissolves. The next step is to pour the solution onto the floor tile so the grout lines are flooded with the solution as if you had spilled a glass of water. It's best to apply the oxygen-bleach solution to dry grout so the solution soaks deeply. Let the solution sit on the grout for at least 15 minutes allowing the oxygen bleach to work on its own. If it completely soaks into the grout, add more solution making sure there is always plenty of the cleaning liquid on the grout.
Cleaning grout doesn't have to be a battle. The longer you let the solution sit on the grout, the less work you have to do cleaning tile flooring. The oxygen ions work for up to six hours. To get maximum cleaning results, it helps to scrub the grout lightly after 30 minutes. Always pour new solution onto the grout as you scrub.
This stuff is as close to magic as you can get. It will remove red wine stains in minutes. Beet juice is not a problem. I've not discovered one stain it can't remove. Friends have tried the tile cleaning machines, but they say the oxygen bleach does a much better job. You have to always scrub a little, but that's how anything gets clean. Mechanical agitation of any surface is almost always necessary.
Once you have clean floor tiles, you can keep the grout looking like new by just adding oxygen bleach powder to your mop water. Apply a liberal amount of mop water to the floor scrubbing the tile surface with the mop. But leave the mop water in the grout joints without rinsing the floor. The oxygen ions clean the light dirt in the grout without scrubbing. Come back 30 minutes later and rinse the floor with clean water. If you do this each time when cleaning your tile floor, you'll never be on your hands and knees again with a scrub brush..
