How to clean floor tiles naturally

Cleaning grout on your floor tiles in a tub/shower enclosure is easier than cleaning the wall tiles in, say the kitchen back splash, since you don’t need to worry too much about making a mess on the counter top.

The procedure:

Dampen the tiles and grout with a little warm water. You don’t want to flood the place, just enough to make a thick paste and hold the baking soda in place.
Sprinkle the baking soda evenly on the tiles, about the thickness of a dime.
Use a stiff bristle brush to work the baking soda into the grout lines.
Let the paste do it’s job for about ten minutes.
After you let it sit for a little while, scrub again to get the loosened soap scum off of the tiles and grout.
Rinse with warm water.

How to clean wall tiles

When cleaning the grout on wall tiles, you will need to make a paste with the baking soda so that it sticks to the walls. This is where the measuring cup comes in handy. If you are working above any sort of natural stone or wood, like a counter top or floor, you will want to cover it with plastic to prevent the baking soda from coming into contact with the material, since it may leave a stain.

The procedure:

Pour enough baking soda into the measuring cup to cover the area you need to clean. I’ve found that a cup covers about 4 square feet. So, for example, if you need to clean the short side of a bathtub wall, it’s about 2.5 feet x 6.5 feet or about 16 square feet so you’ll need about 4 cups of baking soda to cover the whole wall. For just the grout, you won’t need this much, unless the tiles are very small.
Mix the water into the baking soda until it becomes a thick paste. A 2 to1 ratio of baking soda to water should be about right. So, if you need a cup of baking soda to cover the area  you are working on, use about a half cup of water. You are looking for the consistency of toothpaste.

Cleaning the grout

Fill a spray bottle with warm water. Dampen the walls lightly using this. This helps activate the baking soda when you apply it to the walls.
Apply the baking soda to the grout using the stiff bristle brush. Cover it with a layer about the thickness of a dime.
Scrub the grout lines and let the baking soda do its job for 10-30 minutes.
If the grout stains are bad, the longer you let it sit, the better the results will be.
Scrub again to remove the loosened grime from the grout.
Rinse with warm water using the spray bottle.
Wipe to a shine with a damp microfiber cloth.

Just a precaution:

Baking soda has a pH of about 9. It is not by any means an abrasive or harsh cleaning agent but in the best interests of your natural stone or wood finishings, you should always test a small section before attempting to clean large areas. If the stone or wood surrounding your grout is not sealed properly, it may cause staining.
