Grout is usually made of either Portland cement or epoxy and furan resin. It is applied in the space between two tiles in order to hold them in place. The grout surface is very porous and can easily absorb dirt and grim, which over a period of time leads to discoloration and appearance of dirty stains.
Though a number of commercial tile and grout cleaners are available, many of them are loaded with chemicals that are not eco-friendly and are supposed to pose health hazards. In recent times, cleaners made at home are gaining increasing popularity and many of them are equally effective in removing stubbornly stuck stains.
Making a Grout Cleaner at Home
Such regular cleaning will prevent accumulation of dirt and grim on the tile and grout surface. However, if your tile grout is not sealed properly, then even regular mopping can stain them.
Salt, Baking Soda, and Vinegar
A mixture of salt, baking soda, and white vinegar is also effective for this purpose. Take equal parts of all these substances and make a fine paste.
Then, scrub the area with a stiff bristled brush and rinse with water, or use a damp cloth to wipe away the solution. Do not use metal brushes for scrubbing grout and tile, as this can cause considerable damage.
It can also be mixed with baking soda to make a paste, which should be left for a few minutes on the surface, after which a little scrubbing is required. Then it can be cleaned with water, but keep in mind that bleach should be applied in a well-ventilated room.
For cleaning tough mildew stains, bleach can be directly applied on the grout after rinsing the area with some water. But bleach can sometimes discolor the grout, so testing it on a small inconspicuous area would not be a bad idea.
Just dilute hydrogen peroxide with water before applying on the grout and let it stay for a few minutes. Wash off with clean water. It can also be applied in combination with baking soda.
If these cleansing solutions fail to remove stains, you can also consider using a tile grout steam cleaner for cleaning. It will pull out the dirt and dust from the porous surface without scrubbing. You can also avail the services provided by professionals for grout cleaning and sealing.
