Porcelain tiles have a smooth and bright appearance, which is both a blessing and a curse. Clean porcelain tiles have a remarkable shine, but even a small amount of dirt can appear vividly clear against the contrast of the milky white or lightly coloured tile. By cleaning your porcelain tiles weekly, you can keep them looking their best.
You do not need to invest in a fancy tile cleaner or specialised porcelain product to restore a shine to porcelain tiles. Just squeeze 2 or 3 drops of mild dish detergent into a gallon of water. Apply the liquid to your tiles and grout using a dust mop (for floors) or spray bottle. If wiping your tiles by hand, use a soft cloth or sponge. Avoid using abrasives like scouring pads on your porcelain tiles, or etching may occur.
For Tough Jobs
For set-in dirt, grime and mildew, you will need something a bit stronger than dish detergent. Mix 1/4 cup of baking soda and 1/4 cup of clear ammonia inside a gallon of water and apply to tiles. Let the solution stand for about 15 minutes before rinsing. Ammonia has a very pungent odour but is natural and will not cause any physical or environmental harm (as long as you do not mix it with bleach).
Rust Removal Tip
If you have a particularly impossible rust deposit, attack it with a combination of citric acid and sodium chloride for maximum effect. Sprinkle some table salt over the rust and squeeze a lemon on top of the salt. Scrub with a soft cloth or sponge to dissolve the rust.
Shining Porcelain Tiles
If you really want to make your tiles shine, buff them with undiluted lemon oil. Dampen a soft cloth with lemon oil and wipe down tiles using rapid circular motions. For large areas, this may require getting down on your hands and knees for a bit of manual labour (since diluting the lemon oil with water will lessen the effect), but the results will be worth the effort.
