The best way to clean floor tiles

floor tiles

For the most effective deep cleaning, always use a PH neutral cleaner, a diluted white vinegar solution and orange oil.

The best tile cleaner for both bathroom and kitchen tiles depends on what type of tile you have and your stance on eco-friendly products.

Ceramic tiles and porcelain tiles both have very different cleaning requirements to natural stone for example, so it’s important to choose the right one for the job.

To clean bathroom wall tiles effectively avoid using harsh chemicals and consider using natural ingredient cleaners where possible. Most porcelain and ceramic tiles are pre-sealed during manufacturing which makes them easier to maintain, simply use a PH neutral cleaner and a non-abrasive cloth to wipe clean the surface.

Regular tile cleaning will make using natural products easier as sometimes they’re not as tough as chemical or solvent based products. A good way to clean bathroom tiles is with vinegar. Simply create a 50:50 diluted solution with white vinegar and water in a spray bottle and spray directly onto the surface. It can be used to clean soap scum from any surface including glass and tiles. All you have to do is buff it dry to avoid any streaks.

 

For tiles with a glossy glaze you should dust the surface of the tiles once every month, clean the surface with a non-abrasive cleaner and a microfibre cloth and then, for a streak-free finish, buff the tiles with a clean, dry cloth. If you’ve used a glass mosaic in your bathroom, make sure you buff them dry too to avoid unsightly water marks.

 

If you have chosen a textured tile, try using a clean, wet toothbrush to clean away grime and limescale in tight spaces. Cleaning textured bathroom tiles with baking soda is a great cleaning solution as it behaves like a paste, just mix 3 cups of baking soda to 1 cup of warm water and mix together. You can also use this mixture to scrub the grout

What is the difference between glazed and unglazed floor tiles

    What is the difference between glazed and unglazed floor tiles? Please check the following points.

    Glazed and unglazed floor tiles differ in their surface finish. Glazed tiles have a layer of liquid glass applied to the surface, which is then baked onto the tile. This process gives the tile a smooth, glossy appearance and makes it resistant to stains and moisture. Glazed tiles are available in a wide range of colors, patterns, and finishes, making them popular for decorative purposes.

    On the other hand, unglazed tiles do not have a glass coating and retain their natural, matte or textured surface. They are porous and need to be sealed to make them resistant to water and stains. Unglazed tiles are generally more slip-resistant than glazed tiles, making them suitable for areas that require more traction, such as bathrooms or outdoor spaces.

In summary, the main differences between glazed and unglazed floor tiles lie in their surface finish, appearance, and performance characteristics.
