3. White vinegar against dirt between the joints
Our grandmothers used vinegar to clean just about everything, and they were right. Vinegar is one of the most effective natural products for cleaning and disinfecting surfaces, removing the most stubborn dirt.
Mix two equal parts vinegar and warm water and soak a cloth in the solution. Clean between the joints and, after a few minutes, wipe with a clean cloth. If the stains are old and do not come off, apply a little undiluted vinegar for a few minutes before cleaning.
4. In extreme cases, water and bleach
If the natural alternatives listed above do not give satisfactory results, there is only one way out: use bleach.
Wear gloves and pour 3 or 4 tablespoons of bleach for every liter of water. Use the solution to scrub between the joints with an old toothbrush and, after about ten minutes, wipe with a clean cloth.
Keeping your floor spotlessly clean and removing dirt between the joints is easier than you might think: immediately apply the tips described above to restore the floor to its original appearance.
