Before tackling stains, it is essential to understand  their origin . They can be due to several factors:

  • Mineral deposits  : If your water is hard (rich in limestone), it leaves residues that accumulate and eventually  turn black .
  • Mold  : A poorly ventilated bathroom and ambient humidity encourage  their development  in the toilet bowl.
  • Bacteria  : Some microorganisms thrive in  humid environments , which may explain these dark marks.

Identifying the cause  allows you to adopt  the right method  to eliminate them effectively.

The natural trick: white vinegar and baking soda

No need to buy harsh chemicals  ! A simple, economical and ecological solution  can work wonders  :
