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  :

Method :

1. Prepare your mixture

In a bowl, mix:

• 250 ml  of white vinegar ( natural disinfectant and anti-scale )
• 125 ml  of baking soda ( cleaner and deodorizer )

As soon as the two ingredients mix,  an effervescent reaction occurs , ideal for  dissolving encrusted deposits .

2. Apply to the toilet bowl
