Pourquoi votre sol paraît-il encore terne après le lavage ? — et le test de deux minutes qui vous l’explique.

a sticky or cloudy surface that attracts more grime and footprints.

One common source is using too much detergent or floor cleaner. The excess product does not fully rinse away and dries as a tacky layer. Another is the use of “shine-and-mop” products that contain acrylic polishes; these build up thin plastic layers that yellow and scuff over time, clouding the floor’s appearance.

To avoid residue buildup:

Always dilute floor cleaners according to the manufacturer’s instructions, never exceeding recommended amounts.
Rinse mop heads thoroughly between uses to prevent redepositing detergent.
