Floors & Surfaces tips

  • Remove your shoes on returning home
  • If you have small children, clean floors with a disinfectant product
  • Do not use bleach-based products on carpets, wooden surfaces or small poorly-ventilated areas (risk of discoloration and irritant odor)
  • In case of having babies at home, take special care with their hygiene as well as with floors, or any surface they might be on.  At one year, the immunity rate of a baby is only of 17% compared with the one of an adult
