A mild, natural detergent should be used for cleaning. Then rinse with water and dry with a soft cloth. Do not use any corrosive, abrasive, chlorine- or acid-containing or active oxygen-containing agents! Toilet seat and fastening parts must not come into contact with toilet cleaning agents. Please leave the seat and lid folded up as long as there are stronger cleaning agents in the toilet bowl. Note: Scent blocks in the bowl can cause discoloration!
