As a rule, always use a microfiber cloth to dry the surfaces so as to prevent hard water spots from forming.
Always comply with the action times specified on the packaging of the detergents and do not use different products at the same time. It is advisable not to use any type of abrasive detergent, alcohol-based detergent or strong acidic/alkaline detergents (e.g. detergents containing hydrofluoric acid or basic solutions such as caustic soda), nitrous solvents and acetone.
To make sure that ceramic retains its properties unaltered over time, wash it on a regular basis with water and a non-abrasive bleach-based detergent (gel, cream or spray), using a soft sponge to remove soap residues and prevent the formation of limescale. While cleaning the interior of the toilet bowl, always leave the seat and cover raised to prevent the fumes from damaging the surface of these parts.
Limescale deposits may be removed with white vinegar or other vinegar based products.
For White, Coloured, Matte and Glossy ceramic ware, cleaning procedures and products are the same.
