Villeroy & Boch ceramic sanitaryware has a smooth, dense and virtually scratch-proof surface that is resistant to all common household acids and alkalis. Clean water and a damp cloth are often all you need for everyday care. Water marks, residual grease or soap can be removed easily using a bathroom cleaner or vinegar-based cleaning product. If you would like to avoid "chemicals" entirely, you can use household vinegar or diluted vinegar essence to quickly remove limescale marks. For more stubborn stains, soak a cloth in vinegar and place it over the stain to work overnight. You can also find mild limescale removers or vinegar-based cleaners at specialist retailers which should be used according to the cleaner manufacturer's recommendations. Particular caution is required with substances containing high amounts of fluorine (e.g., rust removers or toothpastes). If they are not removed, they can lead to the formation of stains. Make sure you wipe them off immediately! For heavier contamination, we recommend a non-abrasive liquid or cream bathroom cleaner. For even more effective results, apply the product using a soft, non-scratch sponge.
