It is recommended to clean the ceramic once a month.
Place the tray in your clean sink without blocking the drain and cover the ceramic with tap water mixed with white vinegar (a glass of white vinegar). Let it drain, repeat the operation 2 to 3 times using only tap water. The white vinegar must completely disappear, so do not hesitate to rinse the ceramic thoroughly to remove the vinegar smell. Take a new non-abrasive sponge and pass it over the ceramic and rinse thoroughly. Warning: be careful, vinegar water must not pass through the filter cartridge, otherwise you risk stripping the cartridge and your water will be undrinkable.
