Plasticware should be cleaned with a soft cloth or sponge in mixture of warm water and a non-alkaline detergent. Avoid all alkaline detergents and abrasive cleaners or pads, they have a tendency to weaken plastics, especially those made of PC (polycarbonate). After cleansing, the items must be thoroughly rinsed with tap water to make sure no detergents remain. Then rinse with distilled water and let dry. To prevent leakage, disassemble spigots and closures to clean threads and remove excess salts that build up over time.
