Cleaning the PVC chicken waterer is a relatively simple and straightforward process. Firstly, you should remove any debris or dirt from the surface of the waterer with a damp cloth. If needed, use warm soapy water to scrub away more stubborn dirt and grime. Then rinse thoroughly with clean water and allow to air dry completely before refilling it with fresh water. Additionally, if you want to keep your chicken's drinking area extra clean, you can use an anti-bacterial spray on both sides of the waterer every few days for optimal hygiene.
