[Function and Operation] The main function of the bird bath cleaner copper tray is to keep birds' baths clean and refreshing, thus reducing the need for frequent scrubbing. For daily cleaning, simply remove droppings, fallen leaves, and other debris, thoroughly rinse the bird bath, and then refill with fresh water. However, a deep cleaning once every week or two is still essential! [Compatibility Notes] The bird bath copper tray is only compatible with non-metallic basins, including stone, plastic, nylon, or composite materials. Do not use with metal basins (alloys/iron). Metals react with copper ions, neutralizing the effectiveness of copper. [Natural Water Cleaner] The 99.99% pure copper bird bath basin (0.8 mm thick) utilizes the inherent properties of copper to maintain cleaner water in the bird bath. "This product cannot replace regular cleaning or water changes." [Effective Design, Maximum Contact] The bird bath copper tray features a three-point support design to maximize surface contact with water, keeping the bird bath clean and refreshing. Say goodbye to frequent and tedious cleaning of slippery, green bird baths. Using the copper dish, the cleaning interval can be extended from approximately every 3 days to approximately 14 days, saving you about 120 minutes of cleaning time per month. [Money-Saving Tip] The 0.8mm thick copper bird bath dish provides powerful purification. Simply place it in the bird bath tub to get started – no need to buy various cleaning tools.  [All-Day Effect] The copper dish surface undergoes a special passivation treatment to ensure its physical purification effect remains consistent throughout the year, unaffected by weather conditions. It won't interfere with any fountains or heating equipment you might use. This makes it a reliable water purification tool year-round.
