In the warmer months, feeders will need to be cleaned more often. If it's hot, windy, or rainy out, clean the feeder every one to three days. During colder, dryer months, clean the feeder every four to six days., Watch the nectar closely and throw it away when necessary. How long nectar lasts depends on your region and climate. When the nectar appears cloudy and white, it needs replacing.In some cases, nectar can go bad in only one to two days.
 The feeder should be cleaned regularly with a mild cleanser. However, once a month you should deep clean it with bleach. This is particularly vital if you notice black mold growing on the cleaner.
Clean the feeder at the right frequency, depending on the season.
Replace the nectar regularly.
Deep clean the feeder at least once a month.
