So please replace nectar and clean your feeders about every five days in cool weather, more frequently when temps heat up. When the thermometer reaches 90-100, it needs replacing every day.
Dispose of unused nectar and clean the feeder using white vinegar and hot water. Dry and replace with fresh nectar.
Make nectar using a 1:4 ratio, one part sugar to four parts water. Boil about three minutes. Cool. Store surplus nectar in a glass container in the refrigerator for up to two weeks. And skip the red dye, which is unnecessary and potentially harmful to the birds!
