How do I clean my feeders in winter? Cleaning feeders in winter can be challenging, especially in the colder climates where outdoor spouts need to be turned off in winter to prevent freezing. Here are a few tips for cleaning feeders in winter: Consider purchasing tube feeders that can be completely disassembled and washed in a diluted bleach solution in the kitchen sink or put in the dishwasher. Wash suet feeders and hummingbird feeders in a sink or dishwasher. Use platform feeders with removable trays that can be brought inside and washed in the kitchen sink or dishwasher. Use disposable “thistle” socks for feeding nyjer seed. Find more information about cleaning feeders and other tips for safe bird feeding on our website.
