Hummingbirds don't
like dirty feeders, not to mention old hummingbird nectar
can make them sick. So cleaning your hummingbird everytime
you make new hummingbird
nectar is important.
First, dump out
the old nectar. Then wash with equal parts of hot water and
cider vinegar. Allow to soak for a minute if it is very dirty,
and use a baby bottle brush to clean inside. Rinse well with
hot water and allow to dry upside down on a cloth before refilling.
It is important
to not use soap because the leftover soap residue can be harmful
for hummingbirds.
