Mold
is very bad in hummingbird feeders. Remember to change the nectar in
your feeder every 2-4 days, regardless of whether the nectar has been
used. In hot, humid weather you might even have to change the nectar
every other day.
I find the more often I change the nectar the
easier it is to maintain the feeder. You won't be battling any black
mold and you'll have a lot more hummingbirds and orioles.

To clean the hard to reach places you can use a pipe cleaner or we have special little brushes for cleaning feeders at Wild Birds Unlimited.
Now that we are in the hot and humid weather, you should soak the hummingbird feeder for about 5 minutes in a Scoot,
active enzyme cleaner once a week. Or use a one part vinegar to nine
parts water solution to clean the feeders. Then rinse your feeders
thoroughly.

What a wonderful place to work! I visited Giverny last week, but was horrified by the crowds. Must be quite a factor for the gardeners to consider - the sheer quantity of people moving through the garden each year! But I'm sure that working there is quite different because you get to enjoy the garden during the quiet times.
