Hi! So our little birdie friends are leaving messes on the deck that can't be cleaned with a broom. I can't power wash and don't have access to an outdoor water source. We rent, and have downstairs neighbors. I don't want to be a jerk and create a mess for the people downstairs. What's the best way to clean out here without being a nuisance?

The deck is wood, and there are gaps between the slats that are about 1/2" apart.
