The fast concludes at 6:11pm.
One washes Netilas Yadayim (covering the entire hand with water) without a Brocho, and rinses one’s mouth as soon as possible after Maariv, and certainly before Kiddush Levanah or breaking the fast.
Kiddush Levanah is recited if the moon is visible. Ideally, one should first change into leather shoes, rinse one’s face to freshen up, and taste something, unless this will negate his participation in a Minyan.
The Beis Hamikdash was set ablaze on the afternoon of the 9th of Av, and burned through the 10th. Therefore, the custom is to extend all restrictions of the Nine Days (including – but not limited to – consuming meat or wine, having a haircut, bathing, wearing freshly laundered clothing, or doing the laundry) until midday (12:25pm) of the 10th of Av.
