Overcoming flour or other nonmagical ways to defeat invisibility


I am looking for ideas on how to defeat a flour trap. As a rogue, I rely on sneak attack to really damage my foes. The plan for taking on the BBEG is the party will make me invisible with our wand of Greater Invisibility. However, I know the enemy has set up several flour traps and uses telekinesis to disperse the flour into the air, making invisible creatures immediately visible.

However, flour is tricky. If you get it wet, it does not clean it off. Instead, it only makes it sticky. How could I overcome a flour trap and resume my invisibility? I think my DM is doing this because we have used flour against invisible creatures he’s sent after us, and I think he is hoping we come up with a clever way of defeating it so he can use that same thing in the future. So, I’m not entirely sure I want an answer, lol.

To make this question more specific, we have at our disposal a cleric, a wizard, and a fighter. The cleric can prepare Create Water, but that will not help. Prestidigitation only clears one cubic foot per round, so the greater invisibility will wear off before the flour is entirely cleared. Is there anything that can clean an entire five foot square in a single round?
