I have a quick question for everyone.

My wife's new X5 is ceramic coated. The car gets bird poop on it at work, it could happen on Monday, Friday, or anywhere in between. Anyway, the only time I get to hand wash it is on Saturday. So, my question is, would it be better to potentially let the bird poop sit all week or would it be better to go to a brushed car wash?

I appreciate your advice, thank you.
