AeroPod, PowerPod and Newton

I have been using the Newton on a couple of mountain bike races which have been generally dusty. Is there any protocol on cleaning the wind port and/or verifying that the wind port is clean and operating properly?

Thanks in advance.

There should be no problem, but if you want simply use a Dust Off air canister to blow the dust out of the port. There is a membrane in the port that keeps dust from impinging the wind sensor.
