Ummm... how should I phrase it.... u can try that and tell us what results were...
I myself do the opposite - wait till the mud dries and try to pick it off... if all else fails u can always try the screwdriver solution
I got CatEye, and i can say many things about it, but not that its waterproof. those buttons are a pain too, and every time i go on trail and get it dirty they get stuck. Hey, BTW, does yours reset too on occasion? cuz thats what irritates me most - i dont keep track of the distance, (some guys i know even have notebooks in which they write down distance, average speed, even calories, heh) so every time it resets or freezes i just want to rip it off my handlebar
i dont ride with a computer! I guess im not that hardcore! But i am an engineer and if you get moisture on the P C B in behind a capacitor and freeze it it could pop it from the board also extreme temp. changes are not good for any electronics, it is not the water that is bad, it is the freezer. When you run you computer under water its warm(cold water is warmer than frozen water) and this could/will expand the soildered pins on your computer, then you are puting it in the frezzer, this will shrink them. These will be slight movements but it will only happen a few times before your computer fails, im just saying you shouldnt put your computer in the freezer
