Corrosion on Intake Air Bypass (IAB) lines

I have noticed a lot of corrosion on the vacuum lines to my IAB solenoid valves. See photo.

Has anyone experienced problems with this system due to line corrosion?

Does it snow a lot where you are from? If so, do they salt the roads? If so, that could cause the corrosion/rust... Try spraying some PB Blast on it and wiping it off, other than that, you may have to have the lines replaced.
