Weird corrosion on lugs in panel, advice needed
Hello all,
Had a pre-inspection done and inspector noted corrosion (somewhere in panel). I didn't see anything at first, neutral bars and service panel overall look new.
No water inside basement, 200-AMP service 11 years old.
And then, on close inspection, some of the lugs looked weird. I took a picture of the worst. I 'ranked' them 1-4, 1 being what i think is normal, 2 is normal+ some copper colored dust stuff on the bottom corner, 2 is more of that, and 3 and 4 include white stuff on the lug and green on the wire.
#4 is the worst by far in the panel, and oddly enough, is a double 30 AMP breaker with the top of the double breaker looking normal, wtf?
I popped one out and the buses look normal as far as i can tell. The little white cap things on the screws, about half of them seem in the process of falling off, a few are off.
Either way, i have to get an electrician out to sign off/fix. I was considering replacing some of the breakers myself (since i've done before) to save cost maybe. I don't want to get some junior in here telling me a need a panel replacement when it might not be necessary.
Advice needed!
Thanks!!!

That is definitely corrosion caused by moisture.
The panel may be dry now but it looks like it had been wet at one time.

Might be worth tracing that #4 wire back a little bit to see if water is wicking along it from somewhere. It's weird to see corrosion on just that wire and the one below it.
