Canon EF 20-35mm f/3.5-4.5 II USM Lens

This lens is is good condition, except that it is having problems connecting to my camera and autofocusing after some exposure to rain. I tried cleaning all the contacts that I could reach with alcohol, outside and inside, but it did not fix the connectivity problems. There is some slight, visible corrosion within that I could not reach and didn’t dare to. Comes with protective glass and hood.
