>Tannish gunkLike makeup or skin oils? I clean my cameras with iso alcohol and acetone. Face pads and -pointed- q-tips are really good tools. Before you use the camera check:
Shutter fires on all speeds
Lightmeter works (check against a phone app)
Lightseals are ok
Viewfinder and mirror are ok
Then check back in. Congrats faggot have fun.
