WP-DC6 hinge screw rust

[Kbach]

I've got some rust appearing on the hinge screws to my WP-DC6 housing. I wipe the housing and blow around the srcew following each dive, but obviously missed some moisture. So....2 part question.

How do I get rid of the current rust and how do I prevent further rust issues?

Well, just me, I would remove the hinge screw and clean it with mild acid. You need to force water into the hinge area as a gentle stream to flush the area completely of water/salt and then blow it dry if possible.

Whatever you do, do not put "oil" on the screw. The acrylic will not react well to petroleum.

Maybe replace the screw with a new one.
