I read with interest the post about taking your 5D for a dip in the saltwater. I don't think and would hope that I never do that, but it did get me to thinking. My new 24-105 had some finger marks on the zoom ring so I decided to give it a bath. It has never worked better.

One word of warning to everyone, this only works with soapy water and the hotter the better. But don't forget to let it dry.

I would suggest that any mug could do this.
Thanks for viewing.
