Was shooting near the coast in Oregon recently. There was a light drizzle the entire time, but my 5D3 + 24-70 f/4L IS handles that just fine -- so I thought nothing of it.

However, when I looked at the camera the next day, it wasn't just rain. It had white residue (surely salt) over the focus/zoom rings of that 24-70. Some very stiff winds must have also kicked up some sea spray and it promptly dried out. The lens was filtered the whole time, so I doubt any direct fluid ingress took place -- I didn't take any direct hits from a wave or anything.

So I traveled back home today and will promptly bag + desiccant the body/lens combo shortly. Any best practices to get the residue off before it goes in the bag? Warm wet cloth? Some form of cleaning solution?

Thanks!
