My friend dropped, back first, his 4x5 Linhof camera in beach sand. Short of sending it off to have it cleaned, he was wondering if there were secrets to cleaning off all the sand. He tried masking tape and vacuuming with poor results.
Sorry to hear that. That is the reason that I never take that camera outside. I think it's way too sensitive. I bought a Toyo metal-field for out door work and kept the Linhof for the studio and architecture work. Not too much of a burden since much of the remaining equipment is interchangeable anyway.
