So far mine goes in the shower with me at the end of the day. Everything but tanks, which get hosed off. Rinse in the shower and then hang to dry. Easiest way I know to deal with sand and junk like that without getting it every possible place in the house.
Dump the stuff into a dive bag and/or tupperware storage crate to get to and from the dive then directly into the shower at the house.
