NEW garbage can for soaking (no tub in the house). Bought a heavy duty 50 gallon or so, rigged a garden hose tap at the bottom with a bulkhead adapter so I could drain it. Good for soaking my BCD, regulators, computer, knives, camera rig etc for 24 hours after an ocean trip. After lake dives I just rinse with the handheld shower. Make sure to rinse the inside of the BCD bladder.
Wetsuits, hood gloves etc go in the front load washer on the Rinse and Drain cycle at on gentle and slowest spin with some Sink The Stink. Hang to dry. After every ocean dive or once every couple of months of fresh water diving.
