Hi BettyRubble:
I can empathize with the stinky neoprene as I dive most exclusively in the ocean, drive home takes about 2 hours, and then by the time I get home, cleaning gear is pretty low on the totem pole. So the next day (or maybe the day after) I get around to cleaning my gear and it is super funky!
I use a 100 gallon watering bucket for livestock, it's Rubbermaid and you can pick them up at a local Agricultural supply or
Tractor Supply Company, usually for less than 100 USD. I fill it with fresh water and then clean my gear a piece at a time by agitation and rinsing and using no cleaners. I toss everything in the tub to soak (regulator with tank included) while waiting to be cleaned.
Afterwards, I hang everything that is hang-able on my
gear hanger. The UK hangars work wonderfully, and even in shade offer warmth and ventilation necessary for non-stinky drying. You can make a gear hanger for cheap and if you don't have a garage or shaded front porch, you can just put the rack in your bathtub! Within a day all of your gear will be clean, dry, odor free, and sparkling clean- ok maybe not sparkling but you get the idea.
I hope this helps and good luck.
With kindest regards,
Thomas
