I take all my crap off in the shower. and just jet the shampoo and soap fall on the suit and everything while its laying on the tub of the shower. Then just hang to dry.. if the boots are nasty still just fill up the inside with some detergent and water and let them soak during lay day.
a foamy mixture of shampoo and soap probably isnt the best thing for your wetsuit. i'm not an expert but i read there's a chemical that can wear down the rubber. when i rinse my suit out i use dish soap
I found this article by just googling "wetsuit cleaning" http://www.awoosh.com/DocVikingo/Cleaning_Smelly_Wetsuits.htm
