We have 2 of the older square/cube shaped Seattle Sports collapsible sinks (one for washing, one for rinsing).  I'll heat water if I'm motivated but I don't budget my fuel for heating dish water so it's unfiltered lake water for the most part.  Sometimes, again, if I'm motivated I'll fill the sunshower but tripping in May and June doesn't always guarantee hot water.  Washing dishes is not rocket science (is it?).  Un-eaten food, if there is any, is burned.  I once buried un-eaten food but it was dug-up that night by something?  I don't bring a tape measure re: my distance from the lake but I feel like we're far enough away most of the time.  I don't recall ever digging a hole for my dishwater.  I can usually find an uprooted dead fall to dump it in or it's cast over a wide area on the forest floor.  Sorry if that offends any of you.  Also, I sometimes rinse my coffee cup in the lake since I'm typically fishing when I drain the mug.  To be honest, I'm not real concerned about my "efficiency" in anything when camping but the sinks are a nice tool that we have gotten a lot of use of.  Seriously, why over think it.

Tim, I think you will like using a sink for no other reason than it gives you a tool to do something that needs to be done anyway.     I've never got sick from my utensils but then again, Yukon Jack is 100 proof.

Gosh! Page 5 and not a bucket user in the bunch. When solo a small pan of hot water is used when dishes need to be washed. On group trips one bucket for washing and another with cold lake water with a little bleach added for the rinse and then air dry. I prefer Dawn detergent and really hot water. I needed a new scrubber and ended up with one that had a handle. It seemed like extra bulk until I found out how pleasant it was to use with scalding hot water. A pail of warm water and a bowl for pouring the warm rinse over my head to wash the suds away on a chilly day is a nice extra. No need to lift the whole bucket over my head. I was gifted a 6.5 gallon bucket at the Quiet Journey dinner and am getting my kitchen packed in it for the next trip.
