I "decant" it out of the pickle jar and into the gizmo. Then I pour the gizmo out into a second picklejar (wider mouth jars obviously work best). If there's any settled stuff left in the first jar I'll decant all of it along with a little grunge into the newly filled jar and swish up the grunge in the first jar and pour that into a container that will eventually be used to transfer the whole lot to the paint recycling depot. So at any one time I've got two jars and a jug of grunge soup going. It's not as bad or complicated as it sounds.

If you use one jar just pour out the gizmo into a bowl and then pour the dirty stuff back into the clean stuff. IN a couple of days it'll have settled out again.

I never mentioned it but I find that I need to do three washings with the gizmo with a paper towel to blot away the dirty solvent on the chain. The final of the three is done using a little bit of fresh clean mineral spirits. With a little going into the jug each time and a little coming from the fresh supply it all works out quite well.

With this method and having to keep somewhere around 10 motorcycle and bicycle chains cleaned I find that a gallon of mineral spirits lasts me a good 6 or more months. And that's even using it as well for some small parts cleaning of all these vehicles as well. So you can see that overall it's pretty frugal. If you're only using it on a bicycle or two and don't have all the other hobbys that I do I don't see why a gallon of the stuff won't last you easily a year of chain and parts cleaning if you only use what you need.

Oh, and the parts cleaning spirits goes into the settling jar as well. So it gets used over and over again as well.
