I use small sealable plastic tubs for very small components, and larger ones like takeaway food comes in, or old 2l ice cream tubs for larger bits so I don't get all 10L of cleaning fluid dirty every time.
I try and save really dirty greasy stuff for when the fluid is already getting a bit grottty, after cleaning the carbs this time I chucked my kickstar assembly and engine mount rails, nuts and bolts in - saved a lot of elbow grease and cleaning aerosols.
