I can't imagine I'm the only person that dislikes the chore of cleaning out your solvent container when the solvent gets too murky and dirty. In the past I could use up to about 5 or six paper towels trying to clean the sludge that remains at the bottom after you've poured off the clean solvent to re-use.
Well here's how I get around that mess. I take a ziploc sandwich bag, I line the inside of my container with it and pour my solvent into the baggie. When the solvent has gotten dirty I pour the clean solvent into another container and the junk that remains is in the baggie, ready for me to just lift out, seal with the ziploc zipper, and just throw away. All that's left is a perfectly clean container. How awesome is that?
Take a look.
As you can see I use the traveling container that locks tight. It's great because the container has a cleaning plate with holes in it so the sediment goes right to the bottom and the clean solvent stays at the top ready to use. I've travelled with this container sealed shut with the baggie going over the lip as shown and with solvent in it and it has never leaked.
125 bags in one box will probably last me until I can't even lift a brush anymore. Try this setup. I think you'll like it.
