When I airbrush, I use lots of mineral spirits to thin paint and clean the brush. I like to have control over how much is dispensed and avoid drips (which always happen when I decant fluids). Empty contact-lens saline bottles are perfect for dispensing controlled amounts of solvents cleanly. The cap allows single drops of liquid or a steady stream, and the large bottles hold ample amounts of liquid so they don’t have to be refilled often. A safety note: Clearly label what is inside the bottle so nobody grabs the wrong one.
