This stuff is pricey compared to say, window cleaner but, that is because it is the perfect thing for cleaning alclad out of your airbrush. If you have an appreciation for quality airbrushes then you already know the first rule about maintaining a good airbrush; don't take your airbrush apart! This cleaner loosens up crusted alclad on the on the outside of your airbrush in one pass and flushes out alclad from the inside of the airbrush in just one or two rinses. WARNING! Be careful not to splash any of this cleaner onto your model! I accidentally spilled some on my MG Barbados inner frame and left it to air-dry for fear of smudging the paint job. Tragically I later discovered that the spilled cleaner had fused my model together everywhere it touched it. I broke the arm right off just trying to move it and several joints are bound fast together and immobile. As a result I'm having to order a whole new kit and start over completely! So don't be like me and throw away your hard effort, time and money. Don't spill this on your model.
