I have used carburetor cleaner to soak tips and air caps for several years with good results. The cleaner I used was dark and when stirred it turned white, cloudy looking. The last carb cleaner I bought was almost clear, and no good at all. I was just wondering if anyone uses the good cleaner and what brand it is, so I can find it again. We use CV and always clean up with lacquer thinner. The carb cleaner was just used periodically, mainly for the dried stuff.
From contributor M:
Carb cleaner is close... The stuff that really works is (go figure) Spray Gun Kleener. It's available in singles (shake first), a 5 with a basket in it, or for the hardcore, 5 gallon cans. If you use it, make sure that soft seals are removed first and set aside. Do not soak soft seals that might be needed later. Teflon or any profluorocarbons will be fine. After soaking, rinse your stuff off with lacquer thinner and blow parts out with compressed air. You will be really happy with this product. I get it at automotive paint jobbers around the Detroit area.
