When cleaning out, how much solvent should I use?
First, do a 3–5 minute suck back to retrieve as much of the material from your pump and bars as possible. Then, still sucking back, take a 20oz Coke bottle full of solvent and have one end of the bar suck in a few ounces to release the residue left behind. On the other end of the bar, do the same thing. Place the remaining solvent in the pump. This is ALL you will need for the day.
