Good cleaner for metal tubes?

Heh there everyone!
Anyone got any suggestions for a good metal cleaner?
I'm currently working in the medical device industry in the manufacture of hypotubes. As part of our production process, the raw tubes need to be cleaned of oil that was applied to the tube in the drawing process. Our current cleaner is composed of 25-60% Phosphoric acid and <10% Surfactant. While this is an OK cleaner, the problem is that we are having to replace it too often and that is causing problems for our effluent treatment plant. We currently dump ~135 litres of diluted cleaner every day!
Anyone know of an effective oil-remover that would last longer than a couple of days?
