Maybe consider part of a CIP (Clean In Place) process. Something like 5% solution of caustic (sodium hydroxide) heated to 70-80ish deg C if I vaguely recall. Pass a given volume through then rinse with a given volume of clean water. The process is amazingly effective in cleaning out organic residuals in stainless steel food production lines although there are probably more steps to it in a large scale industrial plant.
