issue I see with turps is that you're flushing at least some of it down the drain (oil and water don't mix), and it doesn't really act as a good haze remover either.
Saati IR26 as well as Easiway 701 are both excellent choices that are safe (in the quantities that a printer typically uses) to flush down the drain. They also work as excellent haze removers when used with a pressure washer (we haven't touched haze remover since we switched to them).
