What is the optimal system for chair maintenance in regards to flushing lines?

At the end of the day, flush two litres of water through the lines, then use Orotol and allow to sit in lines as instructed, then flush one litre of water through the suction. Once a week preferably on a Friday at lunch, use a detergent such as MD555 to let sit for one hour and then flush with one litre of water.
