It won't work -- putting aside the phosphates, it's a totally different formulation, because restaurant dishwashing machines run for 2-4 minutes, rather than 30-60. On the other hand, if you searched online, I'm sure you would be able to find the exact type of phosphate that was removed from dishwasher detergent, where to order it independently, and in what proportion it could be mixed together with modern dishwasher detergent powder, to restore the sparkly clean dishes you might have grown up with. You would also want to research the legality of such, as well as whether it would actually have any environmental impact or not where you live.
