No—I haven’t seen that discussion, and would like to. What is TSP?
Tri-Sodium Phosphate
Phosphates are banned from laundry and dishwasher detergents in many areas. Most manufacturers have gone to nationwide formulations, so all areas get phosphate-free product.
You can still manage to buy real TSP as a painting prep cleaning chemical, but you have to be careful you are getting the real stuff. You then add a little to your dishwasher or laundry detergent.
Here are a couple of recent threads on the topic.
