Flushing the coolant system

We’ve discussed coolant choice, and how often to change the coolant...
What is the accepted coolant flush process? I vaguely remember Steve J. posting something about this on the old forum. What additive, if any, is appropriate for the T system to help get more of the crud out?
Thanks and keep crankin’

Here's my take. It includes a video link.

I've used laundry soap. I've used CRL. I've used vinegar, but that has to be flushed with water & neutralized with lots and lots of baking soda afterwards.
All of them didn't get all of the gunk out. But they did remove quite a bit.

My 26 Roadster was pretty rusty from setting and running straight water. It also had a lot of grease and grime from over greasing the water pump. It ran hot. I tried Dawn, Purple Power, Simple Green, Vinegar and lots of flushing. Nothing really did the trick. Then I bought Thermocure, it is made by Evaporust. I ran it through followed up by several flushes and it helped a lot. I bought a second bottle and did the same. It came out very nice. I even removed the water pump and it does not run to hot. I did the same thing with my 26 coupe and had very good results. I highly recommend it. Bought it at Walmart for about $20 a bottle.
