Ok. I bought some Mr Clean cleanser + disinfectant liquid. I emptied out my entire setup of contaminated antifreeze+water and put in about 30% Mr. Clean, 70% water solution.
Here are some dramatic pictures:

What it looked like originally.

It's pretty amazing to see all those bacteria bits peel off the tube and go shooting down the circuit. Then the white residue that coated by tubing starts to peel too!
This is amazing stuff. Easy cleaning and didn't require me to take apart my whole system (just needed to empty the rez and put in the cleanser).
