Advice on Complete system cleaning?

I am not sure if any of you remember but I had a build on here a little while ago, then I decided to double everything so I rebuilt the entire system again and when I finished I was waiting on my pt nuke to come in but I was in need of a computer so I put my distilled water in, and days later my father had a massive heart attack which came along with my family and I living in the ICU for almost a month in which I never put the pt nuke in.
Then after everything settled down at the hospital and my dad was released it was hectic in the house and I forgot to put the nuke in my system and I just remembered when I looked at my res and noticed a bunch of white film covering it, and when I opened up the box I noticed the same thing inside of all the tubes which tells me it is in the entire system.


So here is my question, I know everything that is in the system has that build up, so how do you recommend cleaning it out?
I was considering taking all of the tubing and radiators and putting them in boiling water for about 10 minutes and letting them soak in there.
for the gpu, two apogee blocks, and the chipset I have no idea what to do, so any advice on this issue is greatly appreciated.

ketchup + toothbrush for the blocks

pipe snake for the tubing

rag for the res

rad dance for the rad

water and a toothbrush for the pump.

never heard of ketchup method I will have to look into it. Thanks

check that out, hokie used it to clean his new pot, results were pretty good (visually at least)

The ketchup works because it's basically salt and citric acid with a little vinegar thrown in for good measure ...
