I'm waiting for my WC parts to arrive this week and the only part I'm not completely clear on is the proper way to clean the radiator (NexXxoS UT60 480mm) so I just wanted to hear what you guys prefer doing.
 
Fill, shake, empty repeat. That's how I do it mate. I no some people connect it up to a tap, and flush it for a while, others add a small amount of vinegar to the water. I no Mayhems have just released a Blitz cleaning kit that is meant to be really good.
 
I just boiled a pot of distilled water, let it cool down for a bit, and fill / shake / empty / repeat. But be sure to wear oven mitts if you go that route.
 
I tend to put warm clear vinegar in mine, give it a good shake, let it settle a bit and shake some more. You wouldn't believe the crap that comes out of some rads.

That twice, then dionized water flush twice until no more particles/colour change in the water then seal them up ready to go
 
Do One nede to flush the res and blocks as well?
I've never flushed a block or res. The reason for flushing rads is to get rid of flux/solder left over when the rad was assembled. Blocks and reservoirs obviously aren't made the same way a rad is, so there usually isn't any crap in them.

Thank you.
