Ok, so I used this guide back in the day (in early 2006) when vinegar was still being used and used in long periods of time in a radiator and water blocks.

I just upgraded my system and am looking to install a D-Tek Fuzion and Swiftech MCW-60.

How do I go about cleaning the blocks? Do I use vinegar as stated or will alcohol be better?

I know about the vinegar eating the solder (from rereading the guide) but I wasn't sure if this was a safe thing to do with the water blocks still or not. And before I go and ruin them...

Thanks!
