Okay, time to debunk some of the common ones:

H2O2 (Hydrogen Peroxide): corrodes the fsck out of your blocks, decent biocide

Bleach: corrodes the fsck out of your blocks, very good biocide

Methanol: neurotoxin that WILL slowly seep through your tubing ... do you want to die? Only really good for sub-zero applications ... very good biocide, but lowers efficiency of water loop

Antifreeze: lowers efficiency of water loop, good anticorrosive, decent biocide

Water Wetter: helloooooo white deposits, very good anticorrosive, mediocre biocide, can increase efficiency slightly

Hyperlube: negligible deposits, very good anticorrosive, mediocre biocide, can increase efficiency slightly

Isopropanol: you need ALOT to keep your system bug-free (I used 25% of commercial solution, or about 5% total solution and it did NOT work) and it lowers loop efficiency ... not an anticorrosive ... not recommended

Non Chlorine non bromine sanitizer: not an anticorrosive, VERY good biocide, can cause slight hose filming, lowers loop efficiency

*sol (75% Pine Sol 25% Lysol): cleans hose deposits, kills bugs, raises your grandmother from the grave, organizes your socks, VERY bad for efficiency

You guys be the judge ... my fav glycol mix is the red stuff. Mixed with hyperlube it takes on this diluted blood red/orange look and is pretty wicked.

edit: to do a *sol flush you just need to empty the fluid from your loop and add the above proportioned mixture to your system. The filthier it is, the higher concentration you need to use, though I'd add a bit of water just to thin it a bit if you don't have a burly pump. Drain, flush, and refill with your coolant of choice for a nice clean loop.

I should sell the stuff, hehe ... then I'd be almost as parasitic as some of the mainstream watercooling companies out there! ... On second thought, I'm not that evil ....
