I'm almost done with my watercooling setup, and I'm going to expose the radiator to the cold Illinois winter temperatures. I'm going to use a mix of windshield de-icer because antifreeze is pretty nasty, and expensive (I'm using a 10 gallon fishtank as a reservoir). The problem is, de-icer doesn't have any corrosion inhibitors. I won't need much, because my system is completely copper and brass (with a bit of 15% silver brazing rod), but I don't want ANY corrosion. What else could I use to inhibit corrosion, and about how much of it would I need?

I know Napa sells a milky-white Anti-Rust thing. It contains all kinds of silicates and other stuff I wouldn't be too happy about putting in my system, but it's basically a bunch of corrosion protection without the ethylene glycol.

ehhh im finally back from the winter break so I can finally start posting again at OC forums YAY!!!!

If you go to any autostores or any place that sells auto antifreeze you should be able to find a corrosion inhibitor w/o EG lik johnan851 mentioned... I guess the mixing ratio depends on what kindda metal is in your loop
