Few drops of WW turns coolant BRIGHT white! WTF?

redleader · 10-06-2002, 05:37 PM

I've been running straight water for the last two months. Last night I added some alcohol (isopropal) and then this morning a few drops of WW. The reason is I hate WW, so I'm running alcohol as a biocide. Works great. When I popped the top of my radiator I heard a satifing pop sound indicateing that my system is air tight.

Anyway I added a tiny amount of WW. I'm talking 1/10 the recommend amount. The instant it hit the water the stuff turned brillant white. Anyone ever do titrations and add very weak acid to a strong base w/ indicator? It was like that, the red just vanished on contact.

Then the white spread out from the res and within 10 seconds my entire system was white.

Now I've run alcohol and WW before with no trouble. I know thats not the problem. I don't, however, have any idea what happened. Has anyone else seen this before?

Wish you could've gotten that on video tape

Its been 8 or so hours and its just a pale white now. How odd.

What else does that?, Jeyes fluid/bleach does does'nt it?. Are you sure the H20 did'nt have anything else but Isopropal Alchohol in it before the WW?. I've never used WW so I don't know it's peculiaralitys, but it can stain some tube white can't it?.

Actually all reports of WW deposits were talking about either pink or black residues. Not white.
Some component in the WW reacted with whatever was present in his system besides isopropyl alcohol, maybe calcium from water (was tap water, right ?). I'm not a chemist, so i cannot say more than: "wow. amazing."

I could be wrong but I believe WW also posseses biocide properties. Was the alcohol necessary?

My system holds easily twice what the average inline system does and I used a few drops worth of WW. I doubt that would work too well as biocide.

It was distilled water.

I used a new heatercore and tygon tube. Both were flushed extensively. The only thing I can think of was the "Marine Goop" silicon based sealant I used. Perhaps some of it dissolved something into the water that reacted with the WW.

Whatever it was it was, the stuff seems to be leaving the water in the form of a white percipitate that clings to the tygon very well. If enough settles I'll try and filter it out to see what it was. I'm just happy that my coolant stopped looking like Milk without too much trouble (so far).

Percipitate =gunge, yes/no?

.

I would'nt trust it, imagine the inside of the rad!. I'd have to strip and flush it if it were me :shrug: . I'd refill with just H20 and WW too, if mixed to the right amount it does actually fufil it's 'secondary' role as a biocide does'nt it?. Why do you hate WW so much?, your system is closed yes?...

Hmmm, i thought WW:s recommended dosation was 1/32.... Btw, when i used 1/32 instead of something like 1/10 i got about 5 degrees of my CPU.

i would still go for some leftover treatment chemical in the heatercore that you were unable to get out with flushing.
