Yellowish residue in reservoir - Page 2

post #11 of 17
10% distilled white vinegar solution (or 9 cups boiling water mixed with 1 cup distilled white vinegar) will loosen the most flux from a radiator. The best method would be to fill the radiator with said solution and cap it, then while wearing gloves so you don't burn your hands, give it a good shake for a minute, then let it sit for another 3 or 4 minutes and drain. Flush with hot tap and then final rinse with distilled. The water will be bluish (vinegar reacts with copper) and full of sand like flux. I did it...I was surprised actually.

Change of events. Not sure if it's still flux, but it most certainly could be. My computer has been put together for ~2 months now so I don't really want to take it apart just to get the gunk out of there.

However, I put on a rubber glove and stuck that into the reservoir. The yellowish residue is like glue...it was sticking to the side of the reservoir pretty tough. I could pull it up but it acted just as if glue would: rolling up the side of the reservoir until I rolled it out. I left some of it in there as it was kind of a pain trying to get it out, and it leaves a nice "gluey" streak up the side.

I figure if it's stuck to the side of the reservoir, I guess it's not doing any harm?

Wouldn't you rather clean it out? If it's flowing in your system it could be getting in your blocks, pump and tubes. I'm sure having that stuff in your blocks would hinder their performance.

I would love to clean it out, but cleaning it out means draining the loop, detaching the reservoir, cleaning it, putting it back together, etc...

EDIT: Honestly, I'll probably do it the next time I clean it out. I didn't expect it this time, so next time I will. Most likely when I go to a LAN. Just an excuse to take it apart and stuff. I think it should be fine for another few months? I'll keep an eye on it.

If you have a pic, I like to see it.

Does your yellowish residue in reservior look like something like this:

Sorry to say no, it doesn't look like that. Mine is definitely more yellow than orange.

To be honest, mine looks like someone smeared some of that sealant you would use with a caulking gun.

Could still use some help if anyones willing!

I tried scraping some of it off with a screwdriver today and that wouldn't be hard except it loves to stick to the reservoir.

It kind of looks like mozarella cheese when I pull it off but it looks like sealant when it's on. It started forming right at the water line so I don't know.
