Experiment Cu: vinegar, vinegar + salt, solvent

[Cyprio]

I use X300 Universal Cleanser, it’s used buy heating engineers to Flushes out flux and installation debris from new indirect central heating systems.

I spoke with the tech department at Sentinel and they told me it wouldn’t harm my watercooling parts.

So I used it to clean my PA120.3 & BIP before installing, and it did a great job.

I’m just about to strip my system down to do a full clean, so I’ll use it again.

Do you leave it to soak or flush it through? It's pretty cheap so if it does a good job without harming any hardware i might give it a go as well.

Edit: just read the .pdf and it has instructions!

Vinegar is no longer used to clean anything,

According to --> MaxxxRacer's Water Cooling Guide: The basics An Introduction to Watercooling your Computer <--

1. Flush the radiator with distilled water. I suggest getting 2-3 2.5gallon jugs and just start pouring about 2.5-3gallons of distilled through the rad.
2. Pour Distilled or De-Ionized water into radiator. - Pour until full, drain and repeat. Shaking the radiator when it is half full of water will help. Repeat this 3-5 times.
3. Following the same procedure as in step 2, repeat with vinegar.
4. Fill the radiator with vinegar, and let it sit for appx. 1 hour.
5.Flush the radiator, following the procedure of step 2. Repeat Step 3 as well.
6.Repeat Step 4.
7.Repeat Step 2.

I have updated the guide to limit the soaking of components in vinegar for no more than one hour. A tale-tale sign that vinegar is eating your copper components is a blue tinge to the vinegar, which is caused by copper ions being dissolved into the vinegar.

All you do is mix a small amount of Sentinal with some warm water, then fill the rad and leave it to soak for about 30 mins. I give the rad a few good shakes to help release the flux.

Then rinse the rad in the normal manner.

You can repeat the process more than once if you need to.

I have loads left and it will last you a good few times

I'm fairly certain that both of those are slightly outdated. Any rad that is RoHS compliant does not require vinegar for cleaning as the flux used is very different. Also. any non-RoHS rad that has already been cleaned does not need to have vinegar run through it again. Only boiling water is needed for both of these scenario's.
