PrimoChillWater Cooling Cleaning Prep Kit - New System

I had a bunch of discolored and stain coolant linesIncluding my water block for my 3090Ran the cleaner through and then the prepThis stuff is amazingI had new lines to install and it did such a good job that it looks like the first day that I built it

The media could not be loaded. The blue color means how dirty the radiator was. After an hour, The story changed, Clear as water, I did it twice, After an hour, Everything clean as mentioned, NOTE! Step 3 didn't work System started to get oily, Don't use step 3, You really don't need it in your systemI definitely recommend it.

The kit was super helpful for getting my loop ready for coolant. The only thing that was confusing was the lack of instruction on which product to use after which. The pre loop powder that is only for radiators made sense, but then the next two I wasn't 100% on which to use first so I just went in order that they came packed in.There was also no real guidance online either, so maybe I'm just to much of a simpleton to figure it out but it seems to have helped with my new pc.

Came in well packaged

Easy cleaning solution that helped clean out my system. Radiator and cpu block were pretty clean, but I figure the little crap this removed would have bothered me if I had seen it floating around in my white coolant.

The System Reboot is missing from the box; presumably stolen to be sold separately. Instead, I have a second small bottle of pre-treat. Worthless.

The rad cleaner didn't clean any better than good ole vinegar. I had two identical rads made by the same company at the same time. Used vinegar in one and Rad Clean in another and solutions after cleaning/soaking both came out almost the exact same shade of blue.The primo Prep is what really worries me though. If anyone ever made a "super saturated solution" in school. You put more salt into a volume of water than it can handle. Eventually the crystals reform.I shook the hell out of both "Primo" and "Sys" prep bottles before adding them to the correct volume of distilled water, then I shook that as well before adding it to the loop. I dint notice anything with the sysprep bottle, and its 12 hour run and flush.However the primoprep you run for 3 days. During those 3 days I happened to pick up the bottle to recycle when I heard something rattle around. It was a clear crystal like disk made of something that precipitated out of solution while in the bottle.My first thought was to add some water and dissolve it and add it to the loop as I figured the 34oz of solution running in the loop couldn't be full strength. But trying to get the crystal to redissolve was a nightmare and that caused even more concern. Are there little pieces of crystal flowing around my loop now that could get stuck or partially block otherwise good coolant flow??Whiskey Tango Foxtrot ...Finally Primo chill mentions to thoroughly rinse this out as this combined with the inhibitors in your coolant would over saturate your loop. So if its just inhibitors, the same ones in your coolant why spend any money on this at all??I'll definitely go back to mayhem prep products on my next build, I'd give this a pass.

You can NOT clean your loop with this! The package does not include System Reboot loop cleaner, which is both shown in the product photo and on the packaging box, instead it has a SysPrep bottle that’s not shown in the photo but also listed on the packaging. But the sysprep seems to do exactly what “primo prep” bottle does, so no cleaning stuff but two prep stuff… Very confusing product description.
