PrimoChillWater Cooling Cleaning Prep Kit - New System

So far I've used the Rad Clean on 7 radiators from old to new. Originally, all of them were already flushed with distilled water or vinegar solution, until no particles came out. But after peeking thru the G1/4 port, I did not like how the end-tanks were still filthy on some of the radiators.Decided to give Rad Clean a shot. I followed the instructions, Rad that was once assumed clean, had all sorts of particles came out, Rad Clean was able to dislodge them from the interior surface. If there's any old coolant gunk, oxidation on copper/brass surface of the inside of the radiators, now they would be have fresh, bare surface.There are some who runs a pump & filter loop to clean their rads. You can run the rad clean solution in that setup too. But you haven't invested in such setup or even an ultrasonic cleaner. I am certain this is one of the top best ways to clean in less time.Highly recommended! Thanks for stocking this item & will definitely purchase more in the future.

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 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.

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.

Very disappointing. First, they won't tell you what's in the products - what kinds of toxic chemicals are these? Second, absolute confusion about which product gets used first - no instructions provided. Third, how many times exactly must I flush my loop before what they've added to it is removed? Because ever time I do, there's some kind of powdery residue left inside my tubing and water blocks. Fourth, if this is supposed to dissolve or remove or flush or whatever in order to protect my water blocks, why did I have to tear apart my water blocks after each iteration to physically clear whatever crap was stuck into their fins after each "flush"? There was literally nothing in my loops... when done with each step, there was crap in my fins. Will never buy this again and think nobody else should either.

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 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.
