Limescale like substance?

[Woofly94]

I took my loop out few months back and I forgot to flush it out, I want to put it back in now but I've noticed limestone like build up on the tubing and waterblock, I've replaced the tubes but there is still this build up inside the waterblock and possibly the radiator too, I was wondering if it's still suitable to use and wouldn't cause an issue further down the line? I've tried running the loop with vinegar in for few hours it sort of worked, but didn't clear out most of the build up, is there anything that's better than vinegar that will clean the loop? If it's any help, I've only used Mayhems Pastel in the loop. Thanks

Mayhems Blitz cleaning should help. It can be found here.

Make sure you follow the timings and instructions as you need to let the chemicals work.

just take waterblocks appart and clean them with a toothbrush.

For proper cleaning you need to take apart the loop and all the blocks to ensure they are scrubbed clean. If there is any kind of nickel in your loop it's not recommended to use nickel as it can affect the plating.

Thats likely plastecizer buildup. You only get limescale from water that has come from a chalk/limestone aquifer.

Distilled water and premixes are 'clean' so no limescale.

Hard to say without a picture, but probably just left over caked/dried out "nano particles" from the Pastel. Would need to crack open and give it a good scrubbing to take it out. Shouldn't cause any additional issues unless you change the coolant to something vastly different, I think,
