Radiator Cleaning/Flushing

[Obrej]

So i've ordered everything for my new loop and i am wondering how should i clean out my new radiator as i've seen lots of recommendations online to do so. Most recommend using distilled water but where i live we can't get distilled water from supermarkets and its to expensive to order online. Would using hot tap water be ok? Does anyone have any other recommendations?
Thanks

You shouldn't use tap water. And also is there really no distilled water available in Wales? Come on ôo

Edit: I found a tutorial in german on how to make your own distilled water. I guess there should be also a tutorial available in english somewhere. Maybe you can find one on google.

But I don't know if this is safe.

Hot tap water is better than nothing. But make sure you don't fill your loop with it. You should rinse them with hot water twice before putting the loop together.
