You flush it through for a while to flow any crap out and it ends up in the bucket, then you throw that away, and rinse the loop with some fresh clean distilled,
I use about 10L of it and walk away for about four hours, rinse with a fresh 5L then drain and refill,
My own loops a bit different to most though and can't be removed from the Pc, I have to flush it in situ,
old photo but I still flush it the same these days, and my radbox gets looped separately at the same time

If the rad has been used previously then the blue was just the reaction between the bleach and vinegar, put small amounts in a cup to replicate the effect, I'm going to when I gt home in the morning hehe
