Don't forget to put the heating on hot.

Thanks,
remember the radiator is my target.
After vinegar flush (not great) and alkaline (not great either) I was flushing with water and some whitish chips came out..but I believe there is much more still hiding.
My daughter came today from Europe and brought me 1kg of citric acid...
So I 'll first do the radiator separately. I'll start heat up 4l of water and put 300- 400g citric acid in, then pour it into the radiator and I'll see what happens.
I'll try to clean out the radiator, then I'll do a flush for the entire system, then I'll change the thermostat.
Best, Martin
