Dirty water in my radiator, what to do? Options

[Ugglan]

Hi,
I need some help with my radiator, the water is pretty dirty. I think I might go to my parents tomorrow and try to flush the system but have anyone else had this problem?

The brown stuf is not hard, rather like soft mud or wet sand. No samll stones or anything.
Any ideas of what it is and why it is there and what to do?

Wow, thats pretty bad. Yeah, you def need to flush it, I only wonder what the coolant passages look like. You can try to do it at home, with various radiator flush stuff from an auto store, but in your case, Id start calling around to shops and seeing how much a coolant flush is going to run (block and all)
