Blue crystals... deposited silicates.
Avoidable by changing coolant at least every two years.
Depends how much there is... it can be removed by running a dilute acid solution, some say citric acid, some say oxalic acid.
Never tried it myself.
If there is a good radiator place near you, you might go and ask them what they use for cleaning.
