Default How to clean a cooling system

I'll try to make this short. My 72 bird sat for a looong time and it had a lot of crud in the cooling system. A mechanic friend said they've used CLR to clean cooling systems. After using it and flushing it really good I've got what can be described as brown sludge sticking to the cap and who knows where. What can I use to clean up this mess?
