What was your vc9 concentration and how long was it in there? Was the thermostat pulled and run on high idle for at least an hour? It may need a fairly strong concentration to break up hard water deposits.

I drove it for an hour,between 1500-3000 rpm.got it to 205*.put two quarts in it.the restore and vc9 did a good job of breaking it up,the problem is that the radiator keeps feeding it to my whole cooling system.after flushing the block and oil cooler I get nothing but clean water out of them.once I get to the radiator I get these flakes......all day long.called a shop and they won't clean it because of the plastic tanks.need to invent something that'll disolve it,instead of breaking it up.

The only instance I can think of when you are better off to use chemical cleaners vs. replacing is when you are dealing with a commercial boiler which cost $$$$$$ to replace.
The chemical cleaning costs can way exceed your cost of a new rad.
FYI, VC-9 is something like $60 a bottle.

How will this stuff react with an Iron block, with Aluminium components, bronze bearings, EPDM rubber hoses, coolant, and other cleaners?
I would say... too risky to find out.

My duty chemists have gone home for the day....
I think, for $225 and taxes, that is pretty cheap to not find out the possible reactions with a rusted block, possibly with hydrocarbon contaminants, casting sand (silicates), and a coating on the whole mess (from the coolant) that is suppose to protect it.
You are asking a question that needs a coolant chemist / engineer to answer.
------------------------
Just a note as to what hard water can do.... a place that I am at that have unusually hard water.
Brand new kettle ... 2 or 3 loads of water boiling in it results in about 1/2mm of scale on the pot.
The deposit builds to 2 to 3mm thick... chunks that can be broken and pulled out.

I was thinking that as well, but wouldn't want to be the guinea pig.

Well.....it doesn't react with rubber or plastic, it cleans iron, aluminum, brass, and copper, and it dissolves mineral scale. What else is in there IF you've already flushed the system with nothing but water? I can't think of anything that's not metal or rubber

CLR is mostly an acidic solution, similar to Restore Plus and vc9. I don't think it would be harmful, but I also don't think it would accomplish anything a strong solution of the other two wouldn't.

Not that the cooling system has direct contact with. Metal, plastic, and rubber, that's about it.
