You can't "clean" a radiator. If it has internal clogging, replacing the radiator is the only way to resolve it.

Also make sure the cooling fan is coming on. It should be on whenever the AC is on.

I already advised you that the radiator can't be cleaned but you want to debate that so I have nothing else to offer.

You may have already done serious internal damage to the head or head gasket caused by previous overheating. You should get it chemical tested for exhaust gases in the coolant.
