Cleaning a radiator

I,ve got a aluminum bike radiator which l,m trying to clean up but being 24 years old it has a lot of rust and crap inside the matrix, l,ve flushed out what l can with water but there is still alot of thick rusty crap on the inside.

Any ideas of what l can use that powerful enough to clear most of the crap out, found a thread on ADV rider saying to use battery acid (Sulfuric acid) but from memory that reacts with aluminum to produce hydrogen gas!

Caustic Soda? Like what they do with exhausts, I don't know if it would be too harsh on it.

Wikipedia says keep away from aluminum, so must eat through the stuff

Caustic soda eats aluminium. thinking along the same lines though, some other less powerful drain cleaner?
