Soaking in a stagnant bath will remove some of your build up...

However, it is when you circulate a warm solution through the
inside of the device you need cleaned that you will have the
best performance -- the circulation of the cleaning solution
provides a scouring action...

How do you circulate your beer and water through this
heat exchanger ?

Probably worth investing in a small pump which you can
get with hose threads on it for cleaning your set up...
