I like evaporust but it sure has it´s shortcomings...
As already stated it hates anything petroleum based so you need to run some detergent first and make sure all grease and oil is out.
Next is air kills it to so keep it in closed containers...open contaier soaking stuff and the contact with air shortens its lifespan.
I usually just pour it straight in not using thermocure just the regular stuff run the engine a bit now and then letting it work for a day.
Then drain radiatorhoses off and flush it with the biggest waterhose available.
From what i found extended periods of soaking without flushing or brushing doesn´t do much so atleast run the engine daily trying to loosen rust scale and other stuff.
Best is to flush it out and do another run with evaporust again.
