Wondering what is the best method to clean out a cooler's core?
I have read about some "green stuff" which apparently is bad for the aluminum; as well as using kero or metho to slosh back and forth a few times, then rinse well with a hose.
Any actual insight from anyone who has done it?
I notice alot of people saying about taking it a radiator shop and having it pressure tested as well as tub cleaned. But I'm choosing to not spend the money if I can.
