Hi All

I have a radiator which has a load of gung in it. I have taken it off and wanted to clean it before putting it back into operation. What's the best thing to flush it all out with. Assume a hose will get most out but what will clean the rest out?

Thanks

Lee.


Take it outside, mount upside down a in workmate, tilting
down at one end and blast it with the hose pipe until it
runs clean.

You could then stick some bungs in the exi hole and fill up
with a weak acid of some sort to loosen any remaining
crud.

Then dry it with a wet-n-dry bvac in blow mode. After a
few minutes the air being blown will be quite hot if it
is an older powerful motor variant.
