Hemi Joel Posted March 11, 2015 Share Posted March 11, 2015 I was thinking about using Evapo Rust to clean out the water jackets in my cylinder block. But it is quite costly, and takes over a week to get. Then I remembered how well Iron Out works to clean the rusty toilet tank. I am quite certain that it would clean the water jackets well, but would it cause any damage? Is it is acidic? the engine will be completely torn down, so I could do the derusting while it is all together then finish up after it is apart.thanks, Joel Link to comment Share on other sites More sharing options...
