Does anyone have any knowledge of or experience with cooling system rust removal products like Evapo-rust cooling system cleaner or ER cooling system cleaner by Orison Marketing? I have a 90 twin turbo with bad recurring cooling system rust problems and I was wondering if they are safe for use in turbo charged engines? , or are they just another snake oil type of thing? Any help would be appreciated.
