Just out of curiosity, has anyone tried using CLR to flush their engine out? or is there something in CLR that will damage internal components???
Ingredients: Water, Glycolic, Sulfamic, Citric Acids, Surfactants
Important: Do not use CLR on natural stone, marble, terrazzo, colored grout, painted or metallic glazed surfaces, plastic laminates, Formica, aluminum, copper, brass, steam irons, refinished tubs or any damaged or cracked surface. May etch old sinks, tubs and tiles.
hmmm guess it says not to be used on aluminum. oh well
i did hear of a product similar to this that said it was just as good, but not as harmful.. all i remember was that it was all Canadian...
