Default Re: Evaporust and radiators

I've used pure white vinegar straight from the jug. It's very cheap and I left it in for a few weeks while driving the car. It will make the water pump leak when it removes the grease, then you have a very rusty mess getting all over the engine.

It worked, but Evaporust would be a better way to go I think.
