Re: Water based cleaner??
For water based cleaners, nothing beats Sodium Hydroxide (lye) and water, for cast iron parts, especially if it's heated!
You can't put aluminum in it but, you can not beat it for cast iron.
I think the formula is 1 1/2 lb to 5 gal water. Wear eye and skin protection, especially for larger parts and hose with water.
