68 hemi aluminum waterpump housing.

After a ransak of all the little lady's cleaning stash I didn't turn up any of the products suggested above. Looks like a trip to the store is in order.
I did find a product called super iron out stain remover and can report here for everyone's
benefit to leave it under the sink.
Didn't touch the rust and had a horrible vapor that I can still taste when I mixed it with water for a parts bath. To be continued another day.
