Basically none of the 'Net suggestions for home brew aluminum cleaners really work for castings that have water stain/black spots damage.
Vinegar is no better than plain water.
A nylon brush may remove dirt and soft crud but has No effect on stains.
Cream of Tartar & Vinegar paste is a waste, save it for baking.
A brass brush is somewhat effective but changes the appearance to a soft polish without actually removing any but the lightest stains.
So this set of Dellorto's will be getting soda blasted.
I've done this before and it really cleans the aluminum but Still will not remove heavy stains.
Glass Bead blasting will take out stains but is too aggressive at close range and disappointing from a distance.
I will probably end up painting the major pieces for the best finish as Vapor/Dry Ice blasting is just not available to me.
