Thank you for the various replies.
I have now tried this and had very pleasing results. I used a handful of soda in a small cat litter tray (new), a 12v car battery and a battery charger topping it up. I cleaned the valve chest cover and a door hinge. The valve chest cover was so rusted that the breather holes were obstructed and the Austin legend was almost invisible. After a couple of hours, a scrub in hot water and a light brush to remove some stubborn paint, it is as good as new. The hinge was almost seized solid and was covered in payers of paint. Again, after a few hours, a scrub and a brush, it is clean, bare metal and hinges freely.
I shall avoid doing structural components as a precaution.
