We have an almost 70yr old cast iron bath. The surface below the water line is rough. I assume from the enamel wearing away. Its a pig to clean, its like cleaning sandpaper.....
Any ideas on how best to clean it? The surface 'holds' grime too which makes it harder. I often end up with clean run marks where the cleaner is sprayed.
I really need to get it resurfaced but don't have the s.
