In the past alkalis have been obtained from burnt wood, burnt seaweed and stale urine, but they are now may made on a huge bulk scale from industrial processes e. Acids can be used to clean corroded metal surfaces because of their reactivity to metals and metal oxides to form soluble salts which can be washed away to leave a cleaner metal surface.
