I received about 40 buckets for free some marked lead free all probably less than 20 years old. Almost all have some amount of scaling, discoloration, and or rust inside. Galvanized steel. Spent an hour or so washing some, wondering if it’s worth the effort. Should galvanized buckets with rusk or scaling not be used? I don’t like the look of bags or plastic buckets. The old buckets look nice. Does anyone make a plastic bag liner? What’s the next best option with similar aesthetic aluminum buckets?
