Which of the following cannot be used to rub the metal parts of farm tools before storage?
Answer Details
Water cannot be used to rub the metal parts of farm tools before storage as it can lead to rusting. Rusting is the process where metal surfaces react with water and air to form iron oxide, which is a type of rust. This can cause damage to the metal and reduce the effectiveness and durability of the tool. Therefore, it is important to dry the metal parts thoroughly after cleaning and use a protective coating such as grease, palm oil, petroleum jelly or spent engine oil to prevent rusting.
