If your locks are rusty, rub them with household oil. Then remove the oil and dry the lock properly. Add metal primer and spray or brush on a durable enamel topcoat. Let it dry. Use household oil to lubricate the moving parts.
Pour ½ clear household ammonia into a pot to produce a new antique finish. After that, put the cleaned brass lock and cover the dish with plastic wrap.
