Answer Posted / rrr
oil does not cause steel to rust, its only makes easy to remove shuttering, oil acts as a protective layer to steel so exposed steel railings are coated with oil paint to protect, if oil is present in RCC steel please clean before concreting it acts as debonding agent between steel and concrete.
