Removing stubborn oils can be a difficult task. Firstly it is important to determine what type of oil it is, as it will determine the best method for removal. For example, vegetable oils can usually be removed with a combination of hot water and soap. Grease and motor oils may require a heavier-duty cleaner such as degreaser or a solvent. When using harsh chemicals, make sure to wear protective gloves, a mask, and safety glasses. Once the oil has been treated, it may be necessary to rinse with hot water and soap or a steam cleaner. If the oil has left a persistent stain, a combination of a solvent and a scrubbing brush may be necessary.
