Oil-Off is a specially formulated industrial strength degreaser that breaks down oil and grease on contact. It is biodegradable and garden friendly. Oil-Off is super concentrated so that it may be diluted with water 1:1, (one part Oil-Off to one part water) for less serious stains. It is multi-purpose and can be used on paving stones, concrete, asphalt, tires and rims, car engines and barbecues.
