Mop up any excess oil with rags. Cover the area with oil absorbent talc. Leave it on the stain for a day and then sweep up and wash off. Apply an oil remover product that will not harm the pavers follow the directions when using all chemicals. It may be easier and less time consuming just to change the stained pavers if they are available, if your pavers were installed by Basics Landscaping we are trained to leave a few extra pavers behind a shed. If you do not have the pavers please contact the office and we will see if we can help you match the paver.
