How do you remove hydraulic oil stains?

To remove hydraulic oil stains, start by absorbing excess oil with paper towels or rags. Then, apply a degreaser or a mixture of dish soap and warm water to the stained area, scrubbing gently with a brush or cloth. Rinse with clean water and repeat the process if necessary. For stubborn stains, using baking soda or cornstarch as a poultice can help lift the oil from surfaces.
