As always, when using an industrial strength tar remover such as Tar Release™, please take care and use the proper safety equipment and caution. Maximize your safety and the safety of others by wearing gloves and eye protection, and working in a well-ventilated area.
To use as an engine degreaser, spray Tar Release™ on the surface of the engine. Allow adequate time for the product to work and loosen up the dirt, grease, etc. Times will vary depending on the thickness of the grime. The thicker the grime, the longer Tar Release™ will take. For very tough degreasing jobs consider more than one application. After adequate time, rinse the grime away. For best results use a power washer. Power washers with hot water work better than ones that don’t have hot water capability.
For lighter jobs, Tar Release™ can be prediluted with water and applied to the surface or it can be used with a power washer as the detergent. After cleaning, rinse all surfaces adequately as to not leave any residue.
