After losing a belt, I have a lot of belt dust accumulation on my engine block and wish to clean. Is this the right product for the job? How is it applied and does it need to be washed down after use?
According to Spray Nine, this product will work for the job you are looking to do. They have advised that the surface must be cool before application. They also recommended to test the product out on a small area of the engine prior to full use. They say do NOT allow the product to dry, you must spray it on, then wash/rinse it off with a wet rag or towel.
