GRAND BLAST is a heavy duty degreaser that is dilutable at different rates to adjust its power for different types of cleaning and degreasing. GRAND BLAST is intended to be used by detailers to clean under the hood and in similar heavy grease and oil deposit areas. GRAND BLAST is so powerful that it is also used by repair mechanics that want to clean the engine or axle area of grease and dirt before making repairs. .You will not find a more powerful degreaser that is still safe to use at a dilution of 4:1 all the way to 10:1. This degreaser would be extremely helpful if you have to clean up sticky and gunky parts like carburetors.
