The aerosol gives the user the ability to get into hard to get to areas with the powerful pressurized spray which gives it a tremendous flush action. Also aerosols can be very convenient for the user that is continually mobile. We have successfully supplied this product to the Pennsylvania Turnpike Department of Transportation as well as other industrial users. In the turnpike's case they are using it to remove tar deposits on vehicles and concrete surfaces. Obviously this product is meant to be used for heavy duty degreasing applications only.
