Hello everyone! I’ve got a cutomser wanting there food truck cleaned. I have a question as to what to use for these stains. Im assuming a degreaser? Its from the rooftop exhaust vent. And if ill need to scrub it or just be able to wash it away with some pressure. The rest of the truck isnt that dirty mostly dirt and dust so just planning on rinsing the rest since im unsure of using SH on this. Any help is greatly appreciated!
