I have my first commercial job for a restaurant this week.
I’ll be wrapping all the metal elements with plastic and tape first including the entire door. I’m concerned about the black paint possibly fading so I’m using a 5.25% concentration of SH that I plan to direct downstream inject at a 7:1 ratio from my 4gpm washer.
I’ll also be washing the sidewalk and using northstar heavy duty degreaser at a 1:20 ratio. Any tips for gum removal without hot water? I won’t be using any pressure except for the surface cleaner.
