Can someone tell me the process, and what equipment I need to do this, the school system is wanting an estimate
There’s a number of ways to go about it. You’ll need a smaller PW…no more than 3-3.5gpm and a turbo nozzle. …too much water in an enclosed space is tough to work with. Hot water is a must. You’ll need a really good degreaser or caustic. Some companies cover all the equipment with a thick plastic and use wood shims to secure it under the hoods. Others will just pull all the equipment out. If you do the entire job you’ll to go up on the roof and clean downwards as well.
Ok ,great already have pressure washer,how do you video them
You really need to go work with someone who does hoods. This is not something to just jump into.
I spent 30 years in restaurants. I have seen guys been completely wiped out being sued when a restaurant burns down and the fire Marshall determines the hoods were not cleaned properly allowing for excessive grease buildup that escalated the fire. You will also need to have specific commercial insurance coverage for this as well (not just normal commercial insurance but specific to exhaust hood cleaning - when I got my coverage they asked me 3-4 times if I would be doing hoods and specifically stated that hood cleaning would NOT be covered in my policy).
I had one restaurant that had 2 90 degree angles in the hood vents. Some of our restaurants had hinged fans others did not (this makes a huge difference for the guy on the roof).
Most commonly, guys will put thick plastic around the hood using shims or clamps and have it funnel into a trash can. When the can gets full, they dump. I have never had a guy move all our equipment out of the kitchen. No way…Unhook gas and electrical, move, clean and then reconnect. Never, ever not even once in 30 years I have seen or heard of that.
I considered it, but really, it is not appealing. Almost all late night, over night or early morning work. The pay is also not great or at least from the invoices I paid - $350-$400 to work overnight, for 3-4 hours per job dealing with a greasy nasty mess. No thanks…

I do a hood job once a month for the past 8 years. I got lucky in that the the manager has about 6 employees stay and pull all the equipment which involves unhooking gas lines. They pull all the equipment off the line and scrub the sides/backs while I hit their hoods and stainless wall. They have a hood company that comes in quarterly that cleans from roof down. I’ve done the funneling into a trash can thing and it’s not fun. Mostly prep work. As mentioned I wouldn’t jump into it as you’ll probably jack something up. I just do the underneath side, dry, and put Medallion stainless cleaner and it looks great but I don’t vet on the roof…not this guy. Employees put all equipment back so I’m not liable. I’m there an hour.
