Yeah I do it quite a bit, have you cleaned kitchen equipment before, it can be a pain, even down to using razor scrapers to get some of the build up carbon off. I use Sodium Hydroxide with a thickening agent to make it cling, if you don’t want to do that a spray on oven cleaner will work also, it is more expensive though.
Start with the equipment, scrape off any heavy grease, and apply the cleaner. Move the equipment if possible to get to the floor underneath, scrape up any heavy grease from the floor and throw down some degreaser. Let all of this work while you go tape off or cover anything electrical. Make sure that the cleaner you have soaking on the equipment and the floor does not dry, reapply if this starts to occur.
You may need to also use a degreaser on the walls. They tend to get a grease build up also. Don’t use the caustics, use something more user friendly, and of course if they are painted, don’t use degreaser at all, the best I would do for a painted wall is 409 wipe down. If it is a tile wall I would also use less pressure washer, 1500 @ 2.1 is my weapon of choice, simply as a precaution for the electric and not wanting to blast out any loose tiles, which you will want to look for before cleaning.
Clean the wall starting at the wall farthest away from the hood, this allows the equipment to soak longer, when I get to the hood I do the equipment, don’t be surprised if you have to reapply the cleaner on the tougher area’s. I also would have at some point have spread some cleaner down on entire floor, allowing it to soak, while I am working on something else. (Caution: this will make the floor slippery, a tradeoff I make because it can help tremendously with removing the dirt from the grout) don’t let the cleaner on the floor dry.
Once the equipment and walls are done, I would use a surface cleaner on the floors, it can be done with a wand, but you may have to go over every grout line, not fun. I may also use the wand for a final rinse of the floor. The surface cleaner will loosen the dirt but leave it in place, I either use the wand to push it towards a drain or towards a common area where it can be vacuumed up.
Obviously this is a sample of what we do. You will have to adapt it to your situation. Before you give a bid, find out if they can move most of the stuff out of the kitchen before you start, or if you are not cleaning the tables you may be able to move most of the stuff to the tables and cover them with plastic. Most of my customers want the underside of the table and legs cleaned for health inspection purposes.
Oh the answer to your question is yes
