Pressure Washing Cleaning Middleby Marshall

We called a company to clean our oven as it has been neglected for many months. The company suggested - to save time and money - it so pressure wash the oven without dissembling! Has anyone done that before? Is it safe. Input please.

Don’t do that. They aren’t hard to disassemble. Remove the deck, side panels, then the fingers. Remember where they go and any block off plates.
