Dealership cleaning needs experienced cleaners
Unlike normal office cleaning, dealerships require a lot more window cleaning and usually have high shine showroom floors that need an experienced cleaner to look ready for customers.
Large facilities cleaned every night require high level cleaning experience
Few cleaning companies are mentally prepared to clean in the middle of the night every night of the week. Even fewer are capable of large facilities, and even fewer still can handle the unique requirements of a dealership.
That’s why experience and equipment are the bare minimum
Larger dealerships should require that any cleaning company they choose already have dealership cleaning experience, and come in with auto scrubbers or floor machines. Otherwise you are paying for cleaners to spend longer than they need to using a mop and bucket which usually isn’t as good a machine.
