Cleaning factories, generating plants and other industrial job sites is perhaps one of the most difficult jobs to define, because there is tremendous variety in the facilities a building service contractor is likely to encounter.
Industrial cleaning is dirty work; even maintaining offices in an industrial facility is demanding because dirt gets tracked in from factory floors. There are the challenges and safety risks of cleaning around heavy machinery, lubricants, paint, fiberglass and metal shavings.
Because industrial environments get dirty quickly, you have to clean up quickly.
Unlike dusting, you cant wait till the next day to clean up industrial dirt. The demand is immediate, and the margin of error is very small.
