An office or clinic sees daily traffic from employees and clients, and dirt builds up faster than in a private home. A recurring cleaning plan prevents the business from "starting from zero" with every cleaning.
Beyond appearance, recurring cleaning also contributes to hygiene, especially in kitchenette areas, restrooms, and shared work surfaces.
The right frequency depends on the number of employees and visitors: small businesses can often manage with a weekly plan, while larger offices or clinics tend to need a higher frequency.
