House Shine is a cleaning service that professionalizes what people usually do amateurishly or on an ad-hoc basis. It started in Portugal and was built on a simple promise: a trained team arrives with its own equipment and cleans a home or business space to a fixed procedure, so the result is just as good every time. It differs from an ordinary cleaning company in that it doesn't rely on one skilled individual but on a system — the brand, the methodology, and quality control hold the standard even when the people on the team change.
