The squeak of newly cleaned glass, the whoosh of a duster, and the melodic hum of a vacuum as it sucks dirt and debris from a carpet. This is the symphony of sounds that whirls around the crew from Shining Shield Cleaning Services. For more than 35 years, the business has dispatched its conductors of clean to homes and offices, where they orchestrate in-depth cleanings that can include whisking away trash, disinfecting kitchen counters, and mopping tile. The company’s bilingual staff is carefully screened by the business owners—one of whom is an active police officer—so clients can rest assured that their home and priceless antique-paste collection are being left in trustworthy hands.
