The art of window cleaning in Paris
Paris is the City of Light, and that light enters your interiors through your windows. From the grand Haussmann bay windows of Boulevard Saint-Germain to the industrial glass partitions of Le Marais, through the fully glazed facades of contemporary buildings in Boulogne-Billancourt, each type of glazing requires specific expertise and techniques to achieve perfect transparency.
At Lemon Soap, window cleaning is not an ordinary household task. It is a profession in its own right, performed by specialized technicians who master the most advanced professional techniques. Our goal is simple yet ambitious: absolute clarity, without the slightest streak, without the slightest haze, as if the glass had simply disappeared.
Haussmann windows: a glass heritage
Haussmann windows are iconic in the Parisian architectural landscape. These large double-casement windows, often fitted with glazing bars and period hardware, present unique cleaning challenges. The multiplicity of panes, painted wood moldings, brass or wrought-iron handles: each element requires specific attention.
Our technicians begin by dusting the frames and glazing bars with a soft brush, then clean each pane individually with pure deionized water. Brass hardware and handles are polished with an appropriate product. The exterior of the windows, often difficult to access in Haussmann buildings, is treated with professional telescopic tools or, for upper floors, by technicians certified for working at height.
The pure deionized water technique
The revolution in professional window cleaning rests on a simple yet remarkably effective technology: pure deionized water. Filtered by reverse osmosis, this water is stripped of all minerals and impurities. When it dries on glass, it leaves absolutely no residue, unlike tap water which contains limestone and mineral salts responsible for white streaks.
This technique is combined with the use of professional soft rubber squeegees by Unger or Ettore, recognized as the world references in the industry. The squeegee motion, executed in reverse S or fan patterns depending on the window size, removes water and dirt in a single pass, guaranteeing a perfect result from the first gesture.
- Water filtered by reverse osmosis to 0 ppm residue
- Professional soft rubber squeegees
- Single-pass wetting and squeegeeing technique
- Edge finishing with lint-free microfiber
- Natural drying without streaks or haze
The light of Paris deserves to enter your interior without any filter. Perfectly cleaned windows transform the quality of life of an entire space.
Mirrors, shower enclosures and glass surfaces
Interior and decorative mirrors
Mirrors hold a central place in the decoration of luxury Parisian interiors. Large gold-leaf gilded mirrors in Haussmann salons, frameless contemporary mirrors in modern lofts, antique Venetian mirrors in exceptional bedrooms: each type of mirror requires treatment adapted to its frame, coating and era.
For antique gilded mirrors, we clean the reflective surface without ever touching the gilded frame, as moisture and chemicals can damage the gilding. For frameless mirrors, we treat the edges with particular care to prevent moisture infiltration that could oxidize the silvering. For Venetian mirrors, only a slightly dampened microfiber cloth is used, without any chemical product.
Shower enclosures and glass partitions
Extra-clear glass shower enclosures in luxury bathrooms are particularly exposed to limescale deposits. In Paris, the water is naturally hard, which accelerates the formation of a whitish film on glass if maintenance is not regular. Our professional anti-limescale treatment removes existing deposits and forms an invisible barrier that considerably slows limescale reformation.
Interior glass partitions, very popular in lofts and renovated apartments, require cleaning on both sides. Our protocol includes safe access to upper sections via stepladder or platform, and methodical cleaning panel by panel to guarantee a uniform result across the entire structure.
Crystal chandeliers and exceptional light fixtures
Cleaning crystal chandeliers is one of our most delicate specialties. These masterpieces of craftsmanship, which can feature hundreds of pendants and arms, require partial disassembly, piece-by-piece cleaning and meticulous reassembly. Our technicians are trained to work on major crystal brands: Baccarat, Lalique, Swarovski, Murano.
Each pendant is individually cleaned in a gentle solution bath, then dried and polished by hand with a microfiber cloth. The arms and metal structure are treated with a product adapted to the material, whether gilded bronze, patinated brass or polished chrome. The result is spectacular: the chandelier regains its full brilliance and projects light of incomparable purity.

A crystal chandelier is not cleaned, it is restored. Each pendant regains its original brilliance, and with it, all the magic of light awakens.
Glass facades and working at height
For contemporary buildings with fully glazed facades, we deploy teams specialized in working at height. Our technicians hold the necessary certifications and use certified safety equipment: harnesses, ropes, cradles and anchoring systems compliant with current regulations. Each intervention is subject to a risk prevention plan validated in advance.
For private residences in high-rise buildings, we coordinate our interventions with the building management and occupants to guarantee safe access to exterior facades. Cleaning is carried out with the same quality standards as indoors: pure water, professional squeegees, streak-free finish.
