Choosing rubber for your professional window squeegees
What are the different types of rubber for window squeegees?
Unger squeegee rubber
The Unger brand is renowned for its high-quality products for window cleaning professionals. Their rubbers come in several variants, each offering specific properties:
Unger Green Label Rubber : A soft and flexible natural rubber, ideal for gentle cleaning.
Unger Power Green Rubber : A more resistant version, with medium hardness, perfect for dirtier glass surfaces.
Unger Power Blue Rubber : A harder rubber, designed for intensive use and very dirty windows.
Rubber window squeegee Ettore
Ettore, another major player in the market, also offers a range of professional quality rubbers:
Ettore Hard Rubber : A very resistant rubber, ideal for very dirty windows or extreme weather conditions.
Ettore Soft Rubber : A softer rubber, perfect for gentle cleaning of delicate surfaces.
Ettore Mixed Rubber : A compromise between hardness and flexibility, offering effective cleaning without the risk of scratching the windows.
The hardness of the window squeegee rubber The hardness of the rubber, measured according to the Shore scale, is a determining factor. A harder rubber (Shore A 60-90) will be more resistant and effective on very dirty windows, while a softer rubber (Shore A 40-60) will be softer and suitable for delicate surfaces.
Rubber Width
The width of the rubber should match the size of your squeegee. The most common sizes are 25cm, 35cm, 45cm, but sizes up to 105cm may be available for large glazed areas.
Another possibility is to take 105 cm which you can then cut.
Environmental conditions, such as temperature and humidity, can influence the choice of rubber. Harder rubber will be better for cold climates, while softer rubber will be better suited to hot, humid environments.
The configuration of the surfaces to be cleaned can also guide your choice. To reach windows at height or in tight spaces, a thinner and flexible rubber will be more practical.
Choosing the Right Rubber Hardness
The hardness of the rubber is an important point to take into account when purchasing a professional squeegee or renewing the rubber. There are several hardnesses to adapt to climatic and surface conditions.
Hard Rubber (Shore A 60-90): Ideal for heavily soiled windows, outdoor environments and cold temperatures. Offers a deep clean but can be more abrasive.
Soft Rubber (Shore A 40-60): Perfect for delicate surfaces, lightly soiled windows and hot, humid environments. Cleans gently without risking scratching.
Mixed Rubber (Shore A 50-70): A compromise offering a good balance between hardness and flexibility, suitable for the majority of window cleaning situations.
