Description
- This invention relates to materials and products for the cleaning of glass, and is particularly concerned with the cleaning of windows.
- Various methods and materials have been used over the years for the cleaning of glass, and especially windows. These range from the use of special liquids to the use of special impregnated cloths and the use of chamois leather. However, none of these materials or products enables one always to obtain a perfectly clean surface without smears.
- It is an object of the present invention to provide a material and a product which enables one to clean glass surfaces, particularly windows, efficiently and with exceptionally good results in terms of clarity and lack of smearing.
- The present invention is based upon the use of a material comprising absorbent cellulosic fibres, preferably in block form.
- Preferably, the block comprises what is conventionally understood by the term "paper". However, other cellulose-based materials may be used if having sufficient absorbency.
- In accordance with the invention there is provided material in sheet or block form for the cleaning of windows, comprising absorbent cellulosic fibres and having at least one surface compatible with a window surface.
- A cleaning block or pad made of such material according to the invention is preferably made of compressed material. However, the cleaning product may comprise a compressed block portion or portions in combination with other portions having greater absorbency.
- The material may include one or more of a wide range of fibrous materials.
- The cleaning product of the present invention is preferably used after washing the glass with water containing a soap or detergent.
- Reference to the material having a surface or surfaces compatible with a window surface means that the material will have a composition such that it will leave a non-smeared surface after use and without particles of the material being left on the window.
