Pane and glass cleaning
Glass surfaces must be professionally and properly cleaned according to their degree of soiling. For this purpose, in particular a sufficient amount of clean water is to be used.
Other methods of glass cleaning should only be considered if the use of much clean water is not sufficient. However, aggressive cleaning agents (for example, alkaline detergents, hydrofluoric acid and fluoride containing detergents) must be avoided because they irreparably damage the glass or the glass surfaces.
Cement sludges and all other secretions of building materials are to be removed immediately, because even then the glass surfaces can be irreparably damaged or later damage to the glass can be caused.
Scratching tools, razor blades and scrapers are not suitable because they can cause scratch marks in the surfaces. In particular, so-called “blading” is not a proper method for cleaning entire glass surfaces.
For multi-pane insulating glass with coated outer surface special cleaning regulations apply.
“Normal” contaminants are to be removed as just described, however, no abrasive cleaning material, e.g. abrasive or commercial steel wool, can be used.
Persistent soiling, e.g. paint or tar splashes or adhesive residues should be treated with suitable solvents, e.g. alcohol, acetone or benzine, dissolved and then cleaned. When cleaning with solvents, care must be taken not to damage seals or other organic materials.
For soiling that can not be eliminated with the cleaning measures described above, please contact your ISOLAR® Glass Partner.
