In order to avoid damaging glass, as well as maintain its surface condition and clarity of vision, glass should be protected during all stages from manufacturing to final installation. Everyone understands that glass can be broken, but few people know how improper care can damage its performance.

Most of damage occurs early in the life of the glass, very often during the construction process. In each phase, starting from production and ending with final installation and maintenance, glass risks several hazards that can affect its performance and properties. 

Glass production
Glass can be damaged during production due to several causes. However this material is quickly identified and generally does not leave the manufacturing plant. It is crushed and reused as cullet. 

Glass storage
During storage, glass is vulnerable to permanent surface damage in the form of staining. Staining is caused by a chemical change or degradation of the glass surface. In some cases it may also evolve into an etching that can severely damage the glazing surface. When water enters between panes of glass, it remains blocked and cannot drain away. As the water starts to evaporate slowly, it forms a concentrated alkaline solution, which causes staining. It is therefore important that glass is stored indoors in a dry, ventilated location. 

Construction
During building construction glass should be protected at all times to avoid harmful construction debris, such as paint, plaster and concrete from coming into contact with the glass surface. There are several protection methods that have been implemented through the years. These methods include everything from installing glass after all painting and plastering has been completed to covering the windows with different products such as plastic sheeting, papers and oils. 

Cleaning after construction
After the production phase is completed glass should be properly cleaned. There are several differences between ordinary glass cleaning and cleaning after construction. These processes mostly involve removing construction debris from glass without scratching it. This is a delicate procedure, which should be carry on by specifically trained professionals. 

Maintenance
This process involves regular and proper glass cleaning.
