Generally, irregularities in the glass can be sanded down and washed off before the glass is heated in the tempering oven.

For example, a professional window cleaner may begin cleaning a defective tempered glass pane without knowing about the presence of fabrication debris. The debris will often dislodge and scrape across the surface as the window cleaner wipes and polishes the window pane.
