Only Chimay bottles remain on the line.

These will all be transported to a bottle washer containing 16,000 bottles, all emptied of their residue, pre-rinsed, then passed through successive baths of caustic soda at high temperature.

At the end, every bottle has been rinsed twice and washed out with injections of sterile water. The result is perfectly clean bottles, thoroughly disinfected and with their labels removed.
