Three simple ways to prolong the life of your glassware:

Avoid thermal shock

There is nothing worse than drinking an ice cold drink out of a warm glass, but, more than this, it is actually bad for the glass.

Adding ice to a hot glass will be a temperature shock for the glass, making it more likely to crack or break; make sure that glasses have cooled down before use. Likewise, it is also not advisable to stack hot glasses from the glasswasher.

As the glasses begin to cool, the trapped air between the two glasses will try to equalise with the air pressure outside and this can result in the glass failing.


When glasses develop a cloudy texture it’s known as etching. This process is caused by continued use and cleaning in the glasswasher. There are a few steps that can be taken to avoid this happening so that glasses stay looking as good as new.

  1. Firstly, you should clean your glassware immediately after use with a specially formulated detergent.
  2. Glass renovator can be used to help limit and prevent etching; it is recommended that glass renovator is used once every four weeks to remove small scratches in glassware and prevent the build-up of rinse aid.
  3. Regular renovation will maintain the good condition of your glasses and help to keep nucleated glasses in working order.

Contaminated glasses

Poor hygiene routines will result in a build-up of residues on glassware. This causes problems such as flat drinks, lack of head retention on beers and glasses retaining odours. Washing glasses in a sink is frowned upon by many health organisations and poses risks to the operator as glasses can break.

Glasses should be washed in a dedicated glasswasher that is not used for cutlery or crockery, whilst regular cleaning and maintenance of the glasswasher is crucial for clean, hygienic glasses. After washing, it is preferable to naturally air dry, but glasses can be cleaned with a clean dry cloth can.
