When washing, the water hardness should be approx. 0 °dH.
Correct dosing of rinse aid and detergent – we recommend at least one annual inspection of all dishwashers.
Dairy products, milk, coffee, hot chocolate, tea and fruit juices can leave an ‘edge’ on the prod-uct (a so-called ‘office cup’). To deal with this, place or wash the glass in warm soapy water immediately after use or use our cleaning product Renovate Powder on a regular basis.
The following may discolour the unbreakable glasses, make them cloudy or change the smell in the long run:
Washing at more than 85 degrees over a long period of time
Keeping the glasses for a prolonged period of time at high temperatures and high humidity – we recommend that you empty the dishwasher immediately after washing.
Use of detergent containing alu or metal protection.
Use of wrong draining tray for the glasses (do not use the trays for cutlery or plates). You may use the cutlery basket cover grid for small, light products.
- Use of anise-based drinks (such as Pernod, Ricard, Raki or Ouzo) or beverages with a high ester content. Esters are a natural product often found in e.g. herbal teas.
Discoloured circles in the glass or different smell in the glass?
Milk products, coffee, chocolate milk, tea and other similar hot beverages can leave a rim on the glass – especially if the glass is not washed after use for a long period (a so-called "Office Cup"). The glass is not stacked correctly – not designed to be stacked. Using a drink with a high ester content can enter “into” the glass and smell. Ester is a natural product and is found in large quantity in fruit tea.
Are there scratches in the glass?
May be due to: Selecting the wrong glass dish tray or lack of lid for dish tray. The glass rubs up against each other or other items doing washing. Use of sponge, brush, etc. that can scratch the plastic. The glass is not stacked correctly – not designed to be stacked. Use of soap with aluminum and metal protection. Dropped on hard surface – plastic gets scratched.
Is the glass cloudy?
May be due to: The hardness of the water is more than 0 ° dH. Missing or incorrect dose of the rinse or/and washing detergent. Wash at over 85 degrees for an extended period of time (final rinse). Longer storage time at high temperature and high humidity. Use of soap with aluminum and metal protection. Euphoric substances/drugs have been entered into the glass - creating a chemical reaction that breaks down the plastic
