If you want to extend the useful lifespan of your glassFORever products, you must treat them well. Here is some good advice.

1. Use the same dishwasher powder/tablets that your machine normally uses but read our washing instructions.
2. When washing by hand, make sure to use a soft sponge, brush or  microfibre cloth. It is not necessary to use a particular dishwasher liquid, but we recommend using our own product, Renovate Powder.
3. To remove any soap residue, rinse the product in clean water and dry the last drops with a soft, damp sponge, cloth or a tea towel.
4. Do NOT use petrol, alcohol, ester or organic  solvents to clean the products.
5. Direct sunlight for a long period can discolour plastic.
