Drying Out, Cleaning and Storage
When not in use, remove the inner wallet from the outer cover and allow to completely dry out naturally until the gel returns to crystal form. To keep the crystals separate, give the wallet an occasional shake whilst drying out. Note: the drying out period can take 2-4 weeks depending on the environmental climate.
To accelerate the drying out period, various methods can be used: 1) place near (but not too near) a heat source; 2) hang the wallet on a clothes line if the weather is suitable; 3) leave on a window sill in a sunny position; shaking at intervals will help. DO NOT PLACE THE FRIO WALLET IN A TUMBLE DRYER!
The outer cover of the wallet can be washed in warm water using a very mild detergent. The inner wallet can be spot cleaned by using a soft bristle brush (i.e. soft toothbrush or nail brush): dip the brush into slightly soapy water and spot clean the wallet. You can then rinse the wallet under running water without damaging the crystals inside. Alternatively, you can use a non-bleach anti-bacterial cleaning spray or an anti-bacterial kitchen or baby wipe to clean your wallet. DO NOT PLACE THE FRIO WALLET IN A WASHING MACHINE!
Store your FRÍO wallet in a dry place until you next wish to use it.
These instructions are only a guide. Due to varying climatic and environmental conditions around the world, FRIO wallets will respond differently according to location. If activated and used sensibly they will continue to respond to your needs over a long period of time. With age, the length of immersion time will increase but as long as the crystals expand into a gel the wallet will function properly. When the crystals fail to expand, the wallet will need to be replaced.
