We know you're excited to use your new filter, but please rinse it thoroughly before the first use.
How to Make Your Cloth Filter Last
Get rid of as much of the coffee as possible
A thorough rinse in hot water should be enough. If you do decide to use soap, use a washing up liquid. Do not put it in with your laundry, you’ll never get the smell of detergent out!
Boil in fresh water every month or so to remove any built up oils. Adding Cafiza or similar product will get your filter looking and tasting as good as new!
If your filter stays damp for too long, it will start to smell, so there are three options:
Good: leave it to dry, and store it dry.
Better: store it in water in the fridge.
Best: put it in a container while wet and store it in the freezer.
