How often should I clean my CoffeeSock filter?
Rinse as soon after use as is convenient and hang to dry. Oil build-up will increase with ground contact time. To remove oil build up, we suggest boiling your filter every 6-8 weeks (or as is necessary) to remove any oil build up. Boil for 10 minutes in fresh water. Repeat if build up is heavy. Add a teaspoon of baking soda or distilled vinegar to the boil to freshen, as is necessary.
Can I wash my CoffeeSock filter in the washing machine?
We don’t recommend it, as detergents will flavour your brew.
Can I use dish soap to clean my CoffeeSock filter?
We don’t recommend using soaps because it will leave a soapy residue and end up affecting the flavour of your brew.
Are the CoffeeSocks bleached?
No, the fabric is unbleached. CoffeeSocks are made of 100% organic cotton.
Is my filter compostable?
Yes! You can add to your compost bin. Cutting filter into 1 inch pieces will hasten decomposition.
My CoffeeSock seems clogged, why is the flow so slow?
This may be a result of a change in grind sizing. We recommend medium coarse to coarse grounds. Alternately, this may be due to oil build up. Over time your filter will begin to develop an oil build up. This can result in a slower flow. To remove oil build up we suggest boiling your filter every 6-8 weeks (or as is necessary). Boil for 10 minutes in fresh water. Repeat if build up is heavy. Add a teaspoon of baking soda or distilled vinegar to the boil to freshen, as is necessary.
How long will my CoffeeSock filter last?
Your filter can last up to a year or more. We typically suggest replacing your filter after 9-12 months.
Does the CoffeeSock remove oils?
CoffeeSock filters will remove more of the coffee oils than you would find in a French Press brew, but less than paper. This is based on observation and taste tests. Lab testing has not been done.
What's the best way to clean my CoffeeSock?
All that is necessary is to simply rinse, reuse, and occasionally boil your filters to remove build up, but for a deeper clean, use these eco-friendly cleaning tablets - formulated from all-natural, organic, biodegradable and phosphate-free ingredients that eliminates oil build-up in CoffeeSock filters.
Once every 6-8 weeks, boil filter(s) with 1 tablet in fresh water for 10 minutes to remove built-up of coffee oils. Repeat a fresh water boil for 5 minutes. Rinse with clean water and hang to dry.
