Filter Angel Care
To clean the Filter Angel, simply wipe it with a damp cloth. Do not machine wash or submerge it as this could cause the wood to swell excessively.
Filter Care
Cloth filters are long-lasting and easy to maintain. The effort needed to use and maintain them is comparable to that of cleaning and maintaining any other coffee-brewing device.
Simple rinse
As you use it, its color will change to dark brown due to the coffee oils released in the brewing process. This is expected and even desired. A well-maintained and constantly-used cloth filter has a pronounced coffee aroma and provides a superior coffee flavor.
NEVER USE SOAP! NEVER USE BLEACH!
Before first use, remove any impurities left over from manufacturing by either rinsing the filter with salt and hot water or by boiling it for a few minutes.
Regular maintenance
After use, discard the grounds and rinse it in warm water. This does not need to be done immediately. Sometimes, letting the grounds sit for an hour or so actually dries them out slightly and facilitates their removal. Longer periods of drying should be avoided as it will cause the filter to become stiff and, in extreme cases, may promote off-flavors.
Discard grounds and rinse
For deeper rinse use a tub
After rinsing, wring out excess water and allow it to dry by either hanging it in the Filter Angel or placing it handle-first in a jar or glass.
Occasionally, if it has sat unused for an extended period or if it has become stiff or exhibits off-flavors, you may wish to renew its freshness by rubbing it in salt and rinsing in hot water.
Alternatively, it can be completely refreshed by boiling it for about 10 minutes in order to remove the old coffee oils. Boiling will return it to a clean-scented state, but will not remove the brown coloring.
Be careful when boiling filters with a plastic hoop. Inexpensive ones of this type will deform in hot water. The recommended 'Colador' filter withstands boiling.
The often-boiled 'Colodor' on the right is ok, while the inexpensive imitation on the left has deformed during its first boil.
