IMPORTANT: DO NOT use any kind of soap or detergent to clean the cloth filter, because it will leave undesirable taste in the cloth material which will be transferred to the brewed coffee as well. Alternatively you can clean the cloth filter by rubbing it in salt and rinsing it in warm water every once in a while. Note: It is normal for the cloth filter to get stained and change its color to dark brown after a few uses due to the oils that get released from the coffee grinds during the brewing process, That will not affect the function of the cloth filter nor the taste of the brewed coffee in any negative way. On the contrary, traditionally it's believed that the longer a cloth filter has been used to brew coffee the better the taste of the coffee will get.
