How should I prepare the cloth filter before using the flannel dripper for the first time?

In a kitchen where water is set to boil in a new kettle and you face the dripper for the first time — unlike paper filters, there is a process a cloth filter must go through before brewing the first cup. Before using Azmaya's flannel dripper for the first time, you must rinse it with hot water or boil it thoroughly to wash it^[1]. At this time, you must detach the wooden handle and separate only the cloth filter part to boil it^[2]. This is because if the solid wood handle comes into contact with boiling water, the wood easily warps or cracks.

The reason for boiling a new cloth filter in boiling water is to remove the starch and lingering odors remaining in the fabric. If you use laundry detergent or soap, the fragrance permeates into the gaps between fibers and ruins the coffee's original aroma, so boiling it only in plain water is standard. Azmaya completed this form by reproducing exactly the nel drip method used at the historic 'Daibo' coffee shop in Omotesando, Japan^[3].

hmmm, the hassle of untying the handle and boiling the cloth is a delicate preparation made to bring the deep, heavy cup of a historic famous shop into everyday life.
