The electric version of the Stagg pour-over kettle, the minimalist Stagg EKG, gives you ultimate control.
Its the same great kettle but with the added electric variable temperature control.
Hand wash kettle after each use, using only warm water or a combination of water and dish washing detergent. Do not use chlorine, bleach, or other chemicals. Let kettle air dry or towel dry thoroughly. If any sign of corrosion is discovered, apply some compounding polish on a soft sponge and rub. Rinse thoroughly after cleaning. If any sign of water deposits form inside the kettle, a 50/50 vinegar/water solution works wonders and should remove these bits. Rinse thoroughly after cleaning.
