To maintain the shine, polish your utensil gently – after a month or two of usage – by applying a small quantity of liquid cooking oil on a soft brush or cotton cloth and rubbing the wooden utensils with it. After, let it dry.

PS: It is normal for the items to look washed up (ashy) after being washed severally as the soap removes the oil that gives the wood items the shinny look. Additionally, avoid scrubbing using iron/steel wool.
