The present disclosure describes spill retention mechanisms for cooktops and other substrates. The spill retention mechanisms can hinder the movement of liquids primarily due to the physical attributes of the mechanisms, unlike hydrophobic mechanisms which hinder movement primarily due to the chemical attributes of the hydrophobic material.
