Depending on the material, some skewers are easier to clean than others. Shish kebabs made of stainless steel can easily be cleaned by hand and a little washing-up liquid or detergent, or even in the dishwasher, as stainless steel is rustproof.
Wooden skewers, on the other hand, are particularly suitable for dishes in the pan or oven and are simply thrown away after the meal. Here, therefore, cleaning and multiple use is not possible.
