A common question often encountered by home cooks is, "Should I put the chopping block in the dishwasher?"


The simplest answer is No.


The long-term answer is that there is a proper way to clean your chopping board, depending on the type of material on the chopping board. The following is a list of commonly used cutting board types and how to clean each of them:


Wooden chopping board (maple, oak, cherry, walnut, etc.)


Wood is by far the most popular chopping board material. Most wood cutting boards consist of glued edge or wood grain telomeres. The main reason not to put the board in the dishwasher is that prolonged exposure to heat and water can cause warping and cracking of the cutting board. Not only is it difficult to cut on warped wood, but cracks in wood are a breeding ground for bacteria, mold, and other microorganisms that feed on captured food particles and water.


The safe and correct way to clean the cutting board is to clean it like any regular plate, like using lots of hot water (hotter, better), soap and mechanical scrubbing (aka "put your elbow in!"). If the circuit board has been exposed to raw meat, after the cleaning is complete, use 1 part vinegar, 4 parts water disinfectant solution and wipe the board dry, then pat dry. If you want to be more certain, the U.S. Department of Agriculture recommends using a tablespoon of bleach per gallon of water for a few minutes, then wipe dry with a cloth or paper towel.


One of the most important aspects of maintaining wooden chopping boards is to maintain proper oiling. By feeding the cutting board with oil, you can extend the life of the wood, prevent cracking of the wood due to over-drying, and prevent warping of the wood due to rapid changes in wood moisture (also known as cupping). If your board dries too long and suddenly exposes it to water, it is usually the culprit behind the warping block.


Another reason for regularly applying oil to the cutting board is for hygiene because the oiled board resists foreign liquids such as blood and related bacteria immersed in the wood. You should always use food-safe or food-grade mineral oils instead of vegetable oils because it will damage and cause your chopping board to stink.


Plastic cutting board


The main advantage of plastic chopping boards is that plastic chopping boards can be placed in the dishwasher because they won't warp or break (minus the thin plastic sheet). This is actually the recommended method for plastic cutting boards, because plastic boards usually have more knife marks, which will cause more bacteria to hide in the corners. Please note that not all dishwashers


Another option, such as the dishwasher is not available or preferred, should be washed with hot water and soap, and then rinse the plate with bleach or vinegar disinfectant for several minutes. Unlike wood planks, you can leave plastic panels anywhere, although it may take up to 5 minutes to ensure proper disinfection.


Glass cutting board


Like plastic, a glass plate can also be placed in a dishwasher because glass is a hard material that does not bend. That is to say, we always think on CuttingBoard.com that we have to mention the fact that the glass cutting board can only be used for decoration or light use, because if used on a glass board, the blade will eventually become blunt. You should never use hard inserts on glass, such as ceramics, because the risk of chipping is very high, and there is a dangerous knife in the food!


Bamboo chopping board


While most people wrap bamboo panels along side wooden blocks (implying that bamboo is technically not considered wood), bamboo cutting boards behave in much the same way as wood. Bamboo plates are made in a special way and require a lot of glue and pressure to flatten the bamboo, which makes them particularly vulnerable to heat and moisture inside the dishwasher. If you put a bamboo plate in the dishwasher, don't be surprised if you eventually need a new one.


In other words, compared to most hardwoods, bamboo cutting boards are very hard and dense, so using a bamboo board to do a little will be helpful!
