Reusable water bottles: At least once in your life you’ve bought a reusable water bottle before. It’s great for the gym, school and work.

Wooden cutting boards: This is a big no-no because dishwashers can get pretty hot, and cutting boards will morph and crack if they're exposed to a lot of heat. Another thing to look out for when it comes to your cutting board is bacteria. Just like cracks in walls are a playground for bacteria, cracks in cutting boards are also a breeding ground for bacteria buildup like mold. Just think about it: Old food particles are on the board, and if you put it through the dishwasher, it would crack, causing the food particles get stuck. This causes bacteria to feed off of the old food. Yuck! If that happens, throw the cutting board away. It is best to wash wooden cutting boards by hand and with a little elbow grease.
