Mistake 4: Tossing any kitchen tool into the dishwasher
Why it’s dirty: Smaller kitchen tools like a garlic press, zester or cheese grater have small nooks and crannies that a dishwasher isn’t always able to blast. When food is left in these tools, it can become moldy and get into food the next time it is used.
How to fix it: Skip the dishwasher and wash by hand with dish soap and hot water, paying particular attention to corners and small holes.
