Potato Mashers are generally easy to clean and maintain. Most models are suitable to clean in the dishwasher, and it’s important to wash after each use since these products are designed to intimately mash and break up food. The holes in perforated models provide ample nooks for bacteria to cling to and breed if not cleaned properly, and it’s important to ensure that food is thoroughly washed away after use. Before tossing in the dishwasher we recommend a thorough rinse under the faucet.
If you don’t have a dishwasher at your disposal, make sure to use a sponge to scrub the potato masher completely. Dishwashing soap and warm water will do just fine. We like to soak our potato mashers after each use in soapy, warm water for around 10 minutes before removing and drying thoroughly with a fresh dish cloth.
Wave shaped potato mashers require a more delicate touch than other models. They are generally less sturdy than perforated models and ricers, and can bend under pressure, so make sure that when stored it’s not being crushed underneath heavier tools and appliances.
