Are Can Openers Dishwasher Safe: The Hidden Truth - Maria's Condo

A can opener is an essential kitchen tool, making everyday tasks more convenient. Whether you are opening a can of your favorite soup or a bottle of beer, a reliable can opener makes the job easier and faster. This article is a comprehensive guide to understanding different types of can openers, their usage, safety measures, and cleaning practices.


Types of Can Openers

Can openers come in various forms, each designed to meet specific needs. They are broadly classified into two main types: manual and electric.

Manual Can Openers

Manual can openers are the most popular option as they are easy to use and save space. They feature a stainless steel cutting wheel or blade that neatly accesses the contents inside the can without causing injury or requiring significant effort. Certain multi-function can openers not only cut through lids but also have an attached bottle opener.

The manual can openers have a simple design and an easy-twist mechanism, ensuring cans are opened without much hassle. Some models come with a non-slip base pad, which helps keep the jar in place without additional force.

On the other hand, some manual can openers require a little more effort than other cutters. However, their sharp cutting edge easily pierces the can lid, and the cutting continues with a slide-and-rock motion of the tool as you rotate the can counterclockwise. It may take a couple of tries to nail the technique.

Electric Can Openers

Electric can openers are ideal for those with limited hand mobility. All you need to do is press a button to start the can opener and another button to stop. They can work on all-size containers from 2 inches and larger. Despite taking up some valuable counter space and requiring an outlet, electric can openers are a great choice for people who prefer a safety can opener, which creates smooth edges.

How to Use a Can Opener

Using a can opener might seem like a no-brainer. However, the "correct" way to use a can opener can eliminate potential issues altogether. For a basic can opener, instead of clamping the handheld tool onto the side of the can, you simply place the can opener horizontally, on top of the unopened can.

Turn the knob to cut open the top, and you'll find that the entire top comes off cleanly in one fell swoop. No digging required and no sliced fingers. However, this method is not inclusive of all can openers, and you still need to heed any sharp edges of the opened can at all times.

Safety Measures

Despite their utility, can openers can create hazards. The conventional can openers often produce lids with sharp and jagged edges. Sharp edges can mean painful cuts, sweater snags, or torn holes in your recycling bags.

For those who prefer safety, a smooth edge can opener may be a good option. These openers cut through the side of the can rather than the top, producing lids with smooth, safe-to-touch edges.

Choosing the Right Can Opener

When it comes to choosing a can opener, consider factors like ease of use, durability, and value. The best manual can opener, like the EZ-Duz-It, is cheap, lasts a lifetime, and works like a champ every single time. However, for those unable to use a standard two-handed model, a battery-operated electric tool can be a good option.

For left-handed people, some companies make products specifically for home cooks who are lefties, including a simple, unfussy handheld can opener designed to be gripped in the right hand and cranked with the left.

Cleaning a Can Opener

Regardless of the method you prefer, ensure the can opener you are using is clean. A dirty blade could introduce bacteria like salmonella or E. coli into your food. Most handheld can openers can't be put in the dishwasher.

To clean them, wash with soap and warm water after every use. Use a small brush to clean hard-to-reach areas, like the gears and blade, or caked-on food. Dry completely before storing to prevent rust.

Dealing with Rust and Gunk

For rust and gunk, soak the handheld can opener or the removable cutting wheel of an electric can opener in vinegar for a few minutes. Then carefully use a brush to scrub with warm water and soap, and dry thoroughly.

A few drops of mineral oil can be used to lubricate the gears and keep your can opener working like new and help prevent rust.


Can openers are a staple in every kitchen. While they might seem like a simple tool, knowing how to use them correctly can make your kitchen tasks more efficient and safer. Moreover, proper cleaning and maintenance can extend their lifespan. So, choose wisely, use correctly, and maintain regularly.
