    Cutting Boards

    Cutting boards are a staple in every kitchen, but they can also be a breeding ground for harmful bacteria. Wooden cutting boards, in particular, are porous and can absorb juices from raw meat, poultry, or fish, allowing bacteria to multiply. To keep your cutting boards clean, wash them thoroughly with hot, soapy water after each use. Consider using separate cutting boards for different food groups to prevent cross-contamination. Additionally, periodically disinfect your cutting boards with a mixture of water and vinegar or a food-safe disinfectant.

    Kitchen Sink

    It may come as a surprise, but your sink harbours more bacteria than most other areas in your kitchen. With food particles, dirty dishes, and constant exposure to moisture, your sink becomes a breeding ground for harmful microbes. To keep it clean, regularly sanitize the sink and the surrounding countertops. Scrubbing with a mixture of baking soda and water can work wonders in eliminating stubborn stains and odours. Additionally, the sink faucet handles are frequently touched with dirty hands, further contributing to contamination. Regularly disinfect your sink and faucet handles with a disinfectant cleaner or a mixture of bleach and water. Ensure you're also cleaning the sink strainer, which can accumulate food debris.

    Dish Sponge and Dishcloth

    Your kitchen sponge and dishcloth may be doing more harm than good if not cleaned and replaced regularly. These items can quickly become breeding grounds for bacteria due to their damp and porous nature. To prevent this, microwave your sponge for about two minutes every few days or replace it every week. Dishcloths should also be laundered frequently to ensure they are not spreading bacteria around the kitchen.


    The fridge is where we keep our food, but it can also turn into a germ and mould party zone. Accidental spills and forgotten leftovers can mess up the shelves and drawers over time. To keep your fridge nice and clean, take out everything, even the shelves and drawers, and give them a good wash with warm, soapy water. Inside the fridge, use a mix of water and baking soda to wipe away smells and make things germ-free. Now, the rubber seals around your fridge and freezer doors might not be something you think about much, but they can become dirt and germ magnets. They can grab onto crumbs, spills, and moisture, which can turn into a yucky situation. So, don't forget to give those seals a regular cleaning with warm water and mild soap to stop mould from growing and to keep them doing their job of sealing the doors tight.

    Can Opener

    The can opener is an often-neglected kitchen tool when it comes to cleaning. Food residue can accumulate on its blades, leading to contamination of your canned goods. After each use, make sure to wipe down your can opener, paying special attention to the blades. If it's dishwasher safe, even better - run it through a cycle to ensure thorough cleaning.

    Coffee Maker

    Many people rely on their coffee makers daily, but these machines can also be a breeding ground for mould and bacteria. The dark, damp interior of a coffee maker, coupled with warm temperatures, provides an ideal environment for microorganisms to thrive. Clean your coffee maker regularly by running a mixture of equal parts vinegar and water through it. To keep your coffee maker clean, wash the removable parts, such as the carafe and filter basket, after each use. Run a mixture of equal parts water and vinegar through the machine once a month to descale it and eliminate any buildup. Be sure to follow the manufacturer's instructions for cleaning and maintenance.


    Cooking often results in splatters and spills on the stove and inside the oven. If not cleaned promptly, these residues can harden and become challenging to remove. Oven knobs and handles are often touched with greasy or dirty hands during cooking. Over time, they can accumulate a thick layer of grime that's not only unsightly but also a potential source of contamination. Wipe down oven knobs and handles with a degreaser or a mixture of baking soda and water. For stubborn stains, use a soft-bristle brush.

    Furniture Pieces

    Various furniture pieces adorning your kitchen, such as dining chairs, tables, wooden bar stools with backs, and cabinets can accumulate dust and grime, while also collecting food particles. To maintain a bar stool with a backrest, dust it regularly with a microfiber cloth or a soft brush. For deeper cleaning, wipe them down with a damp cloth and mild soap, while making sure to clean the corners and crevices thoroughly. Use furniture-grade cleaning products and consider applying furniture polish or wax to protect and enhance the finish of wooden furniture.

    Trash Can

    The trash bin in your kitchen works quite like a magnet for dirt and germs as it collects all the waste. Even if you use a plastic bag inside the can, spills and leaks are a common phenomenon, which can further lead to foul odours and a dirty mess. To deal with this, make sure you clean your trash can often, both on the inside and the outside. You might also think about using trash bags that have scented liners to cover up any bad odours. Lastly, make sure to always tie up and take out full trash bags quickly.

    In the hustle and bustle of daily life, it's easy to overlook the hidden corners of your kitchen that secretly harbour dirt and germs. However, by acknowledging and addressing these often-neglected areas - from the kitchen sink to cutting boards and everything in between - you can ensure a safer and healthier cooking environment. Regular cleaning and maintenance routines for these spots will not only help you prevent illness but also go a long way in keeping your kitchen sparkling and safe.
