You Never Wash It and It’s Full of Bacteria: The Garment Nobody Thinks to Clean
Published by WizeMind Australia | March 2026
The kitchen is where we nourish ourselves and the people we care about, which makes it worth paying attention to what the tools we use every day are actually made from. Research over the past two decades has raised legitimate questions about certain materials found in common kitchen items, and while the science is not always as dramatic as headlines suggest, there are practical and well-supported reasons to make some straightforward swaps. Here is an honest look at seven categories of kitchen equipment that warrant reconsideration, along with the evidence behind the concern and the alternatives worth considering.
1. Scratched or Worn Non-Stick Cookware
Non-stick pans revolutionised home cooking, but the chemical story behind the coating has become considerably more complicated over time. Traditional non-stick coatings were manufactured using perfluorooctanoic acid, known as PFOA, a compound classified as a possible human carcinogen by international health agencies and linked in occupational exposure studies to kidney and testicular cancer. PFOA has been phased out of manufacturing in most countries including Australia, but older pans purchased before this transition may still contain it.
The more current concern relates to what replaced PFOA. The broader class of chemicals known as PFAS, or per- and polyfluoroalkyl substances, are still used in many non-stick products and have attracted increasing regulatory scrutiny globally. The risk from non-stick cookware is most significant when pans are scratched, used at very high heat, or significantly worn, as this accelerates any release of coating particles or chemical breakdown products.
If your non-stick pan is showing scratches, peeling, or significant wear, replacing it is a reasonable precaution. Cast iron, stainless steel, and ceramic alternatives perform well for most cooking purposes and carry none of the same chemical concerns.
2. Plastic Food Containers Not Labelled BPA-Free
Bisphenol A, or BPA, is a synthetic compound used to harden certain plastics and is found in many food storage containers, particularly older ones. It is classified as an endocrine-disrupting chemical, meaning it can interfere with hormone signalling in the body. Research has linked BPA exposure to increased risk of certain hormone-sensitive cancers including breast and prostate cancer, as well as developmental effects.
The migration of BPA from plastic into food is significantly accelerated by heat. Microwaving food in plastic containers, putting them through hot dishwasher cycles, or storing acidic foods in them all increase the likelihood of BPA leaching. Repeated use and visible wear also increase migration risk.
Many manufacturers now produce BPA-free plastics, though some researchers have raised questions about whether BPA substitutes carry their own risks. The most straightforward solution is switching to glass or stainless steel containers for food storage, particularly for anything intended to be heated or stored long-term. The upfront cost is higher but the containers last considerably longer and carry none of the same concerns.
3. Heavily Scored or Damaged Wooden Cutting Boards
The concern with wooden cutting boards is not the wood itself, which is a safe and traditional material, but rather what accumulates in the cracks, cuts, and crevices that develop with heavy use. Deep scoring in a cutting board can harbour bacteria that standard cleaning does not reach, and certain organic compounds including polycyclic aromatic hydrocarbons can accumulate in heavily damaged boards over time. PAHs are established carcinogens associated with long-term dietary exposure.
A wooden cutting board in good condition, regularly cleaned and maintained, is not a meaningful health risk. The issue is specifically boards that have been used heavily over many years without replacement and have developed deep scoring throughout the surface. If your board has visible deep grooves running across the cutting area, replacing it is sensible.
Well-maintained wooden boards can also be lightly sanded to refresh the surface. Bamboo boards, which are harder and develop fewer deep cuts, are a practical alternative. High-quality plastic cutting boards can be run through the dishwasher for more thorough sanitisation between uses.
4. Cheap Plastic Cooking Utensils Used at High Heat
Plastic spatulas, spoons, and other cooking utensils often contain phthalates, a group of plasticising chemicals added to make plastics more flexible. Phthalates are classified as endocrine disruptors and some have been associated with increased cancer risk in research studies. Like BPA, their primary route of concern in a kitchen context is migration into food, which is accelerated significantly by heat.
Using plastic utensils for low-temperature tasks such as mixing a salad or serving cold food carries minimal risk. The concern is specifically using cheap plastic utensils for stirring hot food on the stove, serving from very hot dishes, or leaving them resting in a hot pan. At high temperatures, the plastic can begin to break down and release compounds into the food being prepared.
Stainless steel, silicone rated for high-temperature use, and wooden utensils are all safe and effective alternatives. Quality stainless steel utensils in particular last essentially indefinitely and represent a straightforward one-time investment.
5. Older Teflon-Coated Bakeware Showing Wear
The same concerns that apply to scratched non-stick cookware apply to Teflon-coated baking trays, muffin tins, and cake pans, particularly older items manufactured before the PFOA phase-out and any items showing significant coating deterioration. At the temperatures used in baking, particularly in a hot oven, coating breakdown is accelerated compared to stovetop use.
Items with visible flaking, peeling, or bubbling of the non-stick surface should be replaced. As alternatives, uncoated stainless steel bakeware, cast iron, and silicone baking mats all perform well across a range of baking applications. Parchment paper used as a liner on standard baking trays is an inexpensive and effective way to achieve easy release without relying on chemical coatings.
6. Aluminium Foil Used with Acidic or Spiced Foods at High Heat
Aluminium foil is deeply embedded in Australian kitchen habits and for most uses the risk it presents is minimal. However, research has shown that aluminium migration into food is measurably higher when foil is used with acidic foods such as tomatoes, citrus, or vinegar-based marinades, or when combined with spices like cumin and turmeric, particularly at high cooking temperatures. Elevated aluminium intake has been investigated in relation to neurological conditions and some research has raised questions about associations with certain cancers, though the evidence remains less conclusive than for some other compounds on this list.
The practical guidance from food safety researchers is not to eliminate aluminium foil entirely but to avoid wrapping acidic or heavily spiced foods in it for cooking or extended storage. Parchment paper is a straightforward substitute for most oven cooking applications. Glass containers with lids work well for storage of acidic foods in place of foil-covered dishes.
7. Older Plastic Wrap Used on Hot or Acidic Foods
Plastic cling wrap often contains phthalates or other plasticisers that can migrate into food, particularly when the wrap is in direct contact with hot food or acidic ingredients. The concern is most significant when plastic wrap is used to cover dishes going into the microwave, placed directly over hot food, or used in contact with fatty or acidic foods over extended periods.
The safer approach is to allow hot food to cool slightly before covering, to ensure plastic wrap does not touch the food surface directly in the microwave, and to use silicone stretch lids, glass storage containers with lids, or beeswax wraps as alternatives for general food storage. These options are reusable, increasingly affordable, and carry none of the same chemical migration concerns.
Making Practical Changes Without Unnecessary Alarm
The evidence behind these concerns sits on a spectrum. For PFOA in older non-stick coatings and BPA in plastics, the research is relatively robust and the regulatory response has been significant. For aluminium foil and plastic wrap in typical use, the risk is considerably more context-dependent and lower in absolute terms.
The most important principle is proportionality. You do not need to replace every item in your kitchen immediately or treat cooking as an exercise in anxiety management. Starting with the most worn and damaged items, particularly any scratched non-stick cookware or very old plastic containers, addresses the highest-risk situations first. From there, making gradual replacements toward stainless steel, glass, cast iron, and ceramic materials when items need replacing anyway is a sensible long-term approach that improves your kitchen without requiring significant upfront expenditure.
When buying new kitchen equipment, looking for items labelled PFOA-free, PFAS-free, and BPA-free, or choosing materials that bypass these concerns entirely, makes the replacement process straightforward. The goal is a kitchen that genuinely serves the people cooking in it, which means being informed about what the tools are made from and making reasonable choices accordingly.

You Never Wash It and It’s Full of Bacteria: The Garment Nobody Thinks to Clean
Published by WizeMind Australia | March 2026
Most people have one. That trusted jacket, coat, or heavy jumper that gets grabbed on the way out the door every single day through the cooler months, worn on public transport, draped over the back of office chairs, hung in crowded cloakrooms, and brushed against countless surfaces across the course of a week. And most people, if they are honest about it, cannot remember the last time they washed it.
This is not a particularly unusual habit. Outer layers feel cleaner than the clothes worn directly against the skin, and they tend not to look visibly dirty until the situation has become fairly significant. But the bacteria accumulating on an unwashed coat or jacket through weeks of daily use is a different matter from how the garment looks, and the implications are worth understanding.
The Unseen Accumulation
Every surface a coat comes into contact with contributes to its microbial load. A hand strap on the train, the back of a café chair, a colleague’s desk, the wall of a lift, a shared coat hook. Each of these encounters deposits a small but real collection of microorganisms onto the fabric. This is not alarmism. It is simply how textiles interact with the world.
The fabrics most commonly used in winter outerwear, wool, cotton, and various blended materials, are porous at the fibre level. They trap dirt, skin oils, environmental pollutants, and moisture in ways that synthetic performance fabrics often do not. This creates conditions where bacteria can multiply rather than simply resting on the surface. Sweat from the collar and cuffs in particular contributes warmth and moisture that accelerate this process.
The longer the period between washes, the higher this microbial load becomes. Skin irritation, the aggravation of existing conditions like eczema or dermatitis around collar and cuff contact points, and increased transmission risk of common respiratory viruses are all genuine although modest consequences of wearing heavily contaminated outerwear regularly.
The concern extends to the people around you as well. A heavily bacteria-laden garment placed on a shared surface or handled by someone else can transfer organisms to their hands and from there to their face. This is relevant context for any household with young children, elderly members, or anyone with a compromised immune system.
The Garments and Accessories That Share This Problem
The winter coat or jacket is the most significant offender simply because it is the largest and most frequently worn item in this category, but it is not alone. Bags and backpacks that travel everywhere with you accumulate bacteria on their exterior surfaces and handles in a similar way. The base of a bag placed on a café floor or a public toilet surface and then put on a kitchen bench is a commonly cited example of cross-contamination that most people never consider.
Scarves are worn in direct contact with the face and neck and are rarely washed with the frequency this contact warrants. Hats and gloves pick up hand-to-surface contamination every time they are put on and taken off in public. None of these items need to become a source of anxiety, but all of them benefit from more regular cleaning than they typically receive.
Finding the Right Cleaning Frequency and Method
The complicating factor with outerwear is that aggressive or frequent washing genuinely can damage fabric, distort shape, and shorten the life of a well-made garment. The goal is not to wash a winter coat every week but to establish a reasonable rhythm that keeps the microbial load at a manageable level without destroying the garment in the process.
For most people wearing a coat or jacket through an average Australian winter, washing it once every three to four weeks of regular wear represents a sensible middle ground. If you have been ill, if the garment has been heavily used in crowded environments, or if you can detect any odour, washing it sooner makes sense.
Before washing anything, check the care label. This is genuinely worth doing rather than treating as an optional step. Many wool and blended outer garments are hand-wash only or require cold water and a delicate cycle to prevent shrinkage and distortion. Using a gentle detergent formulated for delicate fabrics rather than a standard laundry detergent will help preserve the integrity of the material across multiple washes.
For garments that cannot be machine washed, spot cleaning between professional cleans is a practical approach. A damp cloth with a small amount of mild soap addresses visible marks and fresh stains. Hanging the garment in fresh air, ideally outdoors on a dry day, helps with odour control and allows any surface moisture to evaporate before the garment is stored again.
Dry cleaning is the appropriate solution for structured coats, heavily embellished garments, or anything where you are uncertain about the fabric composition. Professional cleaners also have access to steaming equipment that effectively addresses bacteria and odour without full wet cleaning, which can be useful for maintenance between washes of delicate items.
Addressing Stains and Odours at Home
Visible stains are best addressed as quickly as possible after they occur. Fresh stains are substantially easier to remove than set ones, and treating them immediately with cold water and gentle blotting rather than rubbing prevents them from being driven deeper into the fibre.
For persistent odours between washes, there are a few approaches that work well without damaging fabric. Hanging the garment in fresh air for several hours is surprisingly effective at neutralising odour caused by environmental absorption. A light misting with a diluted white vinegar solution followed by airing out addresses most odour situations. Baking soda placed inside the garment bag during storage absorbs odour passively over time. Fabric refresher sprays provide a quicker fix for odour between washes but do not address the underlying bacterial load.
Avoiding storing a coat or jacket while it is even slightly damp is worth emphasising. A damp garment folded into a wardrobe is an environment where mould and bacteria thrive rapidly. Always ensure outerwear is fully aired and dry before storing.
A Simple Self-Check
If you are unsure whether your coat is due for a wash, a straightforward assessment takes only a moment. Examine the collar, cuffs, and any other areas that come into close body contact for visible discolouration or greasiness. Check for any visible marks or staining on the main body. Then hold the collar near your face and take a gentle breath through the fabric. A fresh garment should smell of nothing much. If you detect any staleness, mustiness, or odour, the garment is overdue for cleaning.
This self-check takes thirty seconds and provides a more honest answer than simply trying to remember the last time the garment was washed.
The Practical Upside
Making a habit of cleaning outerwear more regularly than most people currently do produces a number of straightforward benefits. Skin around collar and cuff contact points is less likely to become irritated or congested. The transmission risk of common viruses through fomite contact is modestly reduced. Garments that are cleaned regularly and properly maintained tend to last longer than those that accumulate grime and are then subjected to aggressive cleaning attempts to correct the neglect.
None of this requires a significant change in how you live. It requires setting a reminder every few weeks during the months when coats and jackets are in regular rotation, checking the care label once so you know the appropriate cleaning method, and treating bags, scarves, and gloves with the same periodic attention. The invisible ecosystem living in the fibres of your favourite coat will be considerably less interesting as a result, which is entirely the point.
