What to Do in the First 15 Minutes

When you’re faced with cleaning vomit from a mattress, the clock starts ticking immediately. Those first few minutes are absolutely critical. My years of cleaning mattresses across Melbourne, from Brunswick to Brighton, have taught me one thing above all else: a fast response is what stops a small accident from becoming a permanent stain and a lingering odour.

First things first, get rid of any solid matter. Do not wipe or rub! I can’t stress this enough. Wiping just grinds the acidic mess deeper into the mattress fibres. Instead, grab a paper plate or a spatula and gently scrape everything you can into a plastic bag to throw away. And please, put on some disposable gloves – it’s a messy job.

Gather Your First-Aid Kit

Once the surface is clear, it’s time to tackle the wet spot. You don’t need any fancy chemicals for this initial stage. Just a few simple household items will do the trick:

• Clean, dry cloths or paper towels: You’ll need these for blotting up all that excess moisture.
• A spray bottle: This lets you apply your cleaning mix without totally soaking the mattress.
• White vinegar and cool water: This will be your first line of defence.

Mix up a simple solution of one part white vinegar and one part cool water in your spray bottle. This combo is fantastic for starting to break down the acids in the vomit. It’s gentle enough that it won’t set the stain, which is a real risk if you use hot water or harsh chemicals straight away.

Over its lifespan, an average mattress endures thousands of nights of use, making accidents almost inevitable. Australian consumer advice highlights that acting quickly—preferably within 24 hours—is the single most important factor for successful stain removal.

Lightly spritz the affected area with your vinegar solution. You just want to dampen it, not drench it. Now, take a clean, dry cloth and blot the area firmly. You should start to see the cloth pull up the moisture and the stain. Keep blotting with fresh, dry sections of the cloth until nothing more is transferring.

Getting this first response right makes all the difference and sets you up for a much more successful deep clean later on.

Getting Rid of the Stain and Smell with a Few Kitchen Staples

Once you’ve dealt with the initial mess, the real work begins: tackling the stain and the lingering odour. I’ve been cleaning mattresses across Melbourne for over 15 years, from Footscray to Frankston, and I can tell you that you don’t need a cabinet full of harsh chemicals. Often, the best solutions are already in your kitchen pantry.

Vomit is highly acidic, which is why it’s so notorious for bleaching and damaging mattress fabrics in a flash. The trick is to neutralise that acid with something alkaline. This is where plain old baking soda—a true hero of home remedies—comes into play.

How to Make and Use a Cleaning Paste

Whipping up the paste is easy. Just grab some baking soda and mix it with a small amount of cool water. You’re aiming for a consistency like thick toothpaste.

Gently spread this paste over the entire stain. You want to cover it completely, but there’s no need to rub or scrub it in. Just let the paste sit on top of the fabric.

Now, you need to let it dry completely. This part requires a bit of patience as it can take a few hours, but this is when the magic happens:

• The alkaline baking soda gets to work neutralising the acidic vomit stain.
• As the paste dries, it wicks the moisture and the source of the odour up and out of the mattress fibres.

Once it’s totally dry and crumbly, grab your vacuum cleaner, pop on the hose attachment, and suck up all the dried powder. You’ll be amazed at the difference in both the appearance and the smell.

This image really highlights the best way to handle moisture on a mattress—blotting, not rubbing.

As you can see, gentle blotting lifts the liquid away. If you rub, you risk pushing the stain deeper into the mattress, making it much harder to remove.

For some extra peace of mind, you can finish with a light misting of 50/50 white vinegar and water. Let it air dry completely. Vinegar is a fantastic natural disinfectant that helps kill off any stubborn bacteria left behind.

From my experience, I’ve found that some common household products work better than others for specific situations. Here’s a quick guide to help you choose the right tool for the job.

Using the right product in the right way is key. When in doubt, start with the gentlest method—baking soda is almost always the safest and most effective first step for a fresh accident.

How to Properly Dry and Sanitise Your Mattress

You’ve tackled the stain and the smell, which is a massive win, but don’t put the sheets back on just yet. Dealing with the dampness left behind is every bit as critical. A moist mattress is the perfect breeding ground for mould and mildew, and that’s a whole new set of problems you really don’t want to deal with.

Getting the mattress completely dry is your number one priority now. I’ve seen it time and time again, from St Kilda to South Yarra—people rush this part and always regret it later when that musty smell appears.

Let Air and Sun Do the Hard Work

If you’re lucky enough to get a beautiful sunny Melbourne day, you’d be mad not to use it. Haul that mattress outside and lean it up against a wall or a couple of chairs. The fresh air provides fantastic ventilation, and the sun’s UV rays are a brilliant natural disinfectant, helping to knock out any stubborn bacteria that might be hanging around.

Of course, we all know Melbourne weather doesn’t always play fair. If it’s an overcast day or you’re in a CBD apartment without a balcony, you’ll need a solid indoor plan.

• Get the Air Moving: Throw open any windows in the room and point a fan or two directly at the damp spot.
• Bring in a Dehumidifier: If you’ve got one, park it right next to the mattress. These things are incredibly good at pulling moisture right out of the fabric and the surrounding air.

I can’t stress this enough: your mattress must be 100% dry before any bedding goes back on. Even a tiny bit of lingering moisture can blossom into a big, mouldy problem down the track.

Once it’s dry, the final step is to make sure it’s not just clean, but properly sanitised. A thorough vacuum over the entire surface is a great final touch. This is also a good moment to think about overall mattress hygiene. Experts generally recommend having your mattress professionally cleaned at least twice a year to keep dust mites, germs, and other nasties under control for better health and sleep.

Following these drying and sanitising steps gives you complete peace of mind, knowing your bed is a genuinely clean and hygienic place to rest. For more general advice, you might find our complete guide on how to clean a mattress helpful.

When a DIY Fix Is Not Enough

Sometimes, even with all the best intentions and elbow grease, a DIY clean just doesn’t cut it. That stubborn stain refuses to budge, or worse, that horrible smell creeps back just when you think you’ve won. After 15 years of cleaning mattresses all over Melbourne and its suburbs, I’ve seen it all. I know exactly when a home remedy, while a great first response, simply isn’t powerful enough for the job.

You’ll know it’s time to call in a professional when you spot these tell-tale signs:

• That sour, lingering odour makes a comeback after the mattress feels dry.
• A distinct yellow stain or discolouration just won’t fade away.
• The original accident was quite large, meaning it has probably soaked deep into the core of the mattress.

Why Professional Cleaning Makes a Difference

As a specialist covering all of Melbourne’s suburbs, from Werribee right out to the Dandenong Ranges, I can tell you that calling for help isn’t admitting defeat. It’s about protecting your mattress investment and, more importantly, your family’s health.

The truth is, no amount of dabbing or surface scrubbing can match what our equipment can do. We use professional-grade hot water extraction machines that get right down into the mattress fibres, flushing out contaminants that are hiding deep inside.

These machines work hand-in-hand with powerful, non-toxic enzymatic cleaners. These aren’t your average household products; they’re designed to completely destroy the organic matter left behind by vomit at a microscopic level. This is what truly eliminates the odour for good, rather than just masking it. While you can find some great DIY mattress cleaning approaches, there are times when you really need the heavy-duty solution.

Because vomit contains stomach acids and bacteria, it’s a unique challenge. If it’s not treated properly, it can become a health hazard. Professional cleaning using enzymatic formulas is the only way to properly break down this kind of organic matter and thoroughly disinfect your mattress.

A professional clean is your guarantee that every last bit of the contamination is gone. It restores your mattress to a hygienic state and gives you complete peace of mind. My goal is to make sure every household in Melbourne has access to a genuinely clean and safe place to sleep.

Common Questions About Cleaning a Mattress

Over my 15 years in the mattress cleaning game, I’ve made it my business to provide a top-notch mattress stain removal service to Melbourne and its wonderful suburbs. From apartments in Fitzroy to big family homes out in Essendon, I tend to get asked a lot of the same questions.

My training and hands-on experience in this field are extensive, and I’m always happy to share what I’ve learned from my time on the road helping families across Melbourne. Here are my answers to the most common queries I get from clients figuring out how to clean vomit from a mattress.

Can I Use a Steam Cleaner on the Stain?

I’d strongly advise against it. The intense heat from a steam cleaner can literally cook the proteins in the vomit. This sets the stain permanently into the mattress fibres, making it next to impossible to get out later.

Heat also has a nasty habit of locking in odours, which is the last thing you want. Always stick to cool or lukewarm water for this job.

Will These Methods Work on a Memory Foam Mattress?

Yes, they will, but you have to be much more careful. Memory foam is like a giant sponge—far more absorbent than a traditional spring mattress.

You have to use any liquids very sparingly. Your focus should be more on blotting and using dry products like bicarbonate of soda. If you oversaturate memory foam, you risk damaging its structure and you’ll be left with a mattress that takes forever to dry properly.

When in doubt, it’s always best to call a professional who understands the specific needs of different mattress materials. My team and I are dedicated to serving all of Melbourne’s suburbs, ensuring every job is done right.

If you’ve tried a DIY fix and a stubborn smell is still hanging around, it’s a sure sign the bacteria have worked their way deep into the mattress. At this stage, a professional deep clean is the only real way to fully sanitise the mattress and get it back to its best.
