Clove & Eucalyptus Mould Spray

You’ve got the bleach spray in your hand. You’ve held your breath. You’ve opened the window. You’ve sent the kids out of the bathroom.

That’s not a cleaning ritual. That’s a warning system.

Most mould sprays work through sodium hypochlorite and caustic soda — the same chemistry as industrial disinfectant. They bleach the colour out of the mould. They damage your grout and silicone over time. And they leave fumes in the most enclosed room in your house.

The bleach sprays don’t kill mould. They bleach the colour out of it. The black stain goes away, the spores don’t. Two weeks later the mould is back — in the same spot, because it never actually left. You spray again. You hold your breath again.

That’s the cycle. And it’s the cycle because the product was never built to break it.

What if the mould never came back?

Clove oil kills mould at the root. The active compound is eugenol — the same thing dentists use to sterilise. A light spray once a week, left for 20 minutes, kills spores before they can establish. The cycle breaks.

That’s the real product. Not a crisis fix. A weekly maintenance spray that means the mould stops returning in the first place.

Five ingredients. Water, castile soap, methylated spirits to dry the surface, 100% pure eucalyptus oil, 100% pure clove oil. That’s it.

No chlorine. No caustic soda. No holding your breath.

“I have tried a lot of mould products in my life, but this has been one of the best. Very effective, easy to use. Follow the directions and to date the mould has not resurfaced.” ★★★★★ — Melbourne

First, about the label.

The bottle in your hand may say “leave for up to 72 hours.” Ignore that. The formula’s been improved since those labels were printed — 20 minutes is all you actually need. We’re working through existing label stock before reprinting. If your bottle still says 72 hours, 20 minutes is the honest answer.

The weekly spray.

1. Spray lightly onto tiles, grout, silicone, glass, chrome — anywhere mould tends to start.
2. Leave for 20 minutes. Walk away. Make a coffee.
3. Scrub with a non-scratching abrasive sponge.
4. Rinse with warm water.

That’s the maintenance routine. Once a week breaks the cycle.

If you’ve already got mould.

Same process, longer application. Spray directly onto the mould-affected area. Leave 20 minutes. Scrub with a non-scratching abrasive sponge. Rinse. A second application usually handles stubborn spots. On porous grout or old silicone, the mould will be dead — the stain may remain. The cycle will break.

The smell.

Clove oil is sharp. Some people love it immediately, some find it strong at first. That’s not a flaw — it’s the clove actually being clove, not a synthetic fragrance pretending to be clove. Open a window while it’s working. By the time you rinse, the smell has mellowed to something that quietly tells everyone who walks past the bathroom that it’s been properly cleaned.

The bathroom is the obvious one. Shower tiles. Grout. Silicone seals around the bath. The shower screen. The chrome. The fibreglass base. The glass. This is where mould spends most of its time and where you’ll use this product the most.

But mould lives in more places than you think. Window frames — aluminium, timber, vinyl — where condensation pools overnight. The seal between the bath and the wall. The caravan or boat you’re about to pull out for summer. The laundry tiles. Inside the shower screen track where no one looks. Behind the toilet.

If it’s a hard, non-painted surface and it gets damp, this product works there.

What about natural stone?

Fine — as long as it’s sealed and non-porous. This formula is just castile soap, methylated spirits, water and pure clove and eucalyptus oils. No acids, no bleach — nothing that etches marble, travertine or Caesarstone. Test on a small hidden spot first if you’re unsure.

Got painted walls or ceilings?

Different surface, different product. Paint is delicate — this formula can lift it. For painted walls and ceilings, you want our All Natural Mould Remover Wall Cleaner instead.

Easy way to remember it:
Paint = Wall Cleaner. Everything else = this bottle.

Where not to use it:

- Plastic — the clove and eucalyptus oils can stain plastic over time. Don’t leave the product sitting on it.
- Old rubberised shower floors — can stain the rubber.
- Fabric, carpet, blinds — not designed for soft surfaces.
- Painted surfaces — use the Wall Cleaner instead.

If your surface isn’t on either list, test on a small hidden spot first. Five minutes of testing saves a regret.

“Best product on the market for mould removal. I have tried San Air and all the mould removal options from Bunnings — nothing works as good. Super low tox.” ★★★★★ — Pyrmont

We name every ingredient. Not “fragrance.” Not “cleaning agents.” Not “surfactant blend.” Every single thing in this bottle, named and explained — because we have nothing to hide.

Pure Castile Soap — plant-based soap that holds the oils in suspension and lifts the dead mould off the surface after the clove has killed it. Without it, you’d be spraying oil and water onto your tiles and watching it separate.

Methylated Spirits — simply alcohol with a natural bitterant added to stop people drinking it. That’s all. Mould needs moisture to survive; the alcohol pulls the moisture out of the surface, evaporates completely, and leaves nothing behind. Two jobs at once — helping the oils penetrate, and drying the surface so mould can’t come back.

100% Pure Eucalyptus Oil — Australian-grown. Supports the clove, cuts through the residue, and carries that sharp, clean scent that tells you something is actually working.

100% Pure Clove Oil — the active ingredient doing the real work. The compound inside clove is called eugenol — the same thing dentists use to sterilise. It kills mould on contact.

Water — the base that carries the formula onto the surface. Nothing synthetic added.

No bleach. No chlorine. No caustic soda. No synthetic fragrance. No dyes.

Most mould sprays don’t even tell you what’s in them — and when they do, it’s sodium hypochlorite and a list of ingredients you’d rather not google. We list everything because we have nothing to hide.

“Over the years I’ve been slowly trying to eliminate toxic products in my home but haven’t been satisfied with what’s on the market, until now. My favourite product is the Clove & Eucalyptus Mould Spray. I’m so glad I never have to use bleach again.” ★★★★★ — Ferntree Gully

I’ve tried three other mould sprays and nothing worked. Will this?
Honest answer: probably. Bleach sprays don’t actually kill mould — they bleach the colour out of it, so the spores stay and the mould comes back. Clove oil kills the spores at the root. Most customers who say “I’ve tried everything” find this is the first product where the mould doesn’t come back.

Will my silicone go white again?
Probably not — and this is important. Silicone is porous. Mould grows deep into the material, not just on top. This spray will kill the mould, so it stops spreading and stops coming back. But the black stain may remain, especially on old silicone. If your silicone is badly stained after treatment, the honest answer is it may need to be cut out and replaced.

What about grout?
Same rule. Grout is porous. The spray kills the mould at the root, but deeply ingrained stains on old grout may remain. Regular weekly use stops new mould establishing in the first place — which is the real solution on grout.

Why does the bottle say 72 hours but the website says 20?
The formula’s been improved since those labels were printed. 20 minutes is all you need. We’re working through existing label stock before reprinting. If your bottle still says 72 hours, trust the website.

Will it stop mould coming back?
Yes — if you use it weekly. A light preventative spray once a week, left for 20 minutes and rinsed, kills spores before they can take hold. This is the single biggest shift customers report: mould stops being something they deal with every few months and becomes something they stop before it starts.

Two mould sprays on your site. Which one do I need?
Paint = Wall Cleaner. Everything else = this bottle. This Clove & Eucalyptus Mould Spray is for tiles, grout, silicone, glass, chrome, shower screens, window frames, caravans — anything hard and non-painted. Our All Natural Mould Remover Wall Cleaner is for painted walls and ceilings. They’re opposite products for opposite surfaces.

Is it safe around kids and pets?
Yes. No bleach, no chlorine, no caustic chemicals. The clove and eucalyptus oils are powerful natural compounds, so open a window or run the exhaust fan while the product is working. If you’re still worried, just close the door on the bathroom for a while — no need to evacuate the house the way you do with bleach-based sprays.

The bigger issue with most cleaners isn’t the cleaning — it’s what stays behind. Synthetic fragrance is designed to cling to surfaces long after you’ve rinsed. That’s the chemical film your kids crawl on and your pets walk through for days afterwards. Pure essential oils evaporate cleanly and leave nothing behind. Once the clove and eucalyptus have done their job, they’re gone.

The smell is strong. Is that normal?
Yes. Clove is a sharp, intense scent — that’s pure clove oil, not a synthetic version. Some people love it immediately, some find it strong at first and get used to it. What you’re smelling is the clove actually doing its job. If a cleaner smells like nothing, it probably isn’t doing much.

Is it safe for septic systems?
Yes. No bleach, no harsh chemicals. Safe for septic tanks and grey water.

What if I don’t like it?
We offer a lifetime money-back guarantee — no return required, no questions asked, no expiry. If it’s not right for you, we’ll refund you in full.

The Australian Eucalyptus Oil Company has been making eucalyptus products since 1895. Five generations. Over 130 years. This mould spray is made the same way we’ve always made things — with 100% transparency.

If you’re not completely happy, we’ll refund you in full. No return required. No questions asked. No expiry on that promise.
