Bathroom Glow-Up: How to Deep Clean Your Bathroom This Winter (And Actually Keep It That Way)

Okay, real talk — your bathroom has been through it. Between the steamy winter showers, the condensation that just won't quit, and the grout that's slowly turning a shade of grey you did not choose, your bathroom is basically screaming for a glow-up. And honestly? Same.

Winter is peak mould season in Australian homes. The combination of cold air, hot showers, and poor ventilation creates the perfect storm for mildew, soap scum build-up, and that musty smell that no amount of air freshener can fix. But here's the thing — a proper deep clean doesn't have to take your whole Saturday. With the right products and a solid game plan, you can have your bathroom looking chef's kiss in under an hour.

We're breaking it down room by room (well, zone by zone — it's a bathroom, not a mansion) so you can tackle it like a pro. Let's get into it.

Why Winter Is the Worst for Bathrooms (And What to Do About It)

Here's the science bit, but make it quick: mould and mildew thrive in warm, humid environments. Every time you take a hot shower in winter and don't ventilate properly, you're basically rolling out the welcome mat for mould spores. They love tile grout, silicone seals, shower curtains, and the corners of your ceiling — basically everywhere you don't want them.

The fix? A deep clean to reset the space, followed by a simple maintenance routine that takes less than five minutes a day. We've got you covered on both fronts.

What You'll Need: Your Winter Bathroom Glow-Up Kit

Before you start, grab these heroes:

• Astonish Mould Blast Stain Remover — the absolute MVP for tackling mould and mildew on tiles, grout, and silicone seals
• Astonish Bathroom Cleaner — a powerhouse for soap scum, limescale, and general grime on sinks, taps, and shower screens
• Fabulosa Concentrated Antibacterial Disinfectant — because your bathroom deserves to smell incredible while it gets sanitised
• A microfibre cloth (or two — one for scrubbing, one for buffing)
• An old toothbrush for grout lines
• Rubber gloves (non-negotiable, bestie)
• A squeegee for the shower screen

Step-by-Step: The Ultimate Winter Bathroom Deep Clean

Step 1: Declutter and Prep (5 minutes)

Clear everything off your surfaces — products, soap dishes, toothbrush holders, all of it. This is your reset moment. Wipe down any bottles before putting them back (you'd be surprised how grimy the bottom of a shampoo bottle gets). Pop your bath mat in the wash while you're at it.

Step 2: Attack the Mould First (10 minutes)

This is the step most people skip — and it's the most important one. Spray Astonish Mould Blast directly onto any mouldy grout lines, silicone seals, and tile corners. Let it sit for at least 5 minutes (longer for stubborn spots — up to 10 minutes). The formula is designed to penetrate and lift mould stains without you having to scrub your arm off.

While it's doing its thing, use an old toothbrush to work the product into grout lines. Rinse thoroughly with warm water. You'll be genuinely shocked at the difference.

Pro tip: Do this step with the exhaust fan running and the window open if you can. Ventilation is your best friend.

Step 3: Shower Screen and Tiles (10 minutes)

Soap scum on a shower screen is basically the villain of every bathroom glow-up story. Spray Astonish Bathroom Cleaner generously over the screen and tiles, leave for 2–3 minutes, then wipe down with a damp microfibre cloth using circular motions. For stubborn limescale around taps and shower heads, apply the product and let it sit a little longer before wiping.

Finish with a squeegee on the shower screen for that satisfying streak-free result. This is the part that looks so good on a clean-with-me video, just saying.

Step 4: Toilet Deep Clean (5 minutes)

Don't skip the toilet — and don't just do the bowl. The base, the cistern, the hinges, and the seat all need attention. Spray Fabulosa Antibacterial Disinfectant over the entire exterior of the toilet, leave for a minute, then wipe down with a cloth. The antibacterial formula kills 99.9% of bacteria while leaving your bathroom smelling absolutely divine — not like a hospital, not like a chemical factory, but genuinely good.

For the bowl, use your toilet brush with a squirt of Fabulosa and give it a thorough scrub under the rim and around the bowl. Flush and done.

Step 5: Sink, Vanity, and Taps (5 minutes)

Spray Astonish Bathroom Cleaner around the sink basin, taps, and vanity surface. Wipe down with a microfibre cloth, paying extra attention to the area around the tap base where toothpaste and soap residue love to hide. Buff the taps dry with a clean cloth for a streak-free shine — this small step makes a huge difference to how polished the whole space looks.

Step 6: Floors (5 minutes)

Mix a capful of Fabulosa Concentrated Disinfectant with warm water in a bucket and mop your bathroom floor. The concentrated formula means a little goes a long way, and the scent lingers beautifully — your bathroom will smell like a day spa, not a cleaning session.

Don't forget to wipe the skirting boards and the base of the toilet while you're down there. Future you will thank present you.

Step 7: The Finishing Touch (2 minutes)

Replace your freshly washed bath mat, put your products back neatly, and take a moment to actually appreciate what you've just done. Seriously — stand in the doorway and look at it. That's your work. That's your glow-up.

How to Keep Your Bathroom Clean All Winter (Without Losing Your Mind)

A deep clean is great, but the real flex is maintaining it. Here's a simple daily and weekly routine that takes almost no time:

Daily (2 minutes):

• Run the exhaust fan for at least 15 minutes after every shower
• Give the shower screen a quick squeegee after use
• Wipe down the sink after brushing teeth

Weekly (10 minutes):

• Spray and wipe tiles and shower screen with Astonish Bathroom Cleaner
• Disinfect the toilet with Fabulosa
• Mop the floor with diluted Fabulosa Concentrated Disinfectant
• Check grout lines for any early mould signs and spot-treat with Astonish Mould Blast

This routine takes less time than scrolling TikTok for 10 minutes — and the results are way more satisfying (no offence to TikTok).
