A bathroom that looks clean on the surface can still harbour mould, limescale, and bacteria in the grout lines, under the toilet rim, and behind the fixtures. The HGTV video above shows the process in real time — this article breaks it down into a clear, repeatable routine you can follow for a home, a holiday rental, or a hotel room in Greece. Follow the steps in order so you are never spreading dirt back onto surfaces you have already cleaned.
Why a Deep Clean Is Different from a Weekly Wipe-Down
A regular clean deals with visible dirt: a quick spray of the mirror, a swipe of the sink, a toilet brush pass. A deep clean goes further — it removes built-up limescale from shower heads and taps, breaks down soap scum on tile grout, descales the toilet trap, and disinfects the drains. In Greece, hard water is common across most of the mainland and islands, so limescale accumulates faster than in northern Europe. Factoring a proper deep clean into your monthly or quarterly schedule prevents staining that becomes very difficult to reverse.
For holiday rental owners and hotel managers, a deep clean is also a commercial obligation. Guest reviews frequently mention bathroom hygiene above any other room, and a single negative comment about mould or limescale staining can cost multiple future bookings.
Gather Your Supplies Before You Start
Having everything in reach before you begin means you finish faster and do not cross-contaminate surfaces by walking in and out. You will need: a spray bottle of all-purpose bathroom cleaner, a dedicated limescale remover (citric-acid or phosphoric-acid based), bleach or a mould-and-mildew spray, a grout brush, a non-scratch scouring pad, microfibre cloths (at least three, colour-coded by zone), a toilet brush, rubber gloves, and a bucket and mop for the floor. In Greece you can buy all of these at any large supermarket or a Leroy Merlin store.
How to Deep Clean a Bathroom: 5 Steps
- 1
Apply products and let them soak
Before scrubbing anything, apply your cleaners so they have time to work. Spray limescale remover on the shower head, taps, and the inside of the toilet bowl. Apply mould spray to grout lines and the bottom edges of the shower tray or bathtub. Let everything soak for at least ten minutes — for heavy limescale, fifteen to twenty minutes. Starting products while you do other tasks is the single biggest time-saver in a bathroom deep clean.

Clean mirrors, glass, and high surfaces first
Work from top to bottom so drips fall on dirty surfaces rather than clean ones. Wipe the light fitting and any shelving with a dry microfibre cloth. Then clean the mirror: mist it lightly with glass cleaner or a 50/50 water-and-white-vinegar solution, and buff with a clean, lint-free cloth using horizontal strokes. If you have a glass shower enclosure, clean the inside face now using the same method, adding a non-scratch pad for any water-mark build-up at the base.

Scrub tiles, grout, and the shower or bathtub
Use your grout brush to work along every grout line, then rinse with a shower head or a wet cloth. For tiles, a non-scratch scouring pad with a citric-acid spray removes soap scum without dulling the surface. Pay close attention to the silicone bead around the base of the shower tray — if it has gone black, a bleach gel applied with an old toothbrush and left for ten minutes will lift most staining. Rinse everything thoroughly and check for any loose or crumbling grout that needs re-sealing.

Deep clean the toilet inside and out
The limescale remover you applied in Step 1 should now have softened any staining under the rim and in the trap. Scrub the bowl with a toilet brush, pushing the brush well under the rim where bacteria collect. For stubborn limescale rings, a pumice stone dipped in water is safe on porcelain and very effective. Then work outward: clean the top of the tank, the handle, the hinges, and — most importantly — the base of the toilet and the floor around it, which accumulates grime that weekly cleans miss.
- 5
Rinse, mop the floor, and ventilate
Remove any remaining product from tiles, the bathtub, and fixtures by rinsing with clean water. Decant dirty water, then mop the floor from the far corner toward the door so you are never stepping on a wet, just-cleaned surface. After mopping, leave the bathroom door open and the extractor fan or window running for at least thirty minutes. In Greek summer heat, surfaces dry quickly; in winter or in bathrooms without windows, ventilation is critical to prevent the mould returning within days.

FAQ
- How often should I deep clean my bathroom?
- For a primary residence, once a month is the minimum — Greek hard water means limescale builds up quickly on taps and shower heads. Holiday rentals should receive a full deep clean between every change of guests for longer stays, and at least weekly during peak season when turnover is rapid.
- What is the best way to remove black mould from bathroom grout?
- Apply a bleach-based mould and mildew spray directly to the affected grout lines and leave it for ten to fifteen minutes before scrubbing with a stiff grout brush. Rinse thoroughly. For recurring mould, the underlying problem is usually poor ventilation: install or upgrade an extractor fan rated for the bathroom's volume (at minimum 15 air changes per hour is the standard recommendation).
- Can I use vinegar and bleach together to clean the bathroom?
- No — never mix white vinegar (or any acid) with bleach. The combination releases chlorine gas, which is toxic. Use them separately: vinegar is excellent for dissolving limescale on tiles and glass; bleach is effective for disinfecting and killing mould. Rinse a surface completely and allow it to dry before switching from one product to the other.
