What you'll need
Always ventilate the bathroom when using bleach or strong chemical cleaners. Never mix cleaning products.
Step-by-step guide
- Apply products and leave to workDon't start scrubbing immediately. Apply limescale remover to the toilet bowl, shower screen, taps, and showerhead. Apply mould spray to any affected grout and silicone seals. Leave for the time specified on the product — usually 10-20 minutes. This is when the chemistry does the work.
- Tackle the toiletScrub the bowl thoroughly with a toilet brush, paying attention to under the rim. Use an old cloth or disposable wipe to clean the outside of the bowl, the base, and behind the cistern — the most neglected areas.
- Clean the shower screen and tapsUse a non-scratch sponge to remove loosened limescale from the screen. Rinse thoroughly. For taps, wrap tissue soaked in limescale remover around them and leave for 30 minutes for heavy buildup.
- Clean the groutUse an old toothbrush with grout cleaner or a bleach solution on discoloured grout. Work in sections and rinse. For black mould in silicone, apply neat bleach gel and leave for an hour.
- Clean surfaces and mirrorsWipe all surfaces — shelves, windowsill, top of toilet cistern. Glass cleaner or diluted white vinegar on mirrors gives a streak-free result.
- Mop the floorMove everything possible off the floor. Mop with a disinfectant floor cleaner, getting into corners and behind the toilet.
Clean from top to bottom and from back to front — you're moving dust and droplets towards the door and floor throughout the clean.
Expert tips for the best result
- Never mix bleach with other cleaning products — especially vinegar or ammonia-based cleaners
- Silicone seal that's permanently black with mould should be cut out and replaced — no cleaner reverses deep mould
- A weekly spray of daily shower spray on the screen and walls prevents 90% of limescale buildup
- Mould in grout is often a ventilation problem — a humidity-controlled extractor fan prevents it recurring
- Bar of soap leaves more residue than shower gel — switching reduces weekly cleaning time significantly
