Mould and mildew aren’t just unsightly — they can cause real damage to your home and health if left untreated. From black patches on bathroom grout to orange mildew on silicone seals, this ranking covers the most effective mould removers you can buy in the UK this year.
What Are Mould & Mildew Removers?
Mould and mildew removers are targeted cleaning products designed to eliminate fungal growths on household surfaces. Most contain strong active ingredients like bleach, sodium hypochlorite, or fungicides to break down and lift visible mould — and in some cases kill spores beneath the surface. They’re commonly used in bathrooms, kitchens, window frames, and damp-prone areas

Verdict: Strength Comes at a Cost — But Some Strike the Perfect Balance
With over 100,000 verified UK reviews across this category, these mould and mildew removers are some of the most tested cleaning products on the market — and the top-ranked entries all deliver results.
HG’s Foam and Spray formulas, along with RMR’s powerful remover, have each been battle-tested in thousands of homes and still hold impressively high ratings. But with great strength comes some compromise: many of these formulas are harsh, heavy-duty, and not exactly pleasant to use in a small domestic setting. That shows up in their User Experience scores, where some products lost points for fumes, packaging design, or general harshness.
At the other end of the spectrum, cheaper options often require a separate spray bottle or don’t quite have the same instant punch — though they can still be a great value if you’re tackling mould in smaller patches.
Cillit Bang Black Mould Remover stands out as the most balanced option for most households. It’s potent, budget-friendly, and easy to apply in a standard spray format — making it ideal for regular use in bathrooms and kitchens.
By contrast, formulas like RMR and Dryzone feel better suited to contractors or homes in more serious disrepair. They cover large areas quickly and work on multiple surfaces, but come at a higher cost and with a much heavier chemical footprint.
❓ FAQs
Can I use these mould removers on any surface?
Most products in this list are safe for tiles, grout, and bathroom surfaces, but not all are suitable for painted walls, wood, or fabrics. Always check the label before use — and test on a small hidden area first if you’re unsure. For silicone seals and shower edges, foaming formulas like HG Foam often give the best cling and contact time.
Do I need to rinse off mould remover after use?
Yes — for most of these products, rinsing or wiping down the area after application is recommended, especially in food-prep or pet-accessible areas. Some formulas contain strong biocides or bleaches that should not be left to dry on the surface. Always follow the usage instructions for safety and best results.
