HG Mould Spray - Effective Black Mould & Mildew Cleaner, Removes Stains – 500ml

I’m genuinely impressed with the HG Mould Spray. It does exactly what it promises and works incredibly fast. I used it on stubborn black mould and mildew in my bathroom (around the shower seals and tiles), and the results were visible within minutes. The stains lifted without any heavy scrubbing, leaving the surfaces looking clean and fresh again. The spray is easy to apply, clings well to vertical surfaces, and covers a good area. A little goes a long way, so the 500ml bottle feels great value for money. While the smell is strong (as expected for a powerful mould cleaner), it clears quickly with ventilation and is absolutely worth it for how effective the product is. What I really like is that it doesn’t just mask the problem — it actually removes deep-set mould stains and restores surfaces to their original appearance. Perfect for bathrooms, kitchens, and any damp areas. Highly recommended if you’re dealing with mould or mildew and want a reliable, professional-level cleaner that actually works. I will definitely be buying this again.

I was initially skeptical after reading some of the negative reviews, but this HG Mould Spray truly amazed me. I had visible mould patches on an internal wall near the skirting board, and after spraying it and leaving it to work, the mould started disappearing without the need for heavy scrubbing. The difference was honestly “before and after” level. It’s very easy to use, effective, and saves a lot of effort compared to other products I’ve tried. Just make sure the room is well ventilated while using it, as the smell is quite strong (as expected with mould removers). Overall, I’m extremely happy with the result and would definitely buy it again. Highly recommended!

I recently used the HG Mould Spray (500 ml) and it genuinely exceeded my expectations — for context, I’m an accountant by day, creator by night, so I know the value of something that works efficiently and cleanly. What worked well: • The spray formula really pulled mould and mildew out of grout lines, seals and bathroom corners where it had been creeping in. No endless scrubbing. • One application restored the surface so it looked fresh again — the whitish-background tiles looked uniform, the stains were fading. • The 500 ml size is generous; I had enough for the shower area, skirting board and a window-frame seal and still had some left. • The product is reliable: it’s from a well-known cleaning brand, and the specs clearly list use on tiles, grout, plastered walls, outdoor furniture and more. What to keep in mind: • The smell is strong — it has a bleach-type odour, so good ventilation is essential. Some users commented it could linger. • After spraying you’ll need to rinse or wipe the area; it’s not a ‘spray and forget’ for very heavy infestations. Some very deep mould spots may need a second treatment. • As always with potent cleaners, gloves and protective measures are recommended (especially on sensitive surfaces) — the manufacturer’s instructions emphasise safety. Overall verdict: If you’re dealing with persistent mould or mildew — especially in damp areas like bathrooms or around windows — this product is a smart investment. It delivered fast, visible results with minimal effort. If your priority is something reliable and effective (rather than low scent or ultra-eco gentle), this hits the mark.

Brilliant stuff. Works in minutes, just spray on. Ventilate the room though. Its got a very strong bleach smell and will burn your eyes.

I used this on black mould that had built up around the silicone and grout in our bathroom, particularly in areas affected by condensation. I sprayed it on as directed and left it to work, and the results were excellent! the mould visibly faded and then cleared with very little effort. In areas where the mould was heavier, I needed to repeat the process, but it still worked well and saved me from having to replace the silicone. It does have a strong smell, so good ventilation and gloves are a must, but that’s expected with a product this effective. Once the mould was fully removed and everything was clean and dry, I followed up with a mould prevention spray to help stop it coming back. Using the two together feels like a much more long-term solution rather than just treating the surface. Overall, this is a very effective mould remover especially when used properly and followed by a preventative treatment. Definitely worth having on hand for stubborn bathroom mould.

I'm not much of a reviewer, but credit where it's due this product is awesome We normally leave the bathroom window open to air the room out and help it dry, but with the colder weather of the last few weeks it's been closed, and several patches of mould have absolutely run wild, In the past I have kept them at bay with scrubbing with bleach and other cleaning products, but it never gets rid of the marks left behind fully I decided time to bite the bullet and get an actual mould cleaner and deal with it properly I was totally sceptical of the claims of simply spray it on and walk away, how on earth would that get rid of a horrible black patch on the ceiling But it works and it works extremely fast, The product says to leave it on for 30 minutes, but for me within 5 it was totally clean People have mentioned the smell, to me it mostly is a bleach type smell so no different to giving the bathroom a scrub anyway, it is potentially though and as you're spraying it on it does get a bit airborne so your eyes may sting a bit, I'd recommend keeping children and animals well clear while you're spraying and close the door after if possible The size of the bottle gives a lot of coverage, I heavily covered my whole bathroom, and all of the areas where it normally creeps in over winter, such as upstairs window frames, and I still have over half a bottle left Amazing product 10/10 will buy again if I need to without hesitation

This is NOT the spray! This is the foam version which is NOT as effective as the spray. I ordered 3 times in total. The first one was the spray. The second was the foam version. I thought this was a mistake so I ordered a third one and it's also the foam.

We used a whole bottle for our basement, we spayed the wall and after 5 mins, the wall became white immediately, better than we expected. Good product but smell bad like bleach. We used the whole bottle for the wall and it cost us about 14 dollars it is a little bit expensive and we have to buy again. over all it is good and highly recommended.

Does wonders for stubborn water stains and molds in shower area

Da qualche anno lo acquistavo in Inghilterra, ora finalmente è disponibile su Amazon.it, basta spruzzare sulle zone interessate e rimuove la muffa anche più ostinata in pochi minuti.

Risultato incredibile, ha rimosso dalla doccia ogni macchia di muffa anche le più ostinate, comprese le fughe. Prodotto consigliatissimo. Ottimo
