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

This HG Mould Spray is a 5/5 gem item. I used it on stubborn black mould in the bathroom and it actually works — kills mould fast and makes surfaces look clean again. Just spray, wait a bit, and the mould loosens right off. ✔️ Super effective at removing mould ✔️ Easy to use — just spray and wipe ✔️ Works on tiles, grout, silicone and other surfaces ✔️ Strong results without hours of scrubbing Highly recommend if you need real mould removal — this one does the job properly!

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.

Really effective, best product I have tried. Just need to ventilate well while using, but will be buying again.

Amazing stuff Thank you hg for something that actually works. It lasted around five weeks until tiny signs of it coming back but it was amazing on ceiling rubber seals windows. Would definitely recommend this but make sure you spray it and leave it and ventilation is a must as very strong vapour

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.

This is my second purchase. I find this product amazingly effective in removing black mould from all sorts of places. So easy to just give it a spray, leave for about 20 mins or so and wipe it off. One thing to note is the very strong bleachy smell - so open your windows and perhaps do it while the kids are in school. It has been a gamechanger in the kitchen and bathroom. Especially shower.

It's rare that I'll leave a review but thought this deserves one! We live in a rented house and the kitchen and bathroom are in a cold extension. No matter how much we have the heating on, open the windows, wipe down with bleach etc it is always a battle at this time of year 😕 I read the reviews and decided that this was worth a try at a reasonable price. I was sceptical and when first sprayed on thought there was little chance of it actually working. Half an hour later there was some improvement so I sprayed again and left it to do its magic. The result after that was pretty good! Not 100% perfect but it had its work cut out so I'm very pleased and will continue to use it 😊 Please see before and after photos

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
