HGMould Spray, Effective Mould Spray & Mildew Cleaner, Removes Mouldy Stains From Walls, Tiles, Silicone Seals & More - 500ml , Pack of 1

A Game-Changer for Tackling Mould—Highly Effective!Having tried countless mould sprays over the years, this is the only one that has truly delivered exceptional results. It’s incredibly effective and has saved me time, money, and effort in both my home and work life.I’ve used this spray on silicone sealant that I thought would require expensive replacement due to dark black mould spots. To my surprise, just a couple of applications completely eradicated the mould! For very deep, dark, or large areas of mould that have penetrated the sealant, multiple applications may be necessary, but even then, the mould fades significantly.This product works wonders not just on bathroom and kitchen sealants but also on discoloured grout, window frames and seals, skirting boards, backs of furniture (with care—always test a small area first and avoid soaking expensive or varnished items), and bathroom/shower walls and ceilings. While it’s not officially recommended for painted surfaces, I’ve successfully used it on white emulsion-painted areas without any issues—no scrubbing required! I typically spray generously and leave it overnight for best results. For tougher mould spots, a second or third application might be needed.The spray does have a strong chemical odour similar to bleach, so proper precautions are essential. I recommend wearing a mask and goggles (especially if spraying higher areas like ceilings) and ensuring the room is well-ventilated by opening windows. With common-sense safety measures in place, it’s easy to use effectively.As someone who works in property management and deals with over 20 properties annually that have condensation-related mould issues, this product has been a lifesaver. It allows me to resolve mould problems quickly and efficiently. We also use it routinely between tenancies to clean bathrooms—grout, sealant, and ceilings—saving significant time compared to scrubbing grout with bleach or replacing sealant altogether.In my own home, I used to replace the shower sealant every 12–18 months due to mould buildup. Since using this spray, the sealant looks like new and stays fresh for years! Regularly spraying as soon as mould spots appear prevents the need for multiple applications and makes one bottle last an impressively long time.I’ve only deducted one star for minor reasons: the product takes several hours to work its magic (so patience is required), multiple applications may be needed for severe mould cases, and the odour can be quite strong when working with large areas. Additionally, while the safety catch above the trigger is a bit fiddly, it’s an essential feature for child safety. The internal tube now needs inserting before first use—it’s slightly inconvenient but helps prevent damage from long-term chemical exposure if stored unused for extended periods.Overall, this product is nothing short of amazing. It’s transformed how I deal with mould at home and in my work. If you’re looking for an effective solution to tackle stubborn mould problems without breaking the bank or spending hours scrubbing, I highly recommend giving this a try!

Let me set the scene: my shower ceiling looked like it was hosting a black mold renaissance. I half expected to hear Gregorian chants every time I stepped in. The mildew had claimed the tiles as its homeland. I considered just moving out and letting it keep the place.Enter: HG Mould Spray, also known as “the stuff that made my bathroom stop looking like a horror film set.”With one heroic spray (okay, eight or nine if I’m honest), the mold hissed, recoiled, and vanished like a vampire at sunrise. This stuff doesn’t mess around—it’s like bleach had a baby with a flamethrower and sent it to cleaning school.Pros:✅ Obliterates mold like it's got a personal vendetta✅ Works fast—you’ll see results before you can say “fungus be gone”✅ Satisfying enough to make you want to clean on purposeCons:⚠️ Smells like it could melt a nostril or two.

Did not help.Final Verdict:If you’ve got mold, mildew, or a bathroom that looks like a haunted house, HG Mould Spray is your new best friend. Just don’t inhale deeply or grow too attached to the grout—it’s about to have a personality change.10/10, would wage chemical war on mold again.

This mould spray has treated the mould on my bath silicone better than most other household cleaning solutions. I’ve removed a star simply because you have to treat the area several times, so does use quite a bit of product on for one job.

We had very bad black mould in our shower. The shower is in the basement with no window but there is an extractor fan.Over a period of months the black mould has got worse despite trying to clean it off with a scrubber, only bits came off.So I bought the HG spray for £4.50 for a punt.First off, you need to remove a part of the bottle to open it, it's not the part in the image, it's the clear plastic bump between the neck and the trigger, check YouTube for a good video, then twist the tab 90 degrees and you can start spraying.I ended up using the whole bottle over 4 attempts as it was so bad, but each attempt was better and better.It now has mould stains but I'd say it has removed a good 90% of the black mould and I'm happy with that.Now we have something to work with on a cleaning schedule with less harsher chemicals.I agree it is a strong smell, but it didn't linger for long, especially with the extractor fan on.For the price, even using the full bottle was money well spent.I'd expect if ours was less established it would have worked even better.Very happy with my purchase.

Hag a leak from the balcony of the above me and blackspot appearing on 2 walls about a meter square. Got the source of the leak sorted and fully dried for couple months. Time to clean up. Thick rubber gloves, face mask and goggles/glasses are a must plus old clothes. This stuff is potent. Get the windows open. Lay down plenty of newspaper to cover floor/carpet. Tape it to the skirting.Spray gently from the top down, not overdoing it. You don't need to soak the area. Immediately, the black spot starts running down the wall. 30 mins later, I would not even know that I'd had a blackspot problem. Rinse gently with clean water/sponge/bucket. Let it dry for a few hours b4 painting. To be honest, I didn't even need to re-paint but I did anyway. The wall looked fresh. And I mean FRESH.
