HG Mould Remover Spray | Kills Black Mold & Mildew on Walls & Tiles | 500ml

My flabbers are ghasted. This product works so well for mould I cannot believe it! Really simple to use, no scrubbing needed, just a quick wipe. The other reviewers are correct that it is very smelly, but clears with an open window.

I was a little skeptical about this product as I have used other mould removers in the past and they require a hefty bit of elbow grease in addition to their mould removing properties... I followed the instructions, sprayed on the affected area (my bath silicone sealant in this case) and left it.. I set a 30 minute timer on my phone and went into the garden. After the 30 minutes had gone by, the first thing I noticed was the strong smell of bleach. Not over powering, but a strong smell nonetheless (keep your windows open). I was AMAZED by the results... 30 minutes on, just wiped away. It was super easy to use! There was only 1 area that needed a second spray, but honestly, the end results were great! For the price, I would definitely recommend this bad boy! We all look at the mould in our bathroom and think, I'll get round to it at some point... Order this now and thank me later, absolute game changer. But like I said, just make sure you keep that window open because it's a strong smell.

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.

We don’t have a window in our bathroom and the extractor fan isn’t great, so we get quite a bit of moisture build up and therefore a recurring mould issue. We had mould all the way round the bath sealant, on the tiles next to the shower and on the ceiling above the shower to the point where I thought we were going to have to replace the sealant and repaint the ceiling. I applied the mould spray all over the affected areas and I could see it starting to work after only a few minutes. After 30 minutes all the mould had completely gone with no need to wipe, I just used the shower head to give some of the areas a rinse down and that was it. It’s very impressive stuff to a dullster like me. It hadn’t just masked over the mould, it had actually eaten away at it. It will be interesting to see how quickly the mould returns if at all. One thing I will say though is that it absolutely stinks of chlorine and I’m glad I chose to use it on a day that my daughter was at nursery. The smell is horrible and can be quite overwhelming. I was wearing a pair of gloves as instructed and a full face mask (the kind you would wear if you were spray painting a car) and I could still smell it. Even with all the upstairs windows and doors wide open you could still smell it for hours after and it even lingered into the next day. It actually left me feeling quite short of breath at points and I had to leave the house, so if you have a breathing condition or are quite sensitive to smells then I do not recommend this stuff to you. If you have a baby or young children I would make sure that they are out of the house while you use this or at the very least a different floor to the one you’re using it.

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 product is not only good for mould but as a cleaning agent too, just spray on shower tiles or glass or any other surface obvs hard areas not furniture, leave for half hour rinse then WALLA!! Perfect results, use in toilets then just flush, on your worktops just wipe off, easy as that, my favorite cleaner, better than any bleach even though its a bleaching substance, beware of very potent smell, leave windows open.

Our ensuite has a fan but we were developing black spots on the ceiling and a wall which were growing. Lightly sprayed affected areas or dabbed cotton wool soaked in liquid and spots disappeared in less than a day. Also had black mold growing around sealant in the shower and this got rid of that too. It does smell VERY strongly but that goes away within a week.

What an amazing product. Does exactly as described and more..made deep cleaning widows and panels in conservatory easy . Not only rids you of mould from condensation makes the pvc frames immaculate . Best product on the market great price highly reccomend
