HG Mould 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!

I'm absolutely thrilled with HG Mould Spray! It's honestly one of the best mould and mildew cleaners I've ever used.I had a particularly stubborn mould problem in my bathroom, especially on the silicone sealant around the bath and in the corners of the shower. I tried a few other products, but they didn't really do the trick. Then I decided to give HG Mould Spray a go, and I'm so glad I did.Here's what I loved about it:Highly Effective: It worked like magic! The mould started to disappear within minutes of spraying. I left it on for the recommended time, and when I came back, the surfaces looked brand new.Easy to Use: The spray is very easy to apply, and it gets into all those awkward corners and edges. No scrubbing or hard work is required!Versatile: I've used it on various surfaces, including tiles, silicone, and grout, and it has worked wonders on all of them.Fast-Acting: It works much faster than other mould cleaners I've used.Overall, I'm extremely impressed with HG Mould Spray. It's a powerful and effective solution for removing mould and mildew, and it has made my bathroom look clean and fresh again. I would highly recommend it to anyone struggling with stubborn mould problems.

Great product. Had small amounts of mould around the window. Sprayed on the item and left for 30 mins removed all of the mould. Downside is that the product stinks. Make sure you air the room.

I don’t know what mould removal was before this great piece of art. I no longer have to waste time scrubbing after spraying mould spray and enduring the smell. Don’t get me wrong it is very strong but I can spray leave. Come back to complete removal of mould. I would buy this 10 times over super functional. It’s obviously clear in colour and great value for money. Mould slobs right off honestly don’t waste any time on using anything else. Just buy this.

Vary good on wall, wood and other material. It does remove the mould in less than few minutes.Strong odour, so keep the room ventilated

I never leave reviews, but this product actually saved me hours worth of time. Instead of hours physically cleaning, I sprayed it, then left the room ventilated, came back, it had cleaned practically everything. A few areas needed a second spray, but it works wonders, just vent it, and it's the easiest job you'll have to do. A few sprays, come back, wipe it down, job done. Love it, gonna use this in future when needed to get rid of black mold

Best mould remover I've ever used, it certainly does the job very well. Sprayed around my mouldy bath area and next morning it was all gone and now looks like new..

The product does the job well, but it damaged the wall and the paint has now cracked and chipped from the ceiling. The bleach smell was so strong that even after opening all the windows and doors in the room/house took hours to get rid off.
