    Wish I had taken a before photo. It was black with mould. Waited 30 minutes expecting to have to scrub it and this was the result. No scrubbing required highly recommended

    5.0 out of 5 stars It’s clea

    Used this on a bit of mould around the corner of my window and it killed it clearing it back to the magnolia paint. I then used it on the shower mastic and it killed the mould there as well. Defo works.

    It really does work.
    A couple of things to note: You do need the room to be well ventilated and if you are treating a wall and do not intend to paint it watch out for streaks.

    Great product and it’s lifted all the black mould around my bath and tiles.

    Do wear gloves to protect your skin and ensure area of use is well ventilated.

    It does say this on the bottle and should be followed.

    It’s actually insane how well this works. I didn’t even have to scrub it. I sprayed, went away for 10 minutes, went back and it was pretty much gone. For some spots I had to do it twice, but it was super easy. 10/10

    Bought this product as iv used lots of different things to try and get rid of the mould/damp on my bathroom ceiling nothing has really worked until I used this. Sprayed it and after 5 minutes could already see the results, very strong smelling so make sure to vent the room

    Move over, evil black mould! This spray doesn’t just remove you, it banishes you to the depths of Mouldywood! It’s like wielding a magic wand against the dark forces of mildew. 100% effective? More like 100% wizardry. My bathroom is now a realm of sparkling cleanliness, where mould fears to tread. Five stars, two thumbs up, and a standing ovation for this mould-busting miracle!

    Golden Review Award: 2 From Our UsersI’ve used a lot of concoctions to tackle mould but this spray was a new great find having read the reviews I went ahead and tried it for myself.

    [Check out before & after pics!!]

    Mould was growing inbetween tiles due to bathroom being in an extension so tends to get a lot of moisture.

    I sprayed it on and forgot about it for a few hours and came back to see the mould either completely gone or drastically reduced!!

    Magic in a bottle but very very strong.
    Ended up using the whole bottle without realising. Worth it in my opinion as mould has not come back since.
    Did not need to do any scrubbing – at all!!

    Be warned:
    Please wear gloves, wear face mask, protect your eyes and avoid breathing in the fumes as much as possible. Leave windows open when applying and airing and keep children away.

    It’s a great product and highly recommend! Used on washing machine seal too where there was heavy mould and removed and cleaned after 1 hour of sitting in the seal and all the mould gone!

    It has been 3 months since the pictures taken and spray used – and nothing has come back.

    5.0 out of 5 stars Best mould spray! Tried and Tested! See pics.

    Purchased to deal with mould in the corners of white a bathroom, prior to repainting. After spraying with this, the repaint job wasn’t necessary.
    Also got rid of mould growth on the grout and silicone, but this needs a respray about once a fortnight to keep it white.
    The chlorine smell is very strong, so ventilate the area well.
    Will definitely buy again.

    Golden Review Award: 3 From Our UsersThis works very effectively and left my mouldy shower ceiling clean and white without any effort but……

    What the Amazon listing does not say that it isn’t recommended for painted surfaces or ceilings.

    Fortunately, it doesn’t seem to have done the paint any harm.

    I suspect that they don’t recommend use on ceilings because of the inevitability that you will be looking UP as you spray. I did get some eye-irritation but that was dealt with by prompt water irrigation and then eye-drops. Eye protection before you start would be a good idea!

    There is an over-powering smell of chlorine, so you really must ventilate well. The chlorine smell was quickly apparent all over the house. It is still noticeable in the bathroom one week later but it is fading.

    This ‘chemical warfare’ works extremely well but a bit of extra care is the price you pay for the quick, effective and effortless removal of the mould.

    A qualified recommendation.

    I read the instructions and it said to leave it for how many minutes to be properly applied. I didn’t have a lot of experience with mold and this time I had a bad case and I expected it will make it easier to clean the mold after 3 or 5 minutes (or whatever was the adviced time), but when I wanted to clean the mold from the wall I was surprised to see that the mold completely disappeared. I know this is properly what would happen with most properly chemicals like this one, but as I said I didn’t really have experience with mold and I can say I am positive surprised.

    I have fought countless wars against mildew over the past few years, and I have tried everything and nothing has even come close to being as effective as this stuff is. the bottle says to spray and leave it to work for 30 minutes but the wall will be spotless in 5 minutes, all that’s left to do is wipe down the wall and done, no elbow grease needed.

    Only “downside” is that these are some strong chemicals, very strong smell and please make sure you are using protective equipment when using it, wear gloves and make sure the room is well ventilated.

    But I seriously recommend this stuff!

    This mould remover is absolutely fantastic. I sprayed this on the roof of my bathroom which was covered in black mould, left it there and the mould just disappeared. It could not have been easier! Really wish I had taken before and after pictures. I’ll be stocking up on this!!

    About to give up on a bathroom blind covered in mould after scrubbing with bleach and other products then i read about this… Within 5 minutes its gone.. Every bit of mould gone.. Ive now tried it for mildew and used on shower screen etc to shift stubborn water marks and it worked a miracle on those too… Only downside is you have to spray and run as very toxic so ventilate well.. But theres no scrubbing all you do is wipe over area with damp cloth and thats i

    Oh wow where do I start?! This is the best mold removing solution I have ever tried.
    It’s amazing and it really does work. I sprayed plenty of the solution onto the black mold, left it half an hour, went back to it and, Hey Presto, the mold just wiped away without any effort.
    I highly recommend this product to anyone who is struggling to clear black mold away.
    Thank you

    Worked within 10 minutes on a stubborn mould patch, it disappeared completely , It is quite a thin spray so if you’re using it on a ceiling like I did put something underneath to catch the drips, I used far to much the first time, the second patch I just sprayed once and it still worked it’s magic! It does leave a bleach smell behind but I don’t mind that – great price too.

    For as long as we have owned our house we have struggled with black mould/condensation due to it being old (1905) and having no cavity. In the past, we have tried different mixtures from vinegar, bleach, other mould sprays plus have used a dehumidifier along with 1 damp boxes in nooks and crannies alas we have a constant battle with the black stuff! Every year we dread autumn through to spring, but this year we found this spray and it has been a game changer.
    We have mainly used it on walls, grout and windows and this little bottle has cut out hours of scrubbing and lots of stress and worry. I don’t like the idea use of using chemicals but it really worries me about the health effects the damp has on my family and this 5 product has made a significant impact on our lengthy battle with trying to keep it away. I would thoroughly recommend it and just advise that people follow the manufacturer’s instructions.

    I had some mould growing by my front door, I sprayed it and boom! Immediately I could see the mould starting to disappear, after a very short amount of time it had completely gone! This stuff works like an absolute charm, will be buying again! It is *really* strong though and it has a very potent smell, gloves & a well ventilated room is a mus

    I have been using HG Mould Remover for several years, and after experimenting with various alternative products making similar claims, I can confidently say that HG Mould Remover stands out as the most effective.

    However, it’s worth noting that the product has a potent smell, so I advise using it in a well-ventilated area. One drawback is that the bottles have a tendency to leak over your hand while spraying, so I recommend using gloves as a precaution.

    We was constantly get mould above the shower after many times clean it it just kept coming back. Used this stuff, even after spraying you can see it turning into a lighter brown and by the time 30 minutes is up ceilings completely clean with no mould at all.
    There is a very strong, bleach smell almost like a swimming pool smell, but don’t mind it as long as it worked.

    Golden Review Award: 2 From Our UsersWe have a mould issue in my daughter’s bedroom and I’ve tried every supermarket cleaner, but it was just cleaning the mould instead of removing it. Did an Amazon search and came across this product. Not a known brand, so I was unsure. But I had to listen to the thousands of reviews and I’m glad I did. After 15 mins, the mould was gone!!! No scrubbing…just gone…like magic! I’m not exaggerating! This will now be the only cleaning product for me. Your house will smell like a swimming pool, but small price to pay for no mould affecting my daughter’s lungs! Use an old cloth to remove as it will bleach the cloth. Excellent.

    Golden Review Award: 2 From Our UsersOmg i have tried a lot of things for mould and grime but this product is another level my bathroom is like new. I sprayed it on all grout and tiles and round the window and no word of a lie my bathroom is like new. I must say it is VERY VERY strong and takes your breath away and makes your eyes sting a little and water but for the after look what i got in my bathroom that was all worth it! I would defo recommend this to anyone as it does everything and more what it says and i have just ordered another 4 bottles as i used it not only for mould but to clean my toilet bath and sink and all is sparkly clean plus on two mouldy windows and my god what a difference it has done. Thank you so much for producing this product i cant recommend it enough.

    Golden Review Award: 3 From Our UsersI didn’t think the product would live up to the hype or deal with stubborn black mould spots – but it was incredible! It removed mould off painted walls, bathroom sealant, tiles, grout, paint, wood, ceramic tiles, and window frames. I’ve never seen anything work so fast and so effectively. It looks like we’ve entirely renovated the bathroom and installed new windows!

    With lowered heating due to ridiculously inflated heating bills and very wet weather we’ve had issues with mould that simple ventilation could not resolve as the outside air was always wet and the weather permanently damp, drizzly or wet and mould started to develop from the windows into the room. Even with open windows and lots of ventilation, lowered heating caused mould to take hold.

    This product has been a game changer.
