Your insides must be knackered :wink:

Great, now try doing any of that in a rental property with a landlord who doesn't care?

Yes, the liquid works, but the bottles are trash. I have 50% failure rate with the spray mechanism.

Bleating or just giving advice from practical experience? I haven't got a bottle of the HG in the house so (genuinely) what is the extra active ingredient in the HG over bleach?

EDIT : I'll answer my own question. Its active ingredients are Sodium hypochlorite 3% (bleach) and Sodium hydroxide 1%. So its the Sodium hydroxide which is extra. Sodium hydroxide is caustic soda / NaOH.. And looking up NaOH - it "will clean the grout really well, but it will weaken and you will get soft grout essentially many grout cleaners use NaOH as an ingredient". So cleaner, weaker grout.

cheers. will order

Fantastic stuff.

Totally agree, it's by far and away the best product of its type I've used.

Better than bleach?

Thanks just ordered

I saw this in store earlier today but didn't know if it was any good have to go back and get some

+1 for positive reviews too, great stuff.

Yep, this stuff works, far better than the normal high street brands.

Yeah, this stuff is by far the best.

Addicted to this. Wish I had a Homebase near by

Will this stuff work on really ground in mould?

Through using crap cleaners to try and remove it.

My imagination obviously was a bit overactive.

I'm thinking so.

I've had this, but I didn't find it any better than the astonish one in the green bottle that costs a quid from home bargains tbh, they both work the same & get rid of all mould with no effort.

Haven't tried this one, but find the Cillit Bang Black Mould remover really good.

does this work on silicone!?!

Iv used it on silicone many times and never turned yellow.

Yea best stuff I have found for mould by far
Cheap and works in no time
But I leave it on over night, hasn't caused any harm

Great to spray when clean to prevent mould coming in first place


Silicone no problem

Agreed with comments, we use this stuff, does the job. Make sure room is well vented and leave overnight if you can. Its very strong.

It is very good. Yes, use in a ventilated environment but I found that won't work any better having been left overnight; it takes mins to work and if the stain is deep, several applications may be required but do so every 5-10 mins rather than every 12 hrs.

Flash with bleach works very well for me and it's usually £1. I don't have much mould that often though tbh.

I had the HG stuff and found it to be great until the sprayer stopped working. It stunk the room out. Now I just put some thick bleach on an old toothbrush and put it on the affected areas (no scrubbing - just use the brush as an applicator) and it does the job fine without so much stink.

Ordered, thanks OP will collect tomorrow, I needed a tiny bag of quick drying cement so HOT.
BTW never guess my local store

MOLD Flintshire. Wales.

Brilliant stuff.

​Or....or.....or...you can use 1 part bleach 3 parts water in a spray bottle...spray it onto the affected area and leave for 31mins and the mould is also miraculously gone

Can u use this outside on mouldy patio?
(Serious question!)

Hg make brilliant products, highly recommend.

homebase website rubbish....won't let me 'click and collect' ie pay now, only 'reserve and collect'. So price not guaranteed

Brilliant stuff... smells a bit though!!

tried & tested great stuff hasn't even returned the mould

click and collect still working fine for me

If God made a mould cleaner, it would be this!

Addicted. In what way?

anyone used this on shower en suite tiles?

Can this be used to remove the mould from damp walls?

does this work on food?

does this work on food?

Yep, and the same brand grout cleaner. Both outstanding, much better than the basic bleach options that others are bleating on about

Bleating or just giving advice from practical experience? I haven't got a bottle of the HG in the house so (genuinely) what is the extra active ingredient in the HG over bleach?

EDIT : I'll answer my own question. Its active ingredients are Sodium hypochlorite 3% (bleach) and Sodium hydroxide 1%. So its the Sodium hydroxide which is extra.

This stuff is the best !
The results are incredible - once a year and no mould for the remainder (in our case).
Be Careful of getting it on paintwork .. cuz it will bleach that too.

Not a clue, as I don't make the stuff, try asking the manufacturer.

Unlike you, I've tried both.

Weaker grout? Better off with dirty grout! Weaker grout is a really bad idea - unless you particularly like water leaking into plaster, wood etc.! :confused:

probably ok if you plan on repainting. at least it will the kill the mould eh...

This is just bleach and water...

fool and money / parted.

iron lungs over here :wink:

I use dettol and other brands found in Poundland and Poundworld for one quid. This is no better. Waste of money on something that's only one quid. Also use dehumidifier in home winter.

It's good stuff. Just spray it on and leave it for a while usually the mould disappears without wiping. It will struggle with some mould but overall it's good.

Wear gloves, this stuff removes skin like it does mould. Other than that, this is great. Got a load from B&Q last time they were on offer

just try this

Thanks. Has anyone tried this on mound outside?

Thanks

Yes, the liquid works, but the bottles are trash. I have 50% failure rate with the spray mechanism.

This stuff is awesome at getting mould off but be prepared to leave a window open for a few days to get rid of that bleach smell!

Agree. Great product. I have tried cheaper alternatives without success. I have also had numerous bottles with a dodgy spray mechanism. Now, I tend to pour the new bottle into my old one. Simples.

Heat added. Hope it can get mould off cheese :smile:

No it's not. It also contains Sodium Hydroxide, which is why it's more effective than bleach alone.
Not a good idea for shower tiles, though - weakens the grout, which can mean water penetration of walls and floors.

Stop stop stop everyone!!! Before you buy this stuff get on this.
The most effective mold remover that I have ever had is the big £1 ( or 99p) orange sink/plug unblocked that you get in home bargains or pound land etc.
Just pour it onto the mold, leave for 15-30 mins and wash away. No need to scrub.
It's powerful stuff and you might want to pour it into an old spray bottle to dispense easier. From what I can imagine is almost certainly the same stuff as on here but not advertised for mold.
Honestly try it, you will be staggered. £1!!

Any idea how to get rid of black in the tile grout?

I 2nd that, used Cillit Bang on various different fabrics, works wonders instantly with little effort.

Agree, the best. This was originally recommended to me by my local environmental health office

Would it work on plywood? Shed ceiling covered

Is this good for damp shower rooms?

Sodium hydroxide is caustic soda which is can be bought for about a pound in most supermarkets - a small packet will make many litres of diluted product. It's also the main ingredient in sink unblockers/ drain cleaners/ patio cleaners which is why people on this thread have had success using those products.

I can't understand how so many people have mould problems in their house. Houses should not get mouldy. If you have black mould, your problem is high humidity causing condensation. This is almost always caused by poor ventilation. Long term the mould will be the least of your worries as serious structural damage will occur over time. If you suffer with mould in your house do yourself a favour and look into improving airflow and ventilation - a decent extract fan in bathrooms, cooker hood venting to outside and if that doesn't work look at positive input ventilation systems such as drimaster or envirovent. Yes they cost more than a £3 bottle of bleach but it's the proper way to resolve the problem.

this is also very good 750ml for 1.75.

this stuff STINKS I am unable to apply it myself anymore , as I get a severe headache after applying it.

I would advise to SPRAY AND RUN !!!!

Clearly, there's a lot of mouldy houses out there....

It can we had some behind a cupboard- its brilliant stuff

Bleach will do exactly the same job. Easy from B&M. Just put a bit on top....or whole bottle as it it 40p each. Leave for 30 minute. Open window before. Rince with a lot of water. Job done. No mold in my bathroom since I remember been respo sible for cleaning bathroom :-)

This will stop my PS4 going mouldy. Thanks OP.

I think most people use it on the silicone around their bath/ shower mate.

Yep, for sure, kills the mould off for monthsand months as apposed to bleach which just kills it off for a week or so (in my experience). It's like super magical wizardry bleach concentrate! DO NOT BREATHE IT IN! :laughing:

Great, now try doing any of that in a rental property with a landlord who doesn't care?

A lot of rented houses have damp situations due to landlords not properly fixing leaking roofs gutters, window seals and many more. it's not just homes owners that use this lol :stuck_out_tongue:

another vote for fixing the underlying problem. A dehumidifier costs little to run and a Karcher window vac will help by removing moisture from windows/ shower tiles, even the floor by the shower if you get that wet

anyone know if this would work on the ceiling?

​Yes! Bleach takes a lot of effort but with this stuff you just spray it, leave it for 30 minutes and return to no black mould (look at the before and after pics and reviews on Amazon). We used it for the first time on Thursday after trying to get rid of it with bleach on Wednesday. It's awesome!

I know it's a mould spray but has anyone tried it on chrome taps with a view to remove limescale?

Bleach and warm water works wonders and is alot cheaper

Is it any good for ceilings & around window frames? Thanks in advance

tried the cillit bang one. Didnt shift the mould, but the hg one did :smiley:

Try white vinegar or some other mild acid. This will not work on limescale as it is alkali.

​haven't tried this but do find Dettol mould and mildew remover a lot better than Cillit Bangs incarnation.

If you click on the link to the item at the top of this page. it also shows they have the other hg products including limescale remover. Same price too! Never tried that one but all the hg products I have used have worked wonders!

awesome stuff this! I swear by it! always does the job in minutes! heat added.

Always best to eliminate the mould cause. However, this product is very good at removing mould. Make sure you use the stated precautions. I think I wore eye protectors and specialist gloves. Maybe I went a bit overkill. Could have got a respirator too.

Can anyone advise.

Is this fine to use on painted wallpaper? Will it damage the wallpaper or strip the paint?

I have the astonish stuff from B and M is that OK to spray on wallpaper?

Does this work on underpants?

Oh yes! Best product ever for removing black mould from anything.

This - save yourself £3.

I just use a strong Bleach, pour some into a container and then use a paint brush to to spread it on the walls, ceilings etc. Works very well

I tried the UPVC cleaner after having such a great outcome with the mould remover, and was very disappointed with it, so not all HG products are as great I'm afraid. Don't know about any other though.

Just watch this stuff if you have any alloy fittings, it's safe enough with chrome but it does etch alloy. I speak as the voice of experience after this etched all the alloy strips in my wall tiles.

No it doesn't on silicone! Can't get rid of it tried the one from Lidl no good even tried neat bleach still black dots on silicone around bath- so will give this a go

This is brilliant stuff. I use it periodically around the shower/bath to keep on top of things. Works a lot letter than bleach, we were about to try to remove and replace all the grout, it looked so bad (after trying other cleaners including rubbing bleach into it with a toothbrush), then gave this ago after reading about it online and it all came up white!
For those asking about silicone it sorted the top layer of mould with 2 applications but unfortunately there were some odd spots that were like embedded in the silicone and it couldn't do anything about that, eventually cut it out and re-siliconed it. Still looked much better than it had though.

I could also only reserve, and when I collected it, they wanted to charge me the higher price. When I pointed out I had reserved at the lower price, they honoured the lower price.

yeh it scans at normal instore price but they price matched the reserve price.

Yup. Bleach products generally contain sodium hydroxide so there is nothing really special about HG.

I use Astonish Mould & Mildew Remover which is just as good as is just a quid -

Safety data sheets give you the exact compositions, its all the same stuff - sodium hypochlorite , sodium hydroxide, and surfactants.

Domestos Thick Bleach Original Blue

If you live in an older property with solid walls (ours are 2 foot thick) ventilation is only practical in some areas. Moisture will then find the coldest part of a wall and condense out.

We use a dehumidifier to help up some patches of mould will appear in preferred spots which this spray removes for quite a while.

The house has stood for 300 years so I don't think a little bit of mould is going to cause any great structural damage. :smiley:

Modern living doesn't help as 300 years ago ventilation was provided by draughty windows which modern day double glazing has sealed up. :neutral_face:

Beast mould killer

Don't work for me load of crap

This stuff also works a treat in the washing machine: chances are if you pull out the soap drawer the machine will be covered in mould if its not been cleaned before, spray some of this stuff around there leave for a bit till its gone and rinse with water.
Also excellent for cleaning the rubber seal in the machine door.
Just make sure you rinse well after save you bleaching any clothes.

Can this be used on painted wooden window frames? Was looking at some similar by stardrops which said not to use on wood.

Sodium Hydroxide is just caustic soda, about a £1 from homebargains for 1kg,
also great for plugholes

like I said, fool/money
