Mouldy grouting in bathroom - this REALLY works!!

I'm not sponsored by the company, honest, and I have a history on here (Yoni massage, centre parks, poo troll etc) but I've just used this mould spray in my bathroom and OMG does it work!
I've had major black mould problems in my bathroom grout and was dubious that anything would shift it but bought this stuff on the recommendation of other MN-ers and sprayed it on earlier today.....and have been amazed by the results - seriously sparkling white grout - it changes colour before your eyes - you do not need to scrub or anything, just sponge the spray off after. Amazeballs! I seriously thought I was going to need the bathroom re-grouting before this.

Just had to share, for those who have a similar problem. smile

It does smell so you need to ventilate well when you spray it on, and it does bleach so be careful (don't get it on your feet like I did stupidly standing in the bath while I sprayed it - realised just in time. Have clean feet now anyway!)

(Disclaimer - I know all about more ventilation needed - treat the cause of the mould etc etc but just not possible in my tiny north facing bathroom)

I have to say I've also found the stuff amazingly effective, though I did need to apply it more than once.

When I was selling my house, I found it had an almost magnetic attraction for viewers. If I hadn't had some for a while, and decided I'd seize the opportunity and de-mould, I could guarantee that while the HG was at its smelliest, the phone would go with a viewing request.

Cannot guarantee this will happen for anyone else, obvs.

Really...? Nothing has ever worked on my mouldy grout. I had given up hope. Shall give it a go. Now if you could just tell me the magic product that re-plasters the ceiling and transforms the vile bright turquoise paint job into something tasteful all by itself, my bathroom nightmares will be over <waits hopefully>.

Yep. That HG stuff transformed my mouldy bath sealant from nasty black to virtually stain free. The worst bit was very pale grey after treatment but hugely improved.

The dettol stuff in the green spray bottle is good too, but scarily strong.

BoreOfWhabylon Fri 22-Nov-13 14:01:50

Thank you Selks, I'll be ordering some for my tiny, cold and mouldy bathroom!

MinimalistMommi Fri 22-Nov-13 14:50:19

Right I'm buying some! Thanks for the link!
For anybody that is doesn't work for, lakeland have a 'forever' guarantee, keep you receipt and if you're not happy even if you've used it you will get you money back. Lakeland are fabulous!

magimedi Fri 22-Nov-13 14:59:06

I knew it was going to be HG before I clicke dth elink!

All their products are amazing - not cheap but bloody wonderful stuff.

See here :

The Bath shine (which Lakeland also sell is fantastic - you need such a small drop of it.

PS I don't work for them, either!

lucjam Fri 22-Nov-13 15:01:59

does it work on those orange stains that you get as well a the black spots?

BrianTheMole Fri 22-Nov-13 15:05:56

What am I doing wrong? I tried that stuff and it didn't work.

FlightofFancy Fri 22-Nov-13 16:38:30

Does it really work on silicone sealant? If so, I'll be taking out shares in it. I swear by Dettol for grouting, but that doesn't touch silicone. We've got black mould on the sealant all round our windows - previous owners must've been the worst at ventilation - so if I can get it off I'll be delighted!

lalalonglegs Fri 22-Nov-13 16:40:45

I don't have black mould on my grout but I do on the silicone - does it work on that <hopeful>?

weepingvipers Fri 22-Nov-13 16:58:22

Another who knew it would be hg! It works on silicone but can take a few applications. Their lime scale remover is the best but do not leave it on too long as it will take the chrome off too!

When I clean for people I use hg products for almost everything.

sleepyhead Fri 22-Nov-13 17:19:54

Yes, it works on silicone but as weepingvipers says it can take a while.

You need to make sure it stays on and doesn't just run off. I got most of the bad black stain off the white sealant by putting a folded up piece of kitchen towel against the stain and saturating it with the spray. I also left it on a good while.

It works on the orange stuff too. That's just another kind of fungus I think.

Selks Fri 22-Nov-13 18:35:16

BriantheMole, did you leave it on for a good half hour?

MyMILisfromHELL Fri 22-Nov-13 18:39:11

I've found Dettol Mould & Mildew to be really effective at removing mouldy grout from bathroom tiles.

IamInvisible Fri 22-Nov-13 18:42:11

We've got some. The smell is horrendous, even if DH uses a tiny bit in the bathroom with both windows open, I am guaranteed a migraine and DS2 can't breathe from his Asthma. It is good for getting rid of the mould, but it is awful stuff.

Aquariusgirl86 Fri 22-Nov-13 18:54:32

Thanks for this, just what I need!

Doinmummy Fri 22-Nov-13 18:58:01

Really?? It really really works on sealant? I'm dead gerrinf some then .

Doinmummy Fri 22-Nov-13 19:02:31

The black spots on my bath sealant are sort of 'in' the sealant IFKWIM. Will this stuff work?

lalouche Fri 22-Nov-13 19:10:34

Putting neat bleach on a piece of cotton wool and leaving overnight also works a treat on the black mould on silicone. Doesn't work on the orange stains, though, so I am going to check this hg stuff out!

JohnnyUtah Fri 22-Nov-13 19:15:03

The dettol spray does get rid of the orange colour

lalalonglegs Fri 22-Nov-13 19:17:55

I find Grotbuster (which smells suspiciously like neat bleach) works on the orange stuff or I have a steam cleaner thing that blasts it all away but my silicone always looks grim within weeks of replacing it. I often worry about the sort of couples who run B&Bs in "Four in a Bed" coming and inspecting it blush.

CatelynStark Fri 22-Nov-13 19:21:07

I knew it was going to be HG too - magic stuff!

pixiegumboot Fri 22-Nov-13 19:23:42

Oooh that is so weird, my friend told me about this exact same stuff today!

Selks Fri 22-Nov-13 19:34:31

Re working on sealant - I used it on a black mildew stain on sealant and it worked for area two inches by one inch of black completely gone. Can't guarantee it will work for everyone - maybe depends on the severity, but it's bound to reduce it anyway.

Selks Fri 22-Nov-13 19:37:11

HG got rid of all the orange stains too.

KirstyJC Fri 22-Nov-13 19:39:28

Oh great - I find this thread the day AFTER I spend ages resealing the bath and re-grouting.....!grin

Will stock up for next time though!

Doinmummy Fri 22-Nov-13 19:59:01

Is it only sold at Lakeland?

longingforsomesleep Fri 22-Nov-13 20:00:57

The orange staining drives me round the bend! I keep a nail brush in the shower and spend a few minutes every day just scrubbing the grouting - but it's back again within a few days. Builds up quickly on the shower curtain too. So I'm going to give this a go.

I pour neat bleach on the sealant and leave it for an hour or two - always gets rid of the black mould.

didireallysaythat Fri 22-Nov-13 20:32:05

I get HG at homebase (on their 15% weekends). If their limescale stuff is half as good, I'm getting that next....

Selks Fri 22-Nov-13 20:51:50

I bought mine in B&Q.

Selks Fri 22-Nov-13 20:53:15

Oh no Kirsty! grin that's typical.

BrianTheMole Fri 22-Nov-13 21:07:31

BriantheMole, did you leave it on for a good half hour?

Hmm, well I say, what am I doing wrong, but actually it was actually dh that did it, not me, so I was trusting he did it properly grin. I've just sprayed some on, so now I will wait. For half an hour. And no less. It stinks. Tick tock tick tock. <fingers crossed>

BrianTheMole Fri 22-Nov-13 22:00:22

It still didn't work sad. Gutted! Oh well, it was worth another go.

Selks Fri 22-Nov-13 22:13:22

Oh, what a shame! I wonder why it didn't work for you sad.

Selks Fri 22-Nov-13 22:14:06

Was there no improvement with it at all?

LongStripedScarfWearer Fri 22-Nov-13 22:17:44

I've tried it on our silicone sealant a good few times to no avail. Works a treat on the grout though.

thenightsky Fri 22-Nov-13 22:21:08

HG is mega. It does take a few goes on silcone sealant though. I found it worked best if I sprayed it on dry silicone and left overnight. Then repeat this every night for a week.... result is white silicone seal.

thenightsky Fri 22-Nov-13 22:22:08

LongStripedScarfWearer Dry the area you want to treat before spraying on. Makes massive difference.

BrianTheMole Fri 22-Nov-13 23:40:28

Was there no improvement with it at all?

No, not even a tiny bit. I started with such high hopes thinking dh must have done it all wrong as well grin
Oh well, back to hiding the mouldy bits with carefully placed bottles of shampoo!

Selks Sat 23-Nov-13 00:19:43

That's quite bizarre Brian; you must have super-mould!
And yes to the strategically-placed bottles; have had to do that myself before now smile

Doinmummy Sat 23-Nov-13 00:27:20

I have mould that is sort of ingrained in the silicon. Will this stuff work on that ?

ThenSheSaid Sat 23-Nov-13 00:43:46

I just ordered some on amazon plus some grout cleaner. Both have great reviews.

Selks Sat 23-Nov-13 10:42:09

Um, you know the orangey staining......Horrors!! shock

sleepyhead Sat 23-Nov-13 11:22:54

I try not to think about it selks, so thanks for that grin

We didn't get the orange stuff until fairly recently (last couple of years) oddly enough. It must have colonised the bathroom at some point and be hiding somewhere the bleach doesn't reach, because it always comes.back.

cavell Sat 23-Nov-13 12:10:59

I think the answer to stopping getting the orange stuff building up is not to use bars of soap and be sure to wipe any splashes of conditioner away. Use shower gel or liquid soap.
Once I managed to persuade my old-fashioned dh to stop using bars of soap in the shower, we stopped getting the build up of orange gunk. I understand it feeds on the fat found in soap bars.

Selks Sat 23-Nov-13 13:43:39

Sorry Sleepyhead grin

ParsingFancy Sat 23-Nov-13 13:54:47

Another one who just knew it would be HG.

I like the tissue idea, though, as I suspect 'twas a sneaky dribble of HG that took the paint off the window sill. It probably sat there undetected for a while.

MinimalistMommi Sat 23-Nov-13 15:49:12

I have not he sealant in the bathroom now it stinks!

1charlie1 Sat 23-Nov-13 16:35:17

We've got this. Have only ever done the grout/ seals with it. Could you give your shower curtain a spray with it, leave it for a bit, then run it through the wash as normal?

MinimalistMommi Sat 23-Nov-13 16:54:10

I'm putting it on again for another 30 mins, it hasn't completely worked first time around, lightened some of it but a patch of really black mould own sealant doesn't seem to be working. Is it ok to leave this stuff on overnight?

didireallysaythat Sat 23-Nov-13 17:28:53

I spray orange tinged shower curtains with a kitchen bleach spray. Then wash in the machine...

MinimalistMommi Sat 23-Nov-13 17:45:07

So the second thirty mins made it go brown, so I seem to be getting somewhere...

thenightsky Sat 23-Nov-13 20:02:48

Yes, leave it on overnight. I always do. But I make sure the area I'm treating is bone dry before I spray.

JollySeriousGiant Sat 23-Nov-13 20:05:11

The HG didn't work here. Might have to try it again if you lot are recommending it.

I used the cheap Astonish Mould and mildew remover spray from Home Bargains (green bottle) for £1 and it worked wonderfully, orange and black all gone from the grout lines and sealant, I did it about 4 or 5 days in a row and let it stay on overnight. Now I do it weekly and theres been no more mould at all,

I never get mould on the grouting or sealant around my shower cubicle.

The way to prevent it is to dry the whole thing - tiles, glass panels, door and base - after every use. It sounds a pain but only takes a couple of minutes and I use the towel I've just dried myself with.

I get plenty of mould growing on the walls and ceilings though <sigh>

What does the HG stuff smell of? Is it bleach?

MinimalistMommi Sun 24-Nov-13 06:06:13

Stinks of chlorine to me!

Aquariusgirl86 Sun 24-Nov-13 08:17:46

Bought some yesterday.....haven't tried yet but I see people are saying it's stinky and leave it over it so stinky that it will stink the whole upstairs out?

MinimalistMommi Mon 25-Nov-13 20:50:56

Leave a window open a crack. It has worked but it definitely needs more than two 30 min applications. My husband is very pleased by it, means we don't have hassle of re grouting now.

ThenSheSaid Mon 25-Nov-13 21:37:17

I ordered this on Amazon very early Sunday morning and it was delivered at 10:00'ish on Monday morning. That's fast!

Anyway, it does work but I can't help but think its just a bottle of bleach ????

Any chemists around to check.

It faded the black to a light grey. It looks a lot better but I think I will still redo the sealant. It doesn't take me too long.

Selks Mon 25-Nov-13 22:01:24

It's like super-bleach ThenSheSaid. I think it has bleach and something else in it. It worked far better than bleach for me.
