Removing mould in walk in shower

Apologies if there’s already a thread on this but search hasn’t turned anything up. Despite making sure both bathroom and shower are well ventilated I’m starting to get a problem with mould building up on the grouting. In the past I’ve never found the mould removal sprays to be very effective. Can anyone recommend a product or method that really works please?

Neat bleach on a toothbrush, scrub and rinse off. Not perfect, but it's the best I've found.

I have used this stuff from 'Must Have Ideas'. I know it works, though, despite its advertising, the mould does come back, but after a long time.

Website says it's out of stock ATM. If you google 'mould magic' there seem to be a few similar products available which are probably worth a try.

I have used mould magic on the sealant around the shower and windows and it works really well, it removes all the black.

However, I’ve had no success using it on discoloured grout, I had to scrape out the grout and replace it, not an easy task.

Yes.I’ve used that, too. My partners shower was covered in black mould and it cleared it even on the sealant. I did, however, find a similar product in a local hardware shop but not sure if it works as well as I haven’t needed it. As long as the product has bleach in a gel base so that it sticks to the grout it should do its job.

This is the one I’ve just bought.

I always use Astonish Mould Mildew Blaster. for the grout between the tiles.
I've found it brilliant although on stubborn bits you may have to do it twice.
Another tip is to put a moisture trap with crystals in the bathroom. It helps to soak up the moisture.

I found HG mould remover works but I've tried lots of different things including home made and most remove the mould but it always comes back.

If the mould is at the bottom of the tiles I fold a long length of loo roll or kitchen paper and put it along the edge. Then drench the paper in bleach and leave for as long as you can before removing the paper and rinse before use.

Yes I’d agree with this. I bought some of those with the crystals and I’m amazed at how much water they collect. We do open the bathroom windows but still they fill with water.

I'll save this thread for reference!

A plumber told me that softeners eg hair conditioners, fabric softeners, contribute to mould build up in bathrooms and washing machines.

Can you have an extractor fan fitted in the bathroom? Even if it's well-ventilated moisture could still remain, particularly in humid wet weather.

Greyduster Mon 27-Jan-25 15:30:55

Same as Septimia. Works well.

woodenspoon Mon 27-Jan-25 15:31:27

We have an extractor fan plus two windows in the bathroom and we still get mould in our walk in shower. It’s only two years old so I’m quite fed up,

Granmarderby10 Mon 27-Jan-25 15:48:03

I don’t remember mouldy bathrooms from when I was a child, so am wondering if plastic baths and shower bases contribute to the problem. We didn’t have double glazing and for many years no central heating so….?
I do consider an extractor fan essential now- though they are so noisy.

I don’t use fabric conditioner any more. I use white vinegar instead. Looking back I don’t know why I used it for years.

Yes we've got an extractor fan in the bathroom as well.
Our bathroom's only small. I buy the Kilrock crystals to put in the moisture trap. I put one in each of the bedrooms on top of the wardrobes from late Autumn until Spring. They fill up with all the moisture from people breathing. Well recommended.

Thank you ladies, I can always rely on this community for help. According to the website they’ll deliver Mould Magic by the 9th Feb so I’ve pre ordered it. 🤞

Do yo put it into the dispenser, Maybee?

I like flash bleach & toothbrush.
Just done around my mums patio door with this hack - dampen folded paper towel, spray bleach & lie across the silicone & leave overnight.
Worked a treat.

After trying lots of mould cleaners over the years, the best by far is Cillet Bang Black Mould Remover. Just spray and walk away.If it’s very bad, spray again then leave for an hour and gently brush grout with an old toothbrush.I rarely have to do it twice tho.

BlueBelle Mon 27-Jan-25 16:53:20

I m another who just uses neat bleach leave it on for a few hours then use the spray to wash it off
I haven’t found anything else any better

I do. I’m not sure if it can damage the machine if used over a period of time; mixed reports on that, but I’m going to risk it. I did buy a large container of white vinegar but it had an extra ingredient so I just use distilled malt vinegar in the machine just in case. I only use a small amount and not for every wash.

NonGrannyMoll Mon 27-Jan-25 20:17:01

Nothing worked for me either until I used Cillit Bang Power Cleaner (got it from Sainsburys). Mind you, my friend used it without success, so I'm wondering there are different moulds which respond to some things but not others. Bleach can work but it also bleaches out colours, so don't use it near wallpaper, etc.

Sorry, computer wanted to say "there" not "whether". Sausage fingers or IT gremlin, one or t'other.

Thanks.

I suppose the worry might be that vinegar damages the seals but I'm not sure.
