Interesting to read all the different suggestions !

I’ve only ever used bleach. I’ve f you find the mould keeps returning, you may need to consider re grouting

White vinegar is a good thing spray on leave for 30 mins then rinse off

Bleach doesn’t kill the mould – white vinegar does. After spraying with a vinegar solution and leave for a while, the go crazy spraying it with bleach to get the grout back to white

Bam Spray removes mould and grime from tiles quite easily. Spray it on, scrub it with a soft brush and rinse off with water. If you are cleaning a tight corner you can use an old toothbrush. You can also clean marble with it. We cleaned an 89 year old headstone at a Cemetery. As the lettering is lead we did those sections slowly to make sure it didn’t go under it at all.

if bleach doesn’t work etc then you will need to re-grout. you can do this yourself for cheap

I make a paste of nappysan and water and use a toothbrush to scrub the grout.

I forgot about Clove Oil. I did get some Selleys Mould Killer the other day and it seems to have worked.

Ive got oil of cloves in my medicine cupboard. I always use it for tooth aches. It tastes yuk but anything to get rid of toothaches. Hope it works.

Hope this helps:

why remove mould with clove oil?
We have a great reference from a Brisbane City Council inspector reviewing flooded, smelly, already mould-growing homes. He advised to keep away from chlorine bleach to clean mould as it only ‘bleaches’ the colour out and does not kill the mould. “It’ll be back in a few weeks,” he said. “CLOVE OIL is the best!”

Great question, following with interest, especially tips for old grout in an old home…..

The only thing that will work is OIL OF CLOVES, you can buy it at the chemist. It may take 2 or 3 goes, but it works. I used it after the 2011 flood to clean the mould from all the woodwork where the flood water came. It is a very small bottle(10 mls) directions on the bottle.

Maybe get some professional advice if it is persistent.

Its not a natural cleaner or anything but I use a product from White King, especially for bathrooms and cleaning grout. Its very good and works every time!

Exit mould and bleach do not get rid of the mould. They only bleach it. I’m not sure how to get rid of it either. I wish I knew.
