Im after a mould, mildeew & fungus killer that works. Most important is killing the indoor mould .
So many products on the market, I dont want to waste another 4100 on something that really doesnt work.

I know that bleach is not good at killing mould, it keeps coming back .

Wet and forget, I havnt had any luck with that either, except one test area where I poured heaps of it on (poured , not sprayed)

Any suggestions ? Its the driveway, outdoor door sills & surrounds & indoor ceiling & bathroom walls.
The driveway gets quite a bit of water flowing over it in winter, so any long term killer would probably get killed off.

Im slowly re-painting with anti mould paint. That works very well , after 3 years only a few spots here & there on the bathroom ceiling , but this winter I think even that will need some anti mould treatment

And what should I use to remove the mould stains after its been killed off ?

Cheers

Bleach will kill active mould etc, but not spores, so it will come back.

I have only used 30 Seconds, so can't comment on Wet and Forget.

To stop mould in a bathroom you need to improve ventilation or prevent moisture from occurring. It can't grow in dry conditions.

What is causing the mould?

We have a Steam Stopper/Shower Dome and have no mould issues in our bathroom on south side of house.

A friend of mine is a commercial cleaner.

She told me a few years ago that bleach only turns the black mold white, it does not kill the mold.

Apparently soap kills mold but does not remove the mold. it can take a few weeks to fall off.

Try sugar soap.

I hope that helps.

You really have to treat the cause as otherwise it will keep coming back. If you leave windows open and it is well ventilated, and you are still getting it, then it could be a sign of bigger problems/

Can't remember the ratio/mix, but vinegar and baking soda are supposed to kill most moulds. A Google search would help with the mix.

People often mistake me for an adult because of my age.

Keep calm, and carry on posting.

You got it. White vinegar is the man. Green, and it kills biological matter. Google will give a 1000 uses. It is an acid, acetic acid, weak enough for us to eat but strong enough to kill less intelligent matter!

However, Borax may be hard to find as it is now classed as hazardous substance. Quite a conspiracy theory around the classification, as it is less toxic than salt.

However, Binn Inn carries it in 500g quantities ( or used too - haven't replenished my stash yet)

It does work for curtains, etc, and recommend it for that purpose, but not so sure for wood and similar surfaces as the active ingredient sodium hypochlorite ( Bleach) is ionic and will not penetrate wood, etc

Bleach + curtains = faded colours + rotting yellow fabric when the sun hits it

:-)

Ive tried bleach based products . Not the best, and the fumes are pretty bad when used indoor on large areas.
Most of the products commonly sold seem to be bleach based. Not sure Id like the house stinking of vinegar either

Last thing I want is ceiling paint peeling off after too many applications of bleach .

Vinegar dissipates quite quickly. And its non toxic, a great cleaner, as well as killing biological matter

I spent a few years using 30 seconds mould killer spray and using the dehumidifier more often, but each year it would come back as its a shabby old house. Last year I did the spray, let it dry then repainted with the ceiling paint which claims to be mould resistant.... past 12 months I havent seen a spot of mould anywhere. repainting everything myself worked out cheaper than getting the house treated.

You have to deal with the damp. Killing the mould is justs dealing with a symptom. New mould spores will colonise the area if it stays damp.

Funnily enough I came across Borax by chance at Bunnings. In the weed killing department. Was surprised to see it as I was after some for a long time but was never able to find any.

I use the silicone/grout product they have - and it works very well...much better than anything else I have tried (incl the white vinegar option)...
