There's some black mould on the silicone surrounding the bathtub in my bathroom and I plan on replacing it however I've noticed that some of the black mould is seemingly on the tile itself as shown in the picture below. This means if I just replace the silicone then that mould will still be there.
I've tried removing it with tile cleaner, vinegar, mould remover and it still remains.
Not sure what to do?
Why the neg? This solution might actually work.
Bleach degrades the structure of silicone, making the silicone less effective, more prone to mould in the future and more porous, which means water can get in underneath and possibly pool there, which could result in hidden mould, or water damage.
Thanks for the explanation.
Why the neg on this one!?
@elgrande: No, the explanation is irrelevant to OP's situation since they are replacing the silicone.
Bleach leave the mould there, just makes it look white.
soak some vinegar in a paper towel and then place it along the mould
As with bleach, vinegar degrades the structure of silicone, making the silicone less effective, more prone to mould in the future and more porous, which means water can get in underneath and possibly pool there, which could result in hidden mould, or water damage.
It looks like the silicon has already been removed for replacing. Should be fine if you bleach and rinse, dry properly prior to reapplying the silicon
Clean it with hydrogen peroxide & then go over it with clove oil before resealing once dry.
No. Hydrogen peroxide degrades the structure of silicone, making the silicone less effective, more prone to mould in the future and more porous, which means water can get in underneath and possibly pool there, which could result in hidden mould, or water damage.
No.
Read the OP again.
Then re-read my comment.
Next time: do better! or in Melania speak: Be Best ;)
I used this stuff when moving house to get rid of some stubborn mould, worked a treat - https://www.amazon.com.au/Skylarlife-Remover-Cleaner-Sealant…
Smash the whole tile and if necessary the wall and it is easily removed.
Smashing the tile degrades the structure of silicone, making the silicone less effective, more prone to mould in the future and more porous, which means water can get in underneath and possibly pool there, which could result in hidden mould, or water damage.
Hahaha I'm laughing so hard it hurts
Are you scrubbing hard or just rinsing off the mould remover etc?
Bleach on paper towels, twist them up and place them over the silicone and leave overnight.
I use bleach on my shower tiles/grout and it seems to work wonders. I spray it on with a pump spray. The black mould just disappears in minutes.
But I've also heard that the bleach simpy "discolours" the mould and doesn't kill it. I don't know if that's true or not and I haven't tried anything else.
I think once it's in the silicone you've got about s**t all chance of completely removing it anyway. Fighting mould in the bathroom is a constant battle.
I've used vinegar first to supposedly kill the mould (acid)
then next day used bleach to whiten it
DON'T use them together or immediately after as it may produce deadly chlorine gas.
Chlorine gas degrades the structure of human lungs, making the human lungs less effective, more prone to mould in the future and more porous, which means water can get in underneath and possibly pool there, which could result in hidden mould, or water damage
I can confirm this works
No. Bleach degrades the structure of silicone, making the silicone less effective, more prone to mould in the future and more porous, which means water can get in underneath and possibly pool there, which could result in hidden mould, or water damage.
I had a little read and it seems this is more of an issue with repeated use. I would be using this hack maybe once every 12 months.
Are you sure it is mould?
Have a look at this thread, similar discussions.

Ignore all advice about using bleach or vinegar, as both of them just make it look like the mould is gone, but it hasn’t, and they degrade the structure of silicone, making it more susceptible to mould.
The mould is growing for a reason. Either water is pooling on the silicone, in which case when you redo it, you should aim to have a decent angle to encourage the water to flow off, or your bathroom is not well ventilated. A dehumidifier is the quickest solution for that.
Alternatively, we could just ignore you. 🤷♂️
No, his advice degrades the structure of silicone, making the silicone less effective, more prone to mould in the future and more porous, which means water can get in underneath and possibly pool there, which could result in hidden mould, or water damage.
Or you could actually take the proper advice, he's not wrong and you'll only make it worse by using acids (vinegar etc) or alkaline (bleach etc).
The OP is replacing the silicone, they need to get the mould off the tiles.
It looks like it may have gotten into the gap (water overflow), you'd want to spray bleach so that it get into the crack, then rinse off after about half an hour or so as people have mentioned above. Air dry it for a few days before re-sealing. Not sure if it's just the light, but it looks like there is some paint or silicon running toward the inside of the bath where the remaining mold looks like it sits on the enamel. Grab some nail polish remover or similar and see if whatever it is rubs off, there would need to be something porous on there.
Was a domestic cleaner for a while and the mold/algae in some showers was nuts, but bleach did wonders
I spy the birth of a copypasta
Copypasta degrades the structure of silicone, making the silicone less effective, more prone to mould in the future and more porous, which means water can get in underneath and possibly pool there, which could result in hidden mould, or water damage.
I don't get it, when did OZB become Reddit?
I know, right!
Why replicate a toxic community network on a bargain site? Just hang with the pedditors, if that's your thing.
Reddit degrades the structure of silicone, making the silicone less effective, more prone to mould in the future and more porous, which means water can get in underneath and possibly pool there, which could result in hidden mould, or water damage.
Shannon Lush,the cleaning guru says 1/4 clove oil in 1 litre of water,spray on,leave for 24hrs
Then use vinegar to wipe off the dead mould spores
Doesn’t work - even tried with 5 teaspoons of clove oil
Shannon Lush talks voodoo horseshit half the time.
Sitting in the shower with your legs crossed saying 'Ommmmmmmmmmmmmmmm' over and over while spinning a prayer wheel also helps.
(N.B. It was shown that in 75% of showers, this ritual had no effect at all but in 25% of the cases the mould believed it was dead because of the Placebo effect.)
Hi there OP,
As jjjaar suggested, i did ask a similar question.
I tried everything to get rid of the mould on my silicone.
What i'm going to do is just get it replaced and trying to keep the area less wet.
I'm looking at getting quotes from a tiler who can take out the existing silicone and redo it with a mould resistant silicone.
Hope that helps x
I bought this stuff with very low expectations and completely removed all of it. Only caveat is it comes back after 3-6 months

I'm trying a cheapo UV-C lamp to see how effective that is to kill mould. It doesn't seem as instant as bleaching.
Most black coloured mold is NOT the nasty 'black' mold. If you wakeup dead then it was the nasty type.
Try Selleys Mold Killer from colesworth/bunnings ~$7 per bottle, if this doesn't work get a mold specialist. This stuff is magic.
Isn't this just another bleach (sodium hypochlorite) based solution?
I think it also includes caustic soda (sodium hydroxide)
I remember reading oil of cloves is the best remover. Bossito make some I think.
That’s right. Clove oil in dilute solution kills mould spores. It doesn’t necessarily clean the mould, but it does kill it. I suggest bleach solution to clean, then spray with clove oil solution and leave for 24 hrs to dry.
Although of course that might degrade the structure of the silicone etc…….
Spray with ALDI Power Force Mould Away,
or mould killer at woolies, coles
all gone.
1 litre vinegar plus 1/4 tbsp of clove oil
The clove oil quantity is very important a little more and little less will make it less effective against the mould.
LOL - reminds me of a spruiker grandma last century selling very expensive bottles of hair lotion 'guaranteed' to cure baldness
the only condition was that you massaged it into your scalp for 10 minutes every day - easy, right ?
except … the muscles to raise your arms are some of the bodies most quickly tired, and after even 1 minute your arms become tired, so anyone trying to do that once, let alone every day, is going to fail
so - if it didn't cure your baldness, and you asked for a refund, they could simply say you didn't massage it into your scalp for 10 minutes every day - because nobody can !
Plot twist- get someone else to massage the cream in
If the mould is on the tile it should be simple to remove with a magic eraser or scouring pad.
Possibly mould stick under incomplete removal of silicone- get silicon remover from Bunnings.
I had a similar issue UNDER my bathroom silicon. I took a punt and tried Glassguard Miracle Mould Removal Gel. This stuff is brilliant. It took two applications to get rid of it all, but it’s gone (not just bleached) and hasn’t returned. I highly recommend this product.
Ive used the Bleach and paper towel method before, you have to leave it overnight, and it works extremely well.
Im now hearing a product called Tricleanium from Bunnings works superbly on black mould, im yet to try it as theyve had no stock the last couple of times ive been.
Just noticed they sell it at Mitre10 too

or

Well worth learning how to caulk silicon.
Spend a bit more and get a drip less caulking gun.

In the past I have used Clove oil to remove black mould and that worked a treat.
Try spraying some bleach and wait about 30 mins before rinsing it off.
