    Still think white King is more effective

    • +4

      Probably just as effective, but definitely more cost effective as mould killer is essentially just dilute Bleach

      • +13

        In general, bleach doesn't kill mould. It bleaches it.
        From memory oil of cloves is the best remover of mould. Google Shannon Lush if you want details.

          In general, bleach doesn't kill mould. It bleaches it.

          Bleach kills mould, but only surface mould. It won't kill what's growing underneath the surface of grout for example.

        • memory oil of cloves is the best remover of mould

          It might be but her suggestions for other cleaners aren't great eg white vinegar.

        • +3

          Possumbly, no disrespect intended, but I read the article you linked. It's utter garbage scientifically. On the one hand, bleach is ineffective 'cos it supposedly can't penetrate porous surfaces (unlike water, for instance, which is the medium for mould growth)….on the other hand, it's useless 'cos it is composed of 90% water!! So, which is it?
          If the bleach you buy in concentrate form is 90% water - but that ain't "penetrative" enough, then just dilute it more with water….THAT's exactly what the prepackages specialised mould killer manufacturers have done - and they charge you for the privilege!!
          Me? I'm happy with 90% water content (or whatever), and I'll just keep using my HIGHLY effective cheapo Aldi bleach to kill mould. Works brilliantly.

          • @Ozcelt: Only perused bits of the article myself Ozcelt. It's mostly on the ball. Nearly all the specialist mould "killing" bleaches have the same or very similar active ingredients to straight bleach. I also now use Aldi Force Pro, which is thicker, more alkaline and cheaper than the above specialist stuff.

            Have used bleach and vinegar many times to try and kill mould in old grouting, in silicon filled gaps, and on crazed ceramics in the bathroom. Worked brilliantly to the naked eye, except it didn't. As I subsequently found out it - and as that and many other articles will tell you - the bleach primarily discoloured the mould (probably killed some) because the spores are [often] deeply ingrained. Ergo it comes back. I tried leaving the bleach on for hours with the window open and door shut. Same result. Mould returns. It's not a huge issue but is unsightly. Only a reno will really fix it, at the moment I just manage it.

              @DisabledUser67242: I have a stone wall in my unit. It gets rising damp and mould something chronic. So bad in fact that mould grows on organic surfaces over three metres away. I tried cloves and vinegar so many times and it never worked. For years I tried this. Then I bought the Aldi stuff, sprayed it on twice and left it. It killed the mould instantly. Even the mould smell has gone. From what I know the Aldi stuff had bleach plus two other chemical ingredients plus water. For me it worked.

      • +3

        Probably just as effective, but definitely more cost effective as mould killer is essentially just dilute Bleach

        Cheap bleach is actually more concentrated than this. This cleaner, and bleach, will decompse over time so old bleach (or old Selleys) won't clean as well.

  • +4

    Last time i saw this deal someone recommended the Aldi stuff, it’s amazing. I think it’s cheaper too

    • +7

      So the aldi stuff is amazing?

    • +10

      Completely different product for a different job.

    • +8

      Earth Choice dishwashing liquid is rubbish! Different product but it’s a waste of time!

      • +3

        It works well for me. Only need to use a tiny amount as well.

        • +2

          Works well for me also

      • I find it's okay when new but the contents lose potent when it gets to 30% full.

  • +9

    Anyone confirm if we can use this in place of toilet paper? #desperatetimes

    In all seriousness we use this at home and it's brilliant, spray on leave and water off easy.

    • +4

      Bleach on your butt? You going for a New career path?

      • +6

        The MJ path. Ow!

  • This thing works. So effective that sometime it makes me wonder how corrosive it is….

  • +2

    Coles Ultra Mould is the same price and works really well, plus is also highly recommended by choice for cleaning soap scum too.

    • +3

      For soap scum in the shower recess, noting beats 000 steel wool. Rub it over when dry.

      • Interesting… where you one get '000' steel wool?

        • +9

          Dial 000 on your phone and when the voice asks “Police, ambulance or fire?”, you answer: “steel wool”

        • +2

          Steel wool is steel wool. 000 is just the grade of how fine the wool is, 000 is pretty fine but it goes to 0000 I think?

    • Same product, same amount of active ingredients.

      Both great. But will solidify on the bottom and clog the sprayer in no time. Need to give it a good shake at least once per week.

  • +1

    will it disinfect my hands?

  • I tried to remove mould with dishwashing liquid and brush, but it’s almost like it’s stained in seal of tile… would this fix?

    • For $3 give it a crack and see.

    • This is the best product for that.

    • It should absolutely remove the surface mould, yes.

  • +9

    This cleaner is literally bleach plus a preservative.

    The ingredients are 40g/L sodium hypochlorite (the bleach), and 12g/L sodium hydroxide (slows down the decomposition of sodium hypochlorite).

    The active ingredient in cheap bleach is 42g/L sodium hypochlorite - even more concentrated than the Selleys one. It should also have about 9g/L of sodium hydroxide.

    You can also get bleach with a thicker consistency which would make it stay on vertical surfaces for longer.

    • +1

      I used "toilet paper" to make it stay on vertical surfaces… but now…

    • will either of this remove blackened mould growing on the silicon sealants?

      • +1

        If it's inside the sealant, it won't. You might have to reapply the sealant.

        • +1

          Yep, dig it out, clean the gap with bleach/vinegar/…, let it dry, the apply new silicon. Straightforward job. Too late now but summer is an ideal time.

          • @DisabledUser67242: Why can't I do it during autumn/winter?

            • +1

              @skillet: Sorry, poor wording there skillet. Of course you can. Basically the drier the environment the better. Use a hair dryer to remove moisture in the gap, otherwise you may be trapping moisture and eventually mould may form/return. Not a big deal but obviously the drier the better.

              • @DisabledUser67242:

                Basically the drier the environment the better.

                But summer is the most humid time of year. Winter is the driest.
                Summer is also when I would be sweating all over the tiles. :)

                • @eug: That depends on where you live - OBVIOUSLY. We've just come through a very dry summer with some extreme temps. Great DRYING conditions. The clue for big sweaters is to try not to drip into the cavity you've just cleared. Ditto for those who can't hold back their urine and people with a tendency to dribble profusely (eg politicians and SKY political commentators).

    • This cleaner is literally bleach plus a preservative

      You can buy sodium hypochlorite about 10,000 times cheaper by buying "pool shock".

      Sodium hydroxide breaks down proteins apparently so I guess it's breaking up the mould.

      • +2

        You can buy sodium hypochlorite about 10,000 times cheaper by buying "pool shock".

        Pool shock is calcium hypochlorite. It is certainly cheaper than buying bleach, but I imagine most people, unless they had massive bathrooms with serious mould problems, don't mind paying $1.20 for 2L rather than buying rather corrosive calcium hypochlorite crystals and making sure they dilute it properly.

  • Thanks all for the mould killing knowledge. I definitely want to learn more

  • +7

    What about vinegar?
    Loads of sites recommend it over bleach as it kills the mould completely

    • +3

      I tried it on mine. Didn't work. I had mould like it was stained inside the grout. Straight up bleach didnt work either. Anything else to try?

      • Did you spray straight vinegar and leave it for some time?

        • +1

          I diluted it like the internet said lol but after 40mins and having the entire bathroom smell like vinegar, nothing has changed :/

          • +2

            @jussie2000: make "tubes" of kitchen/paper towel and run them along the grout/silicone where the mould is, then spray with your selected liquid so that the paper towel is nice and wet, press it in so it sticks as well. then leave it 1-2 hours should be enough. normally it will just run off so you don't get the desired effect.


            he uses TP…haha!

          • @jussie2000: You probably killed the mold, but didn't remove it, so it would have looked no different.
            Apparently, the mold feeds on the vinegar and swells up and bursts (if you watch it under a microscope). The bleach products turn the mold white and maybe kill a bit of the surface layer. Which product you use depends on what you're trying to achieve.

            A water, vinegar, detergent mix sticks to the surface better, so that the mold feeds for longer if you're going that route.

      • If it's too deep, you need to scrape it out and redo the grout.

        • Any tips on redoing the grout?

      • +1

        Use this first, leave overnight, then vinegar second to kill the spores.

        • So u reckon this product overnight then vinegar straight up? Do I scrub before applying the vinegar?

          • @jussie2000: Scrubing isn't going to hurt. But this is a great lazy man's/ woman's product.

    • +6

      This is a myth perpetuated by big vinegar

      • +1

        The only thing I found that vinegar works really well as is a fabric softener.

        As a cleaner it leaves much to be desired.

        • I swear by vinegar in the laundry. Rest of the house thinks I'm crazy.

        • Read Shannon Lush. Most of her advice is based on knowledge and experience. Diluted vinegar is perfect for removing cat pee from your down sleeping bag for example.

  • will this work on plaster (on my ceiling)? There's no mention of it on the bottle

    • Same, was thinking of using this on my ceiling. Anyone tried it before?

  • +2

    For those that use these mould killer with a trigger bottle, do you normally run into issues where the trigger stopped working after a while? I’ve got so many half used bottles.

    • +2

      Yup, the trigger dies before I can finish it

    • +1

      Yes, the triggers are rubbish and they fail because the bleach dissolves the plastic. If you call the manufacturer they might send you some replacement triggers. That was my experience when I called whoever makes Exit Mould.

  • +6

    I love how OzBargain goes full circle every now and then.

    "Cleaners like Exit Mould are the bomb" +44

    "Nah, Exit Mould won the CHOICE Shonky award in 2012 for just bleaching the colour out of mould" +178

    "Exit Mould and similar products are just plain magic, amirite!?" +52

    "Nah, it actually doesn't kill the mould apparently. Just removes the colour or something." +144

    "Selley's bathroom mould killer is OzBargain's favourite. Get it while it's hot!" +50

    "Nah, doesn't actually kill as much as it seems." +5

  • People I just read on an article by drinking this thing to will prevent and cure coronavirus! waiting for natural selection to do its thing

    • The article i read said drinking pure bleach is way more effective. Not this dilluted stuff.

  • +1

    Anyone got any tips for ceiling mould? Been using vinegar but not 100% happy.

    • +1

      Wear sunglasses while spraying this on the roof so it doesn't get in your eyes!

      • +1

        Better still, wear protective goggles so you don't get corrosive mould cleaner on your sunnies.

    • Use something like this (or the coles/aldi equivalent). Open the windows or fan and let it dry completely. Repaint with a bathroom/kitchen ceiling paint that's mould resistant. With a good ceiling paint you shouldn't be getting any mould at all, unless there's 0 air flow, in that case you need to get some air into the room via fan/door/window opening etc.

    Just in case you are interested in what has to say about these bathroom cleaners (Update 17 October 2019)

    Selleys ranked 18th out of 33 products reviewed with top places going to:

    Coles Ultra Bathroom Foam (90%)
    Dettol Healthy Clean Bathroom (90%)
    Bosisto's Bathroom and Shower Cleaner (88%)
    OzKleen Mould Power Amazing Mould Killer (87%)
    White King Multi Surface Bathroom Cleaner Ocean Breeze (87%)
    Coles Ultra Mould Killer (83%)
    Selleys Rapid Mould Killer (64%)

    • They're general bathroom cleaners, not necessarily mould cleaners (although they are included in the mix). Also, have a read of their Shonky awards.

      • I'm assuming that the Coles Ultra Mould Killer has improved if Choice gave it a Shonky award in 2012 but listed it a score of 83% (6th place) as of October 2019 in the updated reviews.

  • I've had a few mould issues and i found the Dettol mould cleaner to be the best of them after trying this one and bleach/vinegar combo
