Amazon is price matching Bunnings for this WD-40 Silicon lubricant spray. Now my preferred around the home lubricant as it's longer lasting than traditional WD-40 and can be used on most materials being silicon.

Usually around $13.70 but down to $10.40 for this deal. A handy thing for the garage door, hinges, sliding doors, walking mats, any kind of wheel or moving part etc etc. Fantastic product that basically made my garage door completely silent.

Note: Aerosol products may not ship to certain postcodes.

    Does it have the same great taste smell?

      Don't know about smell, but tastes great.

    • iridiumstem on 26/07/2025 - 18:12

      No. That said these have really bad chemically fruity smell that I cannot stand.

      Bambu lab updated their documentation to require WD 40 - the original. https://wiki.bambulab.com/en/a1/maintenance/lubricate-y-axis

      Not this stuff though. Although on paper it should be better

      • ZT on 26/07/2025 - 16:48

        That's good to know… I'd imagine it be suitable for the Bambu A1/A1 mini as it has linear guide rails. Not sure it's relevant for 3d printers in a general sense.

        This silicone spray also leaves a thicker residue than the standard stuff so not sure it'll be better

        • Davo1111 on 26/07/2025 - 18:40

          Not sure it's relevant for 3d printers in a general sense.

          They're a reasonable chunk of the market

          • ZT on 26/07/2025 - 22:21

            @Davo1111: You're on point about the brand, though the A1/A1 Mini are Bambu's only models that use full-metal linear guide rails which are compatible with WD‑40. There's a few other models out that that use linear guide rails, but it's the minority.

            Most other printers, like CoreXY models (P1, X1C) and ones with V‑slot wheels (e.g. Ender 3), don’t use metal guide rails. These systems typically rely on plastic wheels, and applying WD‑40 can damage components or cause debris buildup. In these setups, PTFE spray or light machine oil is far safer.

    Is this good for key holes?

    • JSONBourne on 26/07/2025 - 15:26

      I assume because your key is sticking upon insertion? Is it a new key by any chance?

      • DraggyX on 26/07/2025 - 15:27

        Old keys, just the door lock is playing hard

          That's probably more the pins needing some grease, I'm not sure this would be able to penetrate that far in if used externally. You probably need to remove the lock and access the bins to ensure they're properly lubricated.

        • RogerLoger on 26/07/2025 - 18:17

          A squirt of any silicone-based lube will do the trick and it does not leave a sticky residue. It's also great for sticking zippers.

          https://neptonics.com/blogs/news/silicone-spray-vs-lubricant…
          The WD40 mentioned in the web page above is regular WD-40, not the WD-40 silicone spray in the OP's post. WD-40, the company, make a lot of specialist lubricants. Unfortunately, people confuse the company name as being the WD-40 muli-use product. Like most, they make other products. Their MSDS page contains a list https://wd40.com.au/safety-data-sheets

    • endotherm on 26/07/2025 - 15:30

      Use graphite powder. Liquids tend to gum it up worse by attracting dirt and turning it to a sticky mess. Graphite powder remains dry but slippery.

      • JSONBourne on 26/07/2025 - 15:30
        +2

        Depending on the surface the powder doesn't always adhere correctly no? Sometimes you want some liquid to bind the lubricant to whatever surface it's being applied to.

      • Jimothy Wongingtons on 26/07/2025 - 15:34

        I agree

        Had a stuffed lock which was remedied by wd40 for a few months , but recently I looked again and can really tell the barrel is all gunked up too

      • CheapCookie on 26/07/2025 - 18:53

        I agree with endotherm.
        I used wd40 on a brand new outside lock thinking it would protect it.
        The lock was stuffed in 3 weeks, became almost impossible to open.
        The last straw was when it jammed up for 30 minutes and me trying to open it, and sweating and starting to think I would need to get a lock breaking tool, finally came loose.
        Lesson learned.

      • SparkleWings on 28/07/2025 - 10:17

        Graphite powder is the way to go…….until you/someone sprays some wet lubricant (oil/silicone spray/…) into the lock, from then on stick with liquids. Yes, it gums up over time, but you re-apply regular WD-40

        i've only had to wet lubricate it about once per year when it starts to feel a bit stiff/gummed up, give it a 2-3 second spray right into the keyway with the detail/pipe nozzle, put the key in and out and turn the lock, have paper towel handy to stop any WD-40 that spills/leaks out.

        Edit: you can also try an aerosol dry lube (like a PTFE spray, which can be ok, or the solvents can interact with the dirt/graphite in the lock and gum it up too) - not my preferred approach.

    • rhino86 on 26/07/2025 - 17:33

      For sure, on the suzuki sv650s in the rain, uh crap. Use some compressed air to blow any water out. then use some proper WD40 to help repel some water.
      Not the silicone type in the web link.

      • BrokeQueenslander on 28/07/2025 - 00:03

        oil repels water.

        silicone is handy when you need something inert like breast implants. To lube a chain, I'd still prefer oil.

      One occasion when I found my girlfriends key hole was quite tight when inserting my key, I used a bit of WD-50 silicone lubricant Then thrusted the key in and out of key hole quickly until the lube was well spread. That seemed to do the trick. I found the long nozzle provided good penetration.

      I also did the back door while I was at it, just to be safe.

      My girlfriend was very impressed with the results.

    • DarwinBoy on 26/07/2025 - 21:03

      I've always used graphite powder in locks.
      It works every time.

    • mrderrickc on 27/07/2025 - 00:19

      Better to use graphite powder.

      Grab a HB pencil.

      Colour your key in with multiple layers, powder bits.

      Then whack it in/ out of lock like a teenagers finger on prom night….

    Would this be any good for sunroof tracks?

    • alexdagr8 on 28/07/2025 - 00:19

      Probably better off with a lithium grease but could work in a pinch (depends on how heavy duty your application is)
      Original WD40 is a penetrant (rust remover/ loosening bolts) whereas silicon based is good for lubriating joints/ tracks etc (preventer)

      But ideally use the correct type of grease for the application

  • Mewcarton on 26/07/2025 - 15:47

    longer lasting than traditional WD-40

    that's cos traditional WD40 isn't a lubricant its a water displacer.
    The very thin lubricating oils in WD40 are meant to displace water and coat the surface in a thin moisture barrier to protect it from oxidisation, not to be used as a frictional lubricant.

    Plus it being oil based is not suitable anyway for exposed things because it collects dust. So silicon lubricants like this deal are indeed very good for locks and hinges etc.

    • JSONBourne on 26/07/2025 - 18:12

      Correct, I just put that as most people don’t understand that normal WD-40 isn’t a lubricant

      • Tigersboy on 26/07/2025 - 19:15

        I understand the WD stands for water distributor, and 40 is the 40th iteration of the product (that they then went with).

    I have said it here many times before, Inox MX3 is a far better product, and as a bonus is an Australian product. Doesn't stink, doesn't dry out and gum up, also only a few dollars more.

        If it is, I stand corrected. I thought WD was a USA product. Not that that matters, but it is a little orange coloured when it dries…… Regardless, Inox is better in every way in my opinion.

        • Gav on 26/07/2025 - 16:57

          It's right there on the front. ;) All good, probably parent company is (possibly same for Inox). I thought only original WD40 had drying issues, but not enough experience with both products.

          • revheadgl on 26/07/2025 - 16:59

            @Gav: All good. Been using Inox for a very long time and it really is a good product.

      I bought this to lubricate the rams on my gate openers and it’s worked a treat. Several dollars less than WD-40 and the only difference I can tell is you need to fit the straw yourself if needed, unlike WD-40 where you simply flip it up.

      This aerosol stuff will just disappear after a while.

      An alternate I tried is motor oil, which does the job and doesn't require re-application frequently.

      Designed for heavy industrial, mining, farming, marine, earth moving and transport type use and where extreme climatic and high humidity conditions prevail.

    Inox is the way to go guys. Try it once, you won't go back to WD40.

    • n3ck3ntry8bort0rgasm on 26/07/2025 - 20:23

      yuh might try inox next time if it's not too pricey.

      whenever you have that squeaky thingamajig that doesn't go.
      I'm thinking MX4 which I mentioned above will be like one quick spray and good for almost 10 years.

      tbh WD40 was like one quick spray and good for 2 years so.. can is rusting with no pressure before I even used half of it.

  • tongheitai on 26/07/2025 - 20:46
