Motortech Brake Cleaner 400g Aerosols - 4 for $10 @ Repco

Four Motortech Brake Cleaner 400g Aerosols Cans for $10 at Repco

Was browsing the online store for something else and this popped up. Usually priced between $6-8 each depending on where and when you buy.

Quoting outlander from a previous post:

For those who don't know, brake cleaner, despite having a very specific name, is actually a multipurpose product. It is generally made up of alcohol and petroleum products with low boiling points. This means you spray it, it carries away the dirt and grease, and then it evaporates. Can be used on just about anything. The guy at the auto store told me he even uses it to clean carpet stains.

Deal expires 7th April 2019 according to their website. Enjoy!

  • Can this be used to clean MAF sensor?

      It's not recommended. I recommend using CRC Mass Air Flow Sensor Cleaner.

      • CRC MAF cleaner is about $28 on Supercheap auto :(

          New MAF sensor costs a lot more :)

      Truth about cleaning MAF sensors is that it puts them on borrowed time.

      A Hot wire maf sensor usually has a coating on it from factory; it's not usually an applied coating per se, it's usually a micro coating of a weather inert material at the time that the wire is manufactured.

      When the MAF gets dirty (specifically oily, is worst) it boils on the wire and leaves deposits and pits; but more importantly it often causes the plating to lift.

      So while a clean MAF is better than a dirty one, any petroleum based cleaner is risky, because it can (depending on the coating) cause more rapid failure (after a few weeks of dramatic improvement, of course).

      If it's purely dust maintenence, you're better off with demineralised water.
      If someone was silly enough to put an Oiled pod on your MAF driven car though, then by all means blast it with solvents.

      That said, all my MAF knowedge comes form Subaru's and Nissans, where the MAF is a delicate beast you can't risk damaging.
      Nissans have a 'fall-back' MAP to rely on, but Subarus will just detonate themselves to hell.

      also; car nerd tip:

      If it's an older subaru (pre blob-eye\Peanut eye), make sure your MAF has a green dot painted on its casing, otherwise it's a known failure point.

      Also, if you have a Z3* based NISSAN MAF, re-solder the contacts under the lid with leaded solder, then apply circuit board lacquer.

      Professional MAF cleaner, or pure Isopropanol is your best bet to NOT damage a 'worn' maf further.

      • Thank you Master - Fist-palm

        • 🤜 🤛

  • I use this to clean circuit boards with spilt liquid (coke, coffee, milk, etc), prior to washing them in demineralised water.

    It's significantly more harsh than 'electronics cleaner' when you have deposits to take care of.

    This deal might be better if you only want a couple of units https://www.repco.com.au/en/brands/repco/repco-brake-cleaner…

  • Thanks OP. I literally just picked up and shook my last can if brake cleaner to find it empty, came in from the workshop to find this! Perfect.

    Thanks, but WD-40 works fine. It made my brakes squeaky clean.

    Disclaimer: I am just kidding, don't try this at home.

    Top marks to Repco. For so long their website was useless….

    This was my first online order and it took just 5 minutes for both a txt and email confirmation of it being ready for pickup.

    Penrith store in this case.

  • Just putting it out there - isopropyl alcohol in a spray can with propellants. But the propellants themselves are a step backwards; or so they say :)

      It's certainly NOT isopropanol.
      I'm sure there's some in there, but it's a mixed 'waste' hydrocarbon blend IMO.

      Isopro doesn't smell, or taste (splashback….) nearly as sweet as this stuff does.
      It also feels much MORE nasty on your skin than isopro does, if you're being too lazy for PPE.
      Isopro just rips the moisture out and feels like you've been handling sand for hours.
      Brake Cleaner feels noticeably hot (though, clearly, the rapid evap means it's the opposite) and only gets 'hotter' if you try and wash it off.

      I have a 20Gal drum of Isopropanol I use for washing down circuit boards, so I'm pretty used to the stuff.

        20 gal! It is very handy stuff.
