  • Molasses, Evapo-Rust, Muriatic Acid, White Vinegar, Organic Apple Cider Vinegar, and water (control) compared for rust removal. All of the products were tested over 3 weeks. 5 separate tests were conducted to assess performance, including 2 separate tests on rusty metal, metal flakes (corrosion test), painted metal, and aluminum. Before and after weights of metals helped to determine rust removal and corrosion risks. Muriatic acid is fast but aggressive rusting happens after using it. Evaporust works extremely well and doesn't seem to harm metal. Molasses is slower than Evaporust but seems just as good if used for 3 weeks. Both white vinegar and apple cider vinegar did very well but seem to eat away good metal too. A lot of viewers requested this video--so, thank you and please keep the recommendations coming!

    I would never have expected molasses to work. Fact is I thought perhaps someone was pulling your leg. I stand corrected!

    I wonder if slightly warming up molasses would speed up the process?

    The trick with evapo rust is to dilute it 50% and heat it up. It takes the reaction from taking days to minutes.

    Great video. Rust removal is something we all have to deal with. Even here in Southern CA.



    An idea - can you test which gas tank sealant works the best. I've heard a lot of good things about POR15, but I've never used it.


    Thanks again.

    Kerosene works the best bar none. We use to use it on our bolts when I worked iron. Over night and your rusty bolts are lile new. It loosens rusty nuts. And will eat rust like no other that I have seen. But thats my opinion amd opinions are like assholes everyone has one. So take it as you will

    Oh well.
    There is no such thing as mollasses.
    There is mollasses, blackstrap molasses, &sulphur or unsulphured mollasses. Which is best &why?
    Blackstrap is what I eat. Female weightlifters take it. Great 4garden plants growth, insecticide.
    5 gallons with free quality bucket Websteraunt $26.
    Mollasses is also the original flavor God gave sugar so is great additive 4artificial sweeteners. It's what makes white sugar brown sugar.
    Satan removed all the beneficial properties from sugar &salt &flour etc. Making them poison. If u think these processed by Reptilian angels foods aren't poison next time u go Walmart see how many people u estimate could manage jogging even1 time around the building.
    This video effort was still great 4starters. I wonder which property in mollasses accounts 4thrust removal. Mollasses contains a lot of "fine plant grain" minerals which can then absorb on a cellular level. It may be it's just viscous permeating medium.
    There is no such thing as rust lol. Rust has been engineered in by backstabber engineers led by Reptilian angels. Like, plastics that sunlight dissolves.
    Some tools are not available 2public. Example I have a 4' iron rod that is incredibly superior simple virtue of it won't flex or ever rust. It is commercial &Reptilians do most all the construction there.
    Those blue 55gallon drums, banned from public use originally. Thankfully they are seeing use otherwise. They are incredible lifetime tools the public isn't supposed 2have.

    I've always wondered about this magical evaporust that (hand tool rescue) uses. And really, molasses?! Thats new to me

  • Dirty Bird

    Definitely surprised by the molasses, I never heard of that little trick, but now I know for the next rusty job. Evaporust honestly really is good, I've used it multiple times but seeing the comparison and little experiments showed it. Most stuff your going to be removing rust from is probably something that you aren't worried about losing paint or coating anyway so

      Do you think mixing apple cider vinegar and petroleum jelly would work well as a paint remover? Someone painted all the crome trim on my project car and its been tough to remove without scratching..

        wow. I wish I knew this before.
        I used to work on fire hydrants, there was some old ones that had frozen valves. its was impossible to remove because of rust in the bottom. we try coke. did not work. I don't remember other things we did. but as last muriatic acid did the job in a hour time. never try vinegar.

        This may have been asked already, but from a novice eye, 8:34 molasses vs white vinegar: The white vinegar looks like it has gone much deeper into the threads. Maybe I misunderstood the experiment, which is totally possible.

        I picked up some black walnuts out of the backyard, stuck them in a 5 gallon bucket with water for 2 weeks. Most still had the husk on. I put a rusty trap in the mix, checked it 24 hours later and most of the rust had been removed. How would the rust be removed?

        Phosphoric acid is the best because it not only removes it stops rust

          Your analysis was very precise and meticulous.. However, you chose to compare rust removal by just soaking.. That is not a valid measure. Rust removers can be seen like paint remover. If you only brush on paint remover and leave it, the paint will not be removed. These product are not really removers, but SOFTENERS. I use rust remover a lot to restore old tools. All of these products should only be used for 24-48 hours max. After 24 hours, a true test would be using plastic, brass or steel bristle brushes, and then washing in water and drying.. If it did not all come off, then another 24 hours and then brushing them. I would guess that all of the products will work in 1 day.... NOT 2 WEEKS!!!! That would destroy all the steel...

          My father had some pink slime stuff for rust removal. It worked amazing.
          Unfortunately I don't know what the product was. It was in the 1980's.
          Anybody have any idea what the product is called?

                Looking to give this a try on rusty sections of our boat trailer, however most replies say to dip and keep submerged. I wonder what sort of results we will achieve by spraying on and if we should have a stronger mix for a spray. Any ideas on what ratio to try? Cheers PF for putting us on to a chemical free option, much appreciated.

                  I’m going to show this to the City! I want them to put molasses on the roads in the summer, it even matches the colour and it’ll clean the rust from the winter salt right off my car. It’s a sweet idea don’t you think?

                    Growing up in a farm community, we used to take a large garbage can, fill it with water and 5 gallons of molasses. Which you got from the ten gallon tank at the feed store, bring your on container, for about $3. We would just throw anything that needed rust removed in the can and fish it out a month later. When the molasses had finished its usefulness, it would get turned into the garden soil. 100% recycled. Cannot say one way or another if this was a good idea or a bad one, but you got to love the ingenuity and the practically.

                    If you need the job done fast Muriatic acid. If you have time apple cider vinegar and molasses. I'm a big Naval Jelly fan (phosphoric acid)

                    I learned about muriatic acid from my grandfather who worked on the RR. They used to use it to test RR spikes and tie plates to see if they could be cleaned and re-used, after old track lines were torn up and replaced. I don't recall how long they let them soak, but often times there wasn't much left of the old steel after the process. He used to bring some of the acid home for home projects in glass bottles with special lids. As you say, PF, the acid would evaporate within a couple days if left exposed. BTW, I don't recall the concentration... Good video. I suspect that molasses will keep my guts from rusting :)

                    I've never seen someone water down muriatic acid or molasses for rust removal. Have always seen people, myself included, use both muriatic acid and molasses straight.

                      One trick I've learned is to mix 50/50 of 20% vinegar and molasses, apply in a thin layer on whatever surface you want to take care of, place a plastic sheet on top to keep the vinegar wet, and let sit overnight. When it comes to surface rust, it can take care of most rust application within a solid 24 hours. When it comes to heavy surface rust, a solid 48 and you should be good to go.
