    Yeah it does work!
    After a couple of weeks in a molasses bath.............



    You'll notice rust on the lower 6" or so. That's because the first time I tried it, my pond liner had a leak and most of the molasses drained out. So, I left it in and it dissolved the rust on the first 6". Got a new liner and flipped the panels over. The rusty part was originally clean but stuck out and was exposed to air. It's only surface rust that'll come off with a light sandblasting (as will the flash rust that begins forming almost immediately).

    First run with the doors (notice no harm to original paint, rubber or pot metal).............



    Built a 4'x4' box out of scrap 2x4's and OSB.............


    Installed a reclaimed pond liner from an old pond in our backyard...............


    Proof positive that an entire '27 Model T roadster will fit in a 4'x4' box..........


    20 gallons of molasses bought at a local feed store for $60 including tax, then mixed with water at a 7:1 ratio - 7 parts water to 1 part molasses............


    Entire car submerged in the brew (until most of it leaked out)!.............


    Replaced the liner, added some more molasses and after a few weeks............wah lah!

    Yes, great idea making the box, thanks for posting. Thats much easier than digging a hole in the back yard. I have heard from severall people that heating up the solution to say 80 or 90 degrees speeds up the process 10 fold.

    Nice! I've done vinegar for smaller stuff, and this Summer I'll be doing big stuff in molasses. (Wanted to do it this Winter, but felt the water mix would freeze) It's great to see another success story. Deer around here smell that molasses and they come double-quick. So if there's animals in the area, make sure they can't get to it.

    It;s just like extra strong sugar soap.iT EATS SOME THINGS THOUGH ;I did some bike chains I probably left em in too long[months] all i found was a bunch of little figure eights in the bottom of the tub the rest was gone really stinks too .dont think you could do it in a residential area.we also used it to free a stuck flathead. taking the part out every day or two and washing the black stuff off speeds the process too.totally safe to use too GOOD SHIT

    For small parts a "crock pot" used one is fine, would not recommend using for food after using it for molasses. Small stuff is much easier to find in the crock pot that bottom of the
  14. Remember the kids science project with the metal left in a glass of Coke, I guess it's the same principal, with a diluted mixture.

    Anyone know if you can use powered and make regular molasses from it. I know a guy with a bunch of dry.
  26. I know a guy that soaks complete flatheads that are stuck. Works great. Just don't use it to make cookies later

    Will it break down oil and grease, or just rust?

    No oil, grease or paint, however some paint may come off if the bond is bad and there is rust under it.

    Do the parts need to be rinsed to neutralize the mixture? Does it leach out from double layer panels at a later date......can it screw up a paint job?
