    Default DIY Penetrating Oil.

    I've been trying to get a muffler off an old Kohler 25hp. Soaked the nuts for five days with various things and only got a couple to budge and I was a bit scared of breaking the studs, they were pretty rusty. A guy at Rayco where I bought the new gaskets told me to try Wurth Rost Off. While trying to find someone around here that sells it I came across this forum thread. http://www.aulro.com/afvb/technical-...omparison.html

    Thought I'd give it a shot, the nuts wouldn't budge. Twenty minutes later, Off in a flash.

    Some of you probably know about it already but it amazed me, and that doesn't happen very often. And it's super cheap, if you have someone around that uses nail polish remover. I don't use it, but I did have some for taking old rego labels off. We don't have them anymore.

    50/50 Auto transmission oil and Acetone, mix it well and only about as much as you need at a time. I just used a very small paint brush to put it on, didn't need much.

    Great tip. Got a gallon of acetone, I'll have to try it.

    From that link, might interest you if you don't know about it already.

    With the addition of equal parts of Mineral turps and Kero, it is also a military grade gun cleaner, known as Ed's Red.

    I looked up Ed's Red. http://www.lasc.us/EdsRedBoreCleaner.htm

    Thanks for finding this stuff.
    Interesting how a limited gene pool and a limited labor force seem to be so closely related.

    Great tip. Gonna write this down for the mechanic. Although the guys I work for break stuff before it can rust.

    it works but the acetone seperates from the tranny fluid if it sits a while .

    Candle/Paraffin wax works good if it's a fastener that can be heated.
