    Default Rusty chain

    I got a pretty good chain hoist. It lives outside under the eave. Itís a permanent install and has been hanging for a year or two.

    The load chain is doing fine outdoors. But the pull chain is not happy. Pretty rusty. Iíd rather not grease it. I tried to get a galvanized chain but it was not available.

    I was thinking about a product called Chem Black Star rust converter. Seems like it would be less likely to flake off and gum up the works than paint. Though even paint causing a problem doesnít seem too likely, though Iím just guessing.

    Getting to the thing is a bit of an ordeal so Iíd rather let it rust than mess it up.

    This rusty pic from the product website is pretty accurate re my chain.

    What says the hive mind? Iím open to other ideas.

    Simpler is better, except when complicated looks really cool.

    I've used this on rusty parts of my boat trailer and it does a decent job; I re-apply once every couple of years. But I'm wondering what made the chain so rusty, or maybe you are closer to the salt water than I thought? I'm about 1/2 mile inland from Puget Sound and rarely get rust on bare steel tools.

    It’s not a high rust area. No salt. Just heat and precious little rain. I think it’s just the steel they used for the pull chain. Other stuff I leave outside barely rusts over years. And thanks!

    That's a high quality chain rated for overhead lifting, looks like BBB chain
    Any other chain you may have is likely to be plated, and not rated for overhead lifting (hydrogen embrittlement)

    I would try the rust convertor and avoid oils and etc. I hate a sticky, slimy, gritty, rusty chain fall...

    I'd spray Squirrel Piss on it and brush away the worst of the scale.

    Pick stuff up and put it down in the same place, over and over. Productive use of your time- like body builders

    You could just leave it, since the existing protective layer of rust will slow down further rust. Just kidding...sorta. But isn't that the way cor-ten steel works?

    You'll probably die of old age before the rust eats through enough steel to be a danger. And it looks kinda cool, like old barn-ish. And it is just the pull chain.

    If you need any other expert advice just give me a holler.

    Rust on the chain can be a real pain Jack. I have a hoist hanging from a tree that I use to haul up sheep when I skin and gut them. When there's rust on the chain it's impossible to dress a carcass without it getting dirty marks on the body, and they take a lot of work to remove. The rust gets into the grease on your hands and the chain swinging round after being handled leaves brown marks on everything it touches. Nobody likes a leg of lamb with dirty hand prints on it JayInOz

    There are two kinds of lubricants for bicycle chain - oil based and wachs based. Perhaps the wachs based bicylce chain lubricant would do a good job?

    Beyond that - de-rusting with a wire brush and then a coat of thinned down boiled linseed oil?

    Boiled Linseed will do diddley squat, apart from making it sticky.
    I would look around for a galvanizing tank and get the chain dipped.
    It really is quite difficult to build an ugly wooden boat.
