    For rust removal I have been experimenting with electrolysis.
    It worked really well on cleaning up a machete I have been restoring.
    The first pic is when it started and the second pic shows how much junk it drew off the metal

    It really comes into its own on stuff that's delicate or you don't want to risk with acids or abrasion from sandpaper, wire brushes etc. Usually I degrease parts with a solvent, clean away dirt and coarse rust with a plastic brush and scraper, then toss everything in a bucket of the stuff for a day giving it a stir a few times. Usually that's enough, though I've left an old percussion barrel with seized plug in it for months and the plug came free at the end. Parts come out grey with a soap film to stop flash rusting when drying. The soap is water soluble so can be washed off when it comes time for surface prep. The solution weakens with time and use, but it's not a big deal in the grande scheme of things.

    Also helps that it doesn't give you headaches, can't eat your skin/eyes/tools, light on fire, or destroy your parts if you leave them in there

    I use it to derust old car bits, a bit spendy but does a good job and isn’t as toxic as other stuff.

    For those with access to it you can use a 1:2 mixture of molasses to water to safely derust stuff, takes a wee while but it does work and again not toxic.

    It's just an old thing a client dropped off years ago !
    I think he's dead !
    Or he's forgotten he even owns it

    But it had without doubt the ugliest fore end I have ever seen and it had huge vice Mark's in the wood

    My two per hates.
    People putting gun parts in engineers vice without jaw protectors
    People buffing firearm parts ... especially actions and octagonal barrels

    It's just baking soda, a dash of vinegar and then I just ran it off one of my 18v makita batteries used hardly any of the battery charge ran for a few hours.
    I did sandblast it first to get rid of the worst rust

    Could you use an automotive trickle charger or do they not like that sort of thing?

    I have a tank setup, square with rebar in each corner.
    Just use old laptop power supplies, ranging from 16v - 19v and 4-6amps.
    Seems to do the job.
    If there is something really delicate, I use a vat of vinegar.

    I do a lot of old tool restoration so have investigated it quite a bit. Some of the more intellectual rattle on about hydrogen embrittlement caused by electrolysis, so when it comes to axe heads or anything that will take a heavy smacking I defer to the vinegar

    That's a great idea about the laptop charger. I may have a couple of them floating around from the old dead ones.

    Cell phone chargers work well - low voltage low amperage kinds. Probably will rub someone the wrong way saying that, but does work.

    Also nice because it won't get too aggressive and start eroding the good metal too quickly.

    Having a residual current device/RCD is a good idea as well... less likelihood of electrocution

    I doubt anyone would admit to owning a rifle with a fore end that ugly

    He might come out of the closet when this is complete
