Really really cheap ways to remove rust?

[TireTracks]

I found a rusty old dado stack under my new table saw, and i'd like to clean them up to use.

Would vinigar remove the rust? I'm looking for the cheapest way to do it.

Got a battery charger?

Afford $7 worth of jasco from lowes paint section?

plastic bowl, baking soda, water,battery charger ,or wall pack charger from discarded electronic device, do a google search to find proper way to hook up the electricity +/-(I can never remember proper way lol) will remove rust,grime etc. you probably have all these already no $ expenditure

If you can find feed molasses (for animals), that works very well too. But it'll take a longer time, about a week or two. But the advantage is it doesn't require line of sight to work, and you don't have a lot of hooking up to do.

mount it in the table saw turn it on and get the angle grinder with a wire cup brush

seriously dont or if you do setup a video camera to record it and put instructions to upload in your will

Vinegar would work fine. How long you leave them in the vinegar is dependent on how much rust is on them, so you will have to do some experimenting. If the rust isn't very bad, you might just leave them in for a day and see how that works.

Thanks.

I'll have to do this, dont really want to deal with electrolosis right now.

$2 bottle of white vinigar and a bowl ,wait bout a day or less depends on how bad the rust is then justscrub with a wire brush then give a light coat of oil

I've used electrolysis, vinegar, and even the severely under rated wire wheel.

In this case, I would definitely suggest the vinegar.

1) the seriously underrated wire wheel, with the blade on the bench!

2) a few oz. of auto trans fluid and a scotchbrite pad. This works amazingly well.

I soaked some bolts in vinegar overnight not long ago. After the soak the threads had changed...the were "knifed"..and the nuts that went on them were loose. I asked about this on another forum and was told vinegar has a "pickling" affect that caused it. If it were me...I would not use vinegar on a table saw blade that possibly has welded on tips..... Evaporust is the best solution IMHO...

Evapo-Rust, while it was some disadvantages (somewhat costly, hard to do large items, mild staining can rarely occur with certain finishes) is definetly the best rust remover to use for tools. It's very forgiving, about the worst thing you can do is not soak something long enough or mildly stain something. If it spills or splashes on something, there will likely be no damage. Acids, vinegar, pastes etc are all inferior imo.

To see how good Evapo-Rust works check out http://www.garagejournal.com/forum/showthread.php?t=95365 and my 80 year old "eggbeater" ratchet. When I got it, it looked like rusty scrap and the chuck was seized up with rust, now it looks almost as good as new and works even better. Please note that the goldish color is not rust or staining, it's a coating of motor oil I put on, which my camera always seems emphasize.

It doesn't work (I meant the potatoes). The only few non-mechanical methods I know which work well (and are worth the time) are:

1) Electrolysis
2) Feed Molasses
3) Acid
4) Chellating agents sold in various commercial brands
