Anyways, speaking of cool metal related tips and tricks, does anyone have a good way to remove rust and corrosion from nuts and bolts, or large pieces like car body panels - in case you do want to finally take a chance at fixing up that '68 Chevy Engine that is sitting in your living room - (or '79 Mopar 360 as it may be in my case).

I was thinking just buying a cheap barrel tumbling kit from the craft department of the local store for the nuts and bolts, but will that work?

Is there a chemical way to remove rust and corrosion that would be faster, or easier - more for the bigger parts that won't fit in a tumbler?

I don't mind using a little (or a lot) of elbow grease, but if I can just let things get clean overnight in a solution of whatever, or in a barell tumbler, then that would be great.
You can still find places that "Hot Tank" parts for you - which depending on your part is either an acid bath or caustic. I had an engine block done about a month ago. Saw an episode of "Overhaulin" wher they acid dipped an entire car. Galvanizing places usually have a huge hot tank.
For home use there is Naval Jelly - been around for years and works pretty well. For bolts and small parts I use a grinder and a wire wheel, these throw off the bristles pretty well so make sure you wear a face shield.
But the best is a sandblast cabinet and is enviromentally friendly.
Word of caution when using chemicals of any kind. Make sure you know the hazards before you proceed. Look up the MSDS for that material on the internet or find an expert ( and then check the expert to make sure they told you right). Acid and Bases can create strong exothermic(heat releasing) reactions.
