Default Need to soak nuts

Sorry, couldn't resist.... She's at the autobody shop getting a fresh coat of paint.

I've removed the rear bumper and various trim parts(lights, brackets, sills, rocker panels, etc.) and have lots of old and rust coated nuts & bolts. I'm planning on replacing some but most just need to be cleaned up.

1) What is the best solvent/cleaner for rusted pieces and parts?

2) All lights(side running and license plate) copper connectors are green or black. I hit them with DeOxit without much effect. I'm ready to hit them with emery cloth but was wondering if there is a chemical treatment that might be better.

Thanks

the deoxit will remove the corrosion in the metal in a few hours,
the rusted hardware will need a replating or replacement

Thanks. I was hoping for some type of rust buster recommendation. Eastwood has a bunch of products with great claims. I usually just fall back to wire wheel brush. These parts are small and will require some knuckle abrasions and projectiles before they're cleaned up.

Default Evaporust

I'm refreshing the parking brake mechanisms on both sides and had good results this week with Evaporust, which claims to be non-toxic and biodegradable.

All I know is that after soaking some pretty crudded up parts for a day they came clean with a rinse and very light dremel work.

I didn't do before/after, but here are the now clean pieces sitting next to the still dirty shoes (. . . which were worn down to bare metal; new shoes on the way).




Pretty easy -- soak and shine.

Somewhere there's a thread by a guy who used CLR to soak his CE panel and other items. I can't find it, but he didn't damage anything, iirc.

So maybe CLR? Couldn't hurt to try.

Default CLR on CE

I think that was U-boat Commander on Pelican.

Tsk tsk ... you are being a very naughty boy, talking about your car's ********* in such a flippant manner.

I've had to soak them one or twice in my life ......or was that a blue ointment...... I forget; but IIRC a combination of acetone and something else (maybe power steering fluid? - I forget again) blows the hell out of PB Blaster and all the other rust removers that are used and typically bought at stores and is cheap besides. I'm sure one of the other old guys with better memories will chime in here with the formula.

Use pink eraser for the copper connects, then coat with deoxit to prevent further oxidation. Did this to all relay tabs, and worked wonders! Makes it look brand new!

Right, half and half, but it's a penetrating oil, not a rust remover. If it does both that'd be a great bonus.

Good on Gearloose for remembering U-boat Commander. Got it in one AND posted the link.

Evaporust looks great.
