32 sun visor ?

Watched a few videos on rust removers. Vinegar , muratic acid, hydrochloric acid, ect.
Since I have some here and it's free I'll try vinegar.
We use it to clean out our Jacuzzi tub. PITA to clean that thing.

If you have a chance search the Molasses and water method online.   Slow but it works...tried it on a small scale.

Well after a vinegar bath and wire brushin , it revealed a cool patina that shows a bit of it's former past. I cant seem to part with that right now. So I'll lightly sand it to get rid of sharp edges and clear coat it.

Citric acid is cheap, non toxic, and you can get it at the grocery store. It will remove ALL of the rust and won't hurt plating or paint.

Looks pretty cool!

 Looks much better.. I use vinegar on light rusted parts. Just takes time.. As sixball says citric acid works very well also. Ron

I was digging through my stuff today and found the visor that goes with the top on my 33 Cabriolet.  The first two pics are the visor (second one folded).  The third is the front bow of my top.  You can see the mounting locations for the visor.

Found a good video on rust removers.

Stopping at the home depot . I found these two.
I bought the cheaper one. It says it contains Phosphoric acid. Probably a bit heavy for what im doing.
Note;;;; when asking about acids, you get some strange looks. Couldn't find citric or oxalic acid (molassis) here in the city. Oh well.

Anyways I'll give it a shot and then it's time to make the visor itself.

My neighbor gave me a collection of milling bits today, they had a good amount of rust.  So a short time ago I bought some apple cider vinegar and have the parts soaking in it tonight.  I'll report back in a day or so.

You can find food grade citric acid at the grocery store. It is completely safe and can be disposed of in your yard. Citric acid is edible and rust is just iron and oxygen. You have to get the oil and grease off and it won't harm paint or other metals except zinc (galvanize). It works fast as well.

Wish I would have taken a before picture of the misc milling bits my neighbor gave me..they were rusty and dirty.  Thought for sure I would be spending some time on the wire brush.  So I soaked them overnight in apple cider vinegar...the next day the solution was dark and the bits had rust removed in spotty patches.  Vinegar was working.

Recently bought a 6L ultrasonic cleaner ($108 shipped eBay) so I put the bits in the ultrasonic cleaner with straight apple cider vinegar for 30 minutes.  Had to rinse them off with hot soapy water, let them dry and put on a light coat of chain oil.  Did not wire brush them or wipe them individually...they look really nice!  Now I can go through them to separate the good and bad.

Very nice! It is crazy that we have all spent hours and hours with wire brushes and wire wheels within a few feet of a jug of vinegar. 

I have a large case cleaner for cleaning used brass ammo cases, probably 3 gallons. I've used it for light cleaning of small parts and polishing. I bet a 1/2 gallon of vinegar or citric acid solution would really remove rust if it didn't slop over the edge. The citric acid smells better.

Well for me the rust removers didn't work out.
It had phosphoric acid and nothing after hours of soaking.
Ended up using the wire wheel and sanding the arm it was so pitted.

I have a Lyman 1200 (vintage) vibrator style case cleaner that uses corn cob media etc.  Works fine on brass casings. Heard about the new technique of using stainless steel pins to clean cases...but you need to use the SS pins in rotary tumblers not vibrator cleaners.

We'll see. I have a bunch of small rusty things to clean. Nothing to lose.
