Rust removal for the lazy.

[LAGrunthaner]

Thanks to JonL (see his link below) I shopped for Oxalic Acid which I finally found at my small hardware store.

Not sure if I'll paint them later but better than what I had. A few table spoons into hot water then I poured the mix into the pool of water and let it sit. Looking forward trying out a ton of other items.

For cleanup I'll dilute with loads of water and maybe add baking soda.

Thanks to JonL, look halfway through his thread, he saved me ton's on time and energy.

I was unable to find a kiddie pool until my neighbor was tossing one in the trash. Yes super lucky me.

That sure came out nice- but that pool's a bit too much. I wonder if my ass neighbor still has a hard shell on the spare tire of his Rav4?

I also bought some of that powder to try on rusted parts, but it was not soo efficient it seems? maybe the rust was too hard but will try soaking it longer next time:-)

In any case it was for sure a great tip to try out!

Is this method any better or even as good as CLR? Am I the only one that sees rust on that wheel still?

[LAGrunthaner]

Yes I need to do it again.

[LAGrunthaner]

After, you can see the water was not deep enough but I was excited to see the original back side of the wheels really are black. I remember asking what color the inside of the wheel should be recently and saying to myself my wheels aren't black inside.

Not great but zero effort

I'll do another bath deeper for this wheel.

Towel bar before left and after right.

I have more in the bath today and I'll wait 2 days.

Try muriatic acid and your mind will be blown...

Bulli Klinik, I have heard that muriatic acid works on metal too. I've used it on other surfaces and sold it for years in my old fashion hardware store as a teen/20something. Although you have to be much more careful with it. Have you used it on your bus?

This is a great link on a scientific method of muriatic acid.

https://sciencing.com/dissolve-steel-8081019.html

[Bulli Klinik]

I use it all the time. Surface rust comes off in moments. You can also dilute it with water and let parts soak. It will clean severe rust from pitting if you let it soak long enough.

As you said, you need to follow the precautions and be sure not to use it inside. The vapors will rust anything metal. I follow it's use with a typical ospho/phosphoric acid to preserve the metal.

Bulli Klinik, are you saying you use muriatic acid straight out of the bottle directly on rust? I have some large parts that will not fit into the pool can I brush that on full strength? If so how long would I leave it brushed on for say example a large bumper or fender. Then after the wait time I'll assume I hose it off & let dry. Once done how would I put on the Ospho (that new bottle still sits on my shelf) and does it need to be washed off or stays on till paint or spray with oil.

Great pic MrPolak, I love the P for patina.

I haven't had as much luck with CLR perhaps I did something wrong like time or mixture or I'm just too lazy and want a chemical to do all the work. Don't you have to scrub hard with green pads with CLR of which can remove desired patina?

Bulli Klinik, I'll try muriatic acid straight then Ospho perhaps on this muffler which didn't clean up great although may never. I'm not sure if I'll keep it as is or paint with high heat gray. I'm sure it's not that important to paint as it will be hidden behind the bumper.

Note: On these parts I did not remove the previous bath water of oxalic acid I just added fresh, therefore I may experiment on a new batch.
Before on left after on right.

This extra wheel that came with the bus had been repainted as seen on the back image above maybe if it was OG paint it may have cleaned up better. I'll continue soaking the 4 wheels that are on my bus in the upcoming week as I rotate them with my spare it just takes time.
