Hi Folks,
I am putting the front end of my 54 Bel Air back together. The back-side of the front grill is just covered with rust. I mean, it is really bad. No one will ever see it, but I just can't bring myself to put that chrome and stainless back on the car with all of that nasty rust behind it.
My usual way of dealing with rust is to just soak the parts in muriatic acid (dilute hydrochloric acid). But I have never tried it with chrome and stainless steel parts.
Does anyone know what will happen to the chrome/Stainless parts if I get HCl on them?
Thanks
Scott A.

I can't say for sure, because I've not seen it tried, BUT, I would bet dollars to donuts that you WOULD NOT be happy with the results.

Ditto. If it were me, I'd try wire-brushing the loose rust off and then treating the rust with this stuff, and then prime it with Rustoleum Rusty Metal primer and top coat it in satin black.

I have taken 000 alt steel wool and naval jelly and just coated my chrome wheels put the jelly on kind of thick and let it set about every 10-15 minutes hit it with the steel wool and then put another coat of jelly and repeat the process until you get what you want did not hurt the existing chrome wash with water and wala brought back a set of chrome wheels like this and was very surprised at the result

Brush it first, then try a small patch with Vinegar and let it soak. I recently cleaned up a badly rusted bumper jack with vinegar. Worked well and it is not real harsh. When I had the radiator out of the 52 I filled the block with a 50 50 mix of water and vinegar and let it sit for a week while the radiator was gone, flushed with cold water and cannot believe the stuff that came out of there.

Thanks, guys. You've given me some good things to try. I just remembered that I have a damaged piece of stainless. I think I'll see what the HCL does as an experiment. I like the Naval Jelly idea, because there is very little chance of it running around to the front side of the parts. I'll let you know how it goes!

Scott I have done the naval jelly lots over the years and it does not affect good chrome as it attacks the rust you may lightly brush with the steel wool as the 000 is not very abrasive and use it between each coat of jelly the jelly that i use is pink in color and I found mine at Ace Hardware

Since rust converter (like the rustoleum variety and others similar to it) spray dries clear (everywhere except rust which turns black) I'd shoot it on the backside to seal the metal, then coat that with the paint of your choice (I used silver).

Hi Guys,
I did an experiment on a spare piece of the front grill that I have. I put one end in a pan of muriatic (HCL) acid for 10 minutes. It totally removed the rust on the back side, but turned the chrome to a dull gray. HCL is definitely out!
Next, I tried the naval jelly, applied directly to the chrome. After 10 minutes, I could see where the jelly was applied, but it was still shiny--no dull gray. My conclusion is that careful use of naval jelly should be OK.
However, I opted to use the wire brush approach--a circular brush in my angle grinder. After removing all of the rust I could, I used the rust converter. Tomorrow, I'll prime and paint it.
I DID use HCl on some of the smaller metalic parts that I could remove (no chrome). It, of course, removed all of the rust.
Thanks to all of your for your advice.
Scott A.

Rather than HCl, consider using a treatment such as Rust Mort. It is a phosphoric based conversion treatment that will oxidize the rust and render it inert. Google for more info. I used this product for areas on my Jag. Followed with primer and top coat. 20 years layer, no problem-0
