Projects Citric acid mix on chrome. It works.

Before and after pics.

 

Yup! Do a neutralizing rinse, get it good and dry and party on!

 

How long did you leave them in the solution?

 

Look great!
what mixing ratio and citrus product?
parts submerged ? heated ? How long?

 

Geesh, maybe a week and a half? Was kinda a week mix, so just let it sit and swished the pail around every few days.

 

Yah, what dude and Dan said. Youth wants to know.

 

We posted about the same time.
I’m thinking about a week and a half.
Working a night shift, I sorta lose time of things.

 

Just sitting in a cold water container. Outside, was a bit weaker than suggested. I think about 1/2 cup per gallon of water, maybe a bit more CA as I dumped the last of the bag in.

 

Yeah 1 cup to gallon is usually strong enough to do that in a day or two. Take it out every 12 or so hours and wipe the sluff off and check on it. Works great and is safe to dump

 

This is from a 24 hours soak,maybe 15-20% C-acid.

 

Thanks guys. I use it often enough for basic Ferrous parts, but wondered about chrome items. Didn't think there would be an issue, now I know. The proof is right here.

 

I too had wondered. I’ve some chrome parts I need to make containers for (bumpers. Etc.

 

I find it helpful to take out the item and brush off what you can (every few days) and put it back in

 

What product did you use?

 

Amazon, let me look and I’ll edit my reply

Pretty sure it was Millard food grade.

 

I've drug home some pretty nasty rusty parts, only to hope they could be saved. Citric acid is my first go-to for soaking. Soak for 24 hrs, rinse, dry, wire brush... repeat 3 times. I have all types of wire brush, down to dremel size. Really stubborn rust, I will use muriatic, then neutralize with baking soda/water rinse. Evaporust works, just cost more than the citric acid crystals. I realize these are not chrome parts, but the citric solution does work on rust, chrome or not.
