Tarnish on Wet Cleaned Brass
« on: October 05, 2019, 06:57:12 PM »
Crushed walnut with a little nushine kept brass tarnish free for a long time. Since switching to wet leaning with citric acid, I'm noticing some tarnish developing. How do you folks go about preventing this?

Crushed walnut with a little nushine...

Did you possibly mean NuFinish car wax ?

To answer your question...
• First, cut your LemiShine back to less than 1 Tbs. Too much causes tarnish all by itself. More is not better.
• If you're using a detergent, like Dawn, then quit. Older cleaning formulas used dish washing detergents, but with the new wet waxes (listed next) you don't need it.
• Then there are 2 new wet wax solutions you can try: Turtle Wax Zip or Armor All Wash and Wax.

Hope this helps.   ;)

Thank you, Wobbly! A wash that contains a wax makes perfect sense! I'm using 2 tsp citric acid per qt water. Is this too much?

I use LemiShine so I can't answer, but LS has citric acid in it. As your formula stands right now, there should be zero brown or tarnish spots when the brass gets dry.

The wax is only there to exclude the oxygen and keep the oxides from forming. If the tarnish is already there, then the wax isn't going to do much for you. It's only going to preserve what you already have.

But I can say it won't hurt any to cut back on the citric acid and see if there's improvement. Everyone I talk to agrees... less is better.

Oops...transposed Lemishine and Nufinish!

I'm using citric acid for canning. Will try to cut back next time and use a wash that contains a wax.

Thanks again!

I use Vitamin C (ascorbic acid) with wash and wax.  2 or 3 generic tablets and a squirt of W&W with a load in the FART, no pins, comes out very clean and stays shiny.
