Hi there. I bought a bunch of big aluminum screws to help secure an aluminum pergola I'm building (https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1)
I'd like to remove the zinc plating to reduce galvanic corrosion (I'll probably anodize the screws). I Googled it and found a couple tutorials around using citric acid and another using another type of acid. However, when I went to the hardware store, they had nothing of the sort.
Any suggestions for the best way to go about this (or where to get a strong enough acid) ? Thanks!
Thanks for the input, everyone.
Any idea what people use, then? I know pergolas (and other structures) made from aluminum are quite common. Surely they have some mechanism for attaching the aluminum to the ground, wall, or in my case parapet wall.
I don't mind just using these screws, assuming they're zinc-plated steel. I just was worried about galvanic corrosion over time.
Depends on where you live if you need to worry about galvanic
corrosion.
I live in the high desert of central California.
Bull****. I have shown repeatedly that your dump is at about 1025'.
There's a topo map that shows the 1025' contour running literally right
through your dump.

The street running right below the words "South Taft" (synonymous with
"Giant meth lab") is Wood Street. The red and white striped line
running between the words is Olive Av. You live on the east side of
Olive, two shacks above Wood. The dark brown line running through the
letters 'ft' in 'Taft' is the 1000' elevation line. The next dark brown
line to the southwest of that line, running just above "Conley School"
and through the red number "24", is the 1100' line. The intermediate
lines mark 25 feet of elevation gain.
As we can plainly see, the 1025' line runs directly through your shack.
Your claim to live at 1953' is bull****. But everyone already knew that.
The high desert starts at 2000' elevation. Your elevation is a bit over
half that. You do not live in the high desert of central California -
there isn't any such high desert.
