Cleaning Steel Prior to Painting?
 

When I put out the flag today I noticed that the steel wall bracket is
rusting, in spite of this being Arizona, where rust is forbidden ;-)

Do I remember correctly that cleaning steel in a mild acid solution is
the best treatment to remove the rust, then prime and paint?

You want phosphoric acid, IIRC. It's the stuff in Naval Jelly, at any
rate. It cleans the rust and leaves a mild, paintable, anti-corrosion
film behind.

I'd use a flap wheel or sanding disk to remove 90% of the crap. Maybe
a slosh over with phosphoric acid or one of the off-the-shelf
versions, then a coat of "Hammerite" works wonders. Limited colors,
but it's pretty tough.

If it has not reached the flaking point Rustoluem spray paint will do
just fine. Follow the instructions on the can. It will take at least
overnight to dry. If it has reached the flaking point mechanical
removal of the rust is advised!

I second the navel jelly. Then Murtic acid for heavy jobs ;)

BTW, use rustolium and their primer. If not I really like the Painters Touch
paint, really good UV protection.

Good man. We went to a parade today, out in the boonies. Scouts,
farmers, tractors, horses and so on. Then the Weber was fired up.
Country living is good. But after a parade with lots of horses it does
smell a bit ....

I'd go with John's advice. Brush off any coarse stuff with a wire brush,
then a fresh coat of your favorite color Rustoleum. Ace has some good
stuff as well. Initially I thought that there is no free lunch when it
comes to rust but my wife convinced me. She regularly spray-paints
rusted lawn chairs and afterwards the paint lasts years. And this is
Cahleefohniah where is does rain and freeze and all that.

By a vinyl holder. Wife picked up 2 for less than $2 ea. Otherwise remove
the rust mechanically, finish up wiht some naval jelly, prime and paint.

Not worth the two bucks to me.
When mine doesnt have a flag in it it holds a support for hanging flower
