Help: Removing rust spots from grey river rocks.
 

I have a large quantity of grey Mexican river rocks that have aquired
rust spots of varying degree on their surfaces. Is there a way to
remove these spots without destroying the surface of the rocks?

Thanks to all.

Just for the info of others CLR did not remove the rust from the
rocks. Talking to various landscape suppliers in their experience
nothing will take out rust from rocks. Of course that could be because
they want me to buy new rocks.

Again thanks to all.

Purchase a product that removes rust. Naval Jelly, CLR, Zud, The
Works, all remove rust. Most of these contain oxalic acid. But, I
would not uses any of these if you intend to use the rocks in a fish
pond.

Then the only alternative is to abrade the surface carefully to retain
the contours. --Don't- use a steel brush. There are various flexible
grinding discs out there. Try one on a rock and see what happens.
The surface should eventually weather to grey. You may have to remove
a good bit of rock if the stone is porous.

Wear good eye protection if you try this.
