Rust Spots on Driveway Pavers
 

Has anyone experienced little rust spots appearing on some of their driveway pavers? If so, is there a solution?
Thanks

Fertilizer containing iron is the cause. The sun may bleach it a little.

You can remove the spots with a wire wheel on a electric drill. When you or anyone puts fertilizer down be sure it is all swept off the pavers, I learned the hard way. I just had my driveway sealed and had to remove the spots before they pressure washed it as they don't come off with a pressure washer.

Snowcap Rust Stain Remover easily removes the stains

Go to Ace Hardware, they have the solution.

I used everything suggested, Snowcap left white spots, Muriatic Acid left white spots, CLR did not work, vinegar, lemon, etc., nothing worked. Wire wheel on drill did the trick, it only takes a few seconds per spot, and no chemicals to mess with.

Could CLR help?

Didn’t work for post #6.

Weird, that post didn't show up when I answered the thread.

But then again, neither did my post...


Must have been a glitch in the Matrix...

Remove IRON spots with The Works Toliet bowl cleaner! I am not crazy, I've used it for years to remove iron stains. Only The Works has success because of the acid.

I have used Iron Out spray that worked fairly well.

Any suggestions for oil on the driveway?

Fix the leak first.

It DOES work !!!

Muriatic acid works. That is what the paver folks use when resealing pavers. Not sure how the previous poster tried to apply it, but I use a 50-50 mixture of muriatic and water. Pour a small amount on the stain, then rinse within 5-10 seconds. If you leave it there, it will discolor the paver, and may turn out to be more noticeable than the rust was! Repeat the process until the stain is gone. Sometimes this takes 4 or 5 cycles.

I had similar spots. Whitecap did not work. I figured out that what happened is a gut with an electric cart parked there after a rainfall. There must have been some acid on top of batteries and water got on top and the solution dripped off to damage concrete. So far no solution.

Oil is tough to remove. Products that are solvents, thin the oil and drives it deeper into the porous cement. You need to be stubborn-several applications. Dawn is a commonly sold dish detergent. You likely recall them bathing oil soaked birds in it. It works and is fairly mild. What you want to do is put it on and wipe off the liquid. Easy way, use kitty litter to soak up, draw out the liquid. You can also try ammonia a good oil cutter. Dish washing detergents also good grease cutters. Vinegar a mild acid. Muriatic acid a far stronger acid-it says protect your eyes for a reason. It is hydrocloric acid.

What does work?

And the wire brush takes a few seconds and leaves no residue or white marks. When you pour Muriatic acid on the stain it tends to run making an even larger mark on the porous pavers and to avoid acid stain you have to time the rinsing perfectly, too long you end up with white spots, not long enough the iron stain remains. Pavers are not the same as a concrete drive. The wire wheel is so simple, easy, and fast why not try it.
