As you can see in the pictures, my front porch has a crack surrounded by rust running across it. I'm thinking the concrete cracked open and allowed moisture inside which caused the rebar to rust. Someone else had a problem similar to this on another thread.
I have two questions:
1. Is there a really thin epoxy that I can insert into the crack with a syringe?
2. Is there a way to remove any of the rust without damaging the concrete?


Other suggestions are welcome.



We moved here three years ago and it looks the same as it did then. Not ready to tear it out yet.


Thanks for your help!

Floor neutralizer should remove it but you can try vinegar or citric acid too.

Thank you NealTW

I will try the vinegar next and then citric acid. I tried both CLR and Iron Out and could not see any difference.

After a car leaked rusty water on driveway, I was told about the neutralizer. It worked so well it took the stain that was put on the concrete when they stamped it. Who knew the stains for coloured concrete are made from iron.

Here is an idea on how to remove the rust without damaging the concrete. First, spray white vinegar on the rusted surface. Let it sit for several minutes and then start scrubbing with some wire brush. You can rinse away the rust with cold water after.
