Removing rust stains from concrete?

Answer 1

Rust Removal from Concrete
You should be able to remove the rust stains from your concrete driveway by using any of the commercial rust stain removers out there. Some are Zud or Whink, and they are available at most department stores. You can also try scrubbing the area with TSP.:)

Answer 2

Just a thought, but it might be time to have it re-sealed and have a color added which will cover the rust stains? Most concrete is like a whiteboard or a light colored carpet; instead of enjoying it and its functionality, all you tend to see is what stains and dirt are on it. If it were me, I would get 2 estimates, 1 to have it cleaned and 1 to have in resealed and textured. Keep in mind a typically acid wash may get rid of the rust stains but it can also mess up the surface especially if it is not neutralized properly.

You can use CLR or get commerical bleach from lowes or home depot it is stronger then reqular bleach and will clean rust,dirt,or most any other stains on your concrete.

Answer 6

you should just put one of those two part epoxy finishes on, then you won't have to worry about anything staining it. they are heat, chemical, oil, gas, and grease resistant. if there is some pitting because of salt, or just old age you can get some concrete resurfacer made by quikrete. They are all easy to use and look real good. you just roll em on like you were painting. and the best part is that you can get them all at lowes or home depot. check it out:
