I currently use a product for rust removal on concrete, and it works very well. But,..the results aren't immediate,..you have to wait for the concrete to dry and then it looks great. I've done several concrete driveways that have rust damage from what I assume is from snow plows scraping the surface and leaving metal filings embedded into the surface.
Actually I use a two step process, I use the main product bought locally. Then I follow up with oxalic over the entire surface to bring it all together. Works well but I hate the idea of no instant results.
Does F9 give results without the wait of drying? I actually bought some and am gonna find out for myself, just wanted to get some input beforehand.
* Also, if this isn't consistent with snow plow rust, please tell me what it is,..because that is just a guess on my part. Plus,..these are actually insurance jobs in this development from the same snow plow guy. I wish I had a better answer for him. But, cleaning is better than the alternative,..and he'll keep the customers.
** The whole driveway is this way down to the road, and the curbing has scrapes in it horizontally,..just like the edge of a plow would do in my opinion. Also,..the first 4-5 ft. out from the garage is rust free,..probably doing this area with a shovel?
Thanks,
Jeff
