The most common way to remove discoloration caused by water is to use a heated pressure washer, or acid rinse. Once the stains have been removed, it is important to seal the concrete to reduce future staining.
To change the color, we're covering the two most common solutions here: You can re-stain the floors (by applying a new penetrating sealant) or paint them (by applying an industrial coating).
Although concrete stain is permanent and won't flake off like paint, it penetrates only the top layer of the concrete surface and will eventually wear away as the surface is worn by traffic or weather exposure.
White vinegar and a little scrubbing with a brush is a very effective, eco-friendly way to remove rust stains from concrete—even those that are decades old. Pour the white vinegar directly onto the stain, allow the liquid to penetrate the area for 20 minutes, and scrub with a stiff-bristled brush.
You can use a water hose or power washer. If it is waxed then follow the instructions for Interior. If it is not waxed, then since there is no wax to protect the outdoor concrete sealant, it will wear and need to re applied occasionally.
Will Vinegar Damage Concrete? Cleaning concrete with vinegar will not damage it! However, saturating concrete for an extended period will damage the cement that binds concrete together. Over time, vinegar erodes the concrete itself, so be careful.

To sum it up, most interior projects and all exterior projects choosing between concrete stain or paint are likely better served by a stain solution. Furthermore, horizontal surfaces are best benefited from an acid stain, while vertical surfaces require a professional mineral stain solution.
Sunlight can damage dyed concrete floors, causing vibrant colors to fade. Check if windows in the room are made with glass containing UV-protection, which can keep floor color from fading.
If you need to get rid of rust from concrete, your best bet is to use some WD-40 Multi-Use Product, and some elbow grease. WD-40 is specially formulated to be a penetrant, so when you spray it on a rusted surface, it gets to work right away by getting under the rust.
You can fill a spray bottle with a 50/50 mixture of vinegar and water, adding a few drops of liquid dish soap. Spray this solution directly onto the concrete, letting it rest for around half an hour. If you leave it on too long, the vinegar can eat through concrete parts.
