A smooth, uniformly colored concrete patio, driveway or walkway is an attractive accent for any home. Concrete provides a durable, sturdy surface, but concrete is porous which makes it susceptible to stains. It's easy to accidentally drop a pen onto concrete only to find that the ink has left a mark. Luckily, you can usually remove ink stains from concrete if you approach the problem with the right technique.
Spray down the stained area with water. Sprinkle a powdered oxygenated cleaner onto the stain and let it sit for one hour.

Fill a bucket with soapy water. Dip a scrubbing brush with stiff nylon bristles into the bucket and use it to scrub off the stain. Rinse the area thoroughly.
Cover the stain with bleach if any trace of ink remains. Let the bleach sit for about 30 minutes. Scrub again with soapy water and rinse.
