Glad I could help. I use chlorox in a garden sprayer mixed with water. I wet the concrete with water from the hose, spray the driveway in sections using the chlorox and let it sit for about 15 minutes. I rinse it off with the hose and it looks brand new.
A Heavy-Duty Floor Cleaner
Here's a recipe for a solution that will remove extra-tough dirt and grime from asphalt, glazed or unglazed ceramic tile, concrete, flagstone, and slate floors:
Mix 1⁄4 cup low-sudsing, all-purpose cleaner; 1 cup ammonia; and 1⁄2 gallon cool or cold water. Caution: Wear rubber gloves, and work in a well-ventilated area when using this powerful solution.
Apply the solution to the floor with a sponge mop, using pressure for heavily soiled areas; rinse with cool, clear water for spotless results.
Dry with a soft cloth.
If you're using bleach, be careful not to get rinse water on your grass. It could kill it.
I use a power washer on mine, but I bet that Greased Lightning would do a good job.
On my driveway I have a nice border on the edges thanks to my lawn service I don't spray the water hard, just use it with an open hose and wash the water down the driveway. I'm also using a diluted mix so I've never had any problems with my lawn. When it's done it looks like brand new concrete though.
Thompson's also makes a good concrete sealer. After it's clean and dry, you can put that down which will help protect it for a year or so.
