    Hello. We powerwash our 200 foot driveway with commercial cleaners designated for this use.

    Alternatively—Heres a link with helpful ideas if you don't have a pressure washer. Hope it helps.

    Pressure washing would be the best method. If you can’t do that, get a high pressure wand to add to your garden hose.

    I would wash off and then if there is discoloration use krud kutter or diy a solution 1/2 cup baking soda 1 gallon water 1/8 cup dish detergent. Sit 30 minutes then wash off, scrubbing if needed.

    I agree, pressure washing takes care of a lot if not all of that. It should even take off any moss on there

    Yes, it's time for a good pressure wash! You can rent one from a local rental place. Plan your work so you don't have to keep it too long. I'd first spray the entire area, spray on a good cleaner, use a push broom to work the cleaner around and then pressure wash all of it away. You may be surprised at how nice the concrete looks afterwards.

    A pressure washer would be the best way. Try some of these

    WD-40. Did a leaky oil pan leave a big ugly spot in the middle of your concrete driveway? To get rid of an unsightly oil spot, just spray it with a generous amount of WD-40 and then hose it down with water.

    Soda (Coca Cola). Here’s how to remove oil stains from concrete drive-ways and garage floors: Gather up a small bag of cat litter, a few cans of cola, a stiff bristle broom, bucket, laundry detergent, bleach, eye protection, and rubber gloves. Cover the stain with a thin layer of cat litter and brush it in. Sweep up the litter and pour cola to cover the area. Work the cola in with a bristle broom, and leave the cola for about twenty minutes. Mix 1/4 cup laundry detergent with 1/4 cup bleach in 1 gallon (3.7 liters) warm water and use it to mop up the mess.

    Oven Cleaner. Get those unsightly grease, oil, and transmission fluid stains off your concrete driveway or garage floor. Spray them with Easy Off No Fume Oven Cleaner in the BLUE can. Let it settle for 5-10 minutes, then scrub with a stiff brush and rinse it off with your garden hose at its highest pressure. Severe stains may require a second application.

    Kool-Aid. Nasty rust stains on your concrete? Mix unsweetened lemonade Kool-Aid with hot water. Scrub and the rust stain should come right out.

    Baking Soda. Salt and commercial ice-melt formulations can stain — or actually eat away — the concrete around your house. For an effective, but completely innocuous, way to melt the ice on your steps and walkways during those cold winter months, try sprinkling them with generous amounts of baking soda. Add some sand for improved traction.

    Ammonia. Tired of those annoying discolorations on your concrete work? To get rid of them, scrub with 1 cup ammonia diluted in 1 gallon (3.7 liters) water. Hose it down well when you’re done.

    Every year we pressure wash our cement sidewalk and porch. Amazing the amount of crude that builds up. After a good washing the sidewalk looks almost new.
