    You can pressure wash or add an attachment to make you garden hose a high pressure hose. If you need to add something like Krud Kutter or a homemade scrub of baking soda with vinegar and dish soap then hose off after letting sit for a few minutes.

    I use a cleaner degreaser from the auto store with a power washer. If you have mildew make sure you use bleach. If using a hose, use cleaner with a strong broom to scrub and rinse off.

    You can use one or more of these solutions for cleaning concrete

    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.

    Mix 1/2 cup baking soda to one gallon of water for a gentle cleaning solution. Add 1/8 cup of liquid dish detergent. Spray on patio surface, let sit for 30 minutes, then scrub and rinse. For heavily stained or mildewed patios, you may need a pressure washer.

    We just use our pressure washer every year. That alone gets of drops of dried paint, chicken poo and the green slimy crude that builds up every year. If there is a oily stain a little dawn before hitting the spot with the pressure washer usually does the trick.

    Hi Mary: This site is for a basement, but should work for you:

    Good luck

  • Just use a mixture of half a cup baking soda to one gallon of water for a gentle cleaning solution. With that, you need to add 1/8 cup of liquid dish detergent. Then simply spray the mixture to the surface of the concrete porch. Just allow it to sit for about 30 minutes.

  • I’d use a power washer. If you don’t own one you can rent them from your local home improvement store.

    I would buy a deck scrub brush that's on a long handle and after hosing down the porch,

    Pour a 2 gallon bucket of 1.5 gallons of warm water, a cup of oxygenated bleach, 1/4 cup Dawn,

    onto the concrete.

    You'll want to wear rubber boots.

    Scrub the concrete with the brush and let it sit 15 minutes and scrub the stubborn spots again.

    Put a spray nozzle on your hose and blast it while rinsing off the porch.
