How can I get red wine stains out of concrete patio?

Apply a 1:1 ratio of water to white vinegar and scrub with a sponge soaked with water and dish soap.

I would think spaying it with bleach then power washing would work.

Add a few drops of tea tree oil and glycerin (can be purchased at a drugstore) to a few quarts of water in a bucket. Scrub the wine stain with the mixture and let it sit for 20-30 minutes. Don't let it dry too quickly–apply more if necessary. Scrub again and rinse.

One of these solutions should work.

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.

Try lemon juice!

To remove red wine stains from a concrete patio, you can try the following steps:

1. Blot up as much red wine as possible using a clean, dry cloth.
2. Mix a solution of one part water with one part white vinegar.
3. Using a clean cloth or sponge, apply the vinegar solution to the red wine stain and scrub gently.
4. Rinse the area with clean water and blot dry with a clean cloth.
5. If the stain persists, you can try using a commercial concrete cleaner or a paste made from baking soda and water. Apply the cleaner or paste to the stain and scrub gently with a scrub brush or a stiff-bristled brush. Rinse the area with clean water and blot dry.
6. If the stain still will not come out, you may need to use a stronger cleaner, such as a product specifically designed to remove red wine stains. Follow the instructions on the product label carefully and test it on a small, inconspicuous area before using it on the stain.

Keep in mind that it may take several attempts to completely remove the red wine stain from the concrete patio. Be patient and persistent, and the stain should eventually come out.

To get the red wine spots out of your concrete or brick surfaces, scrub your wine stain with soapy, warm water and a stiff-bristle brush. Wash the soap away with cool, clean water. If the stain remains, dab it with hydrogen peroxide or diluted bleach and let it sit for 5 minutes before rinsing with your garden hose.
