I have spilled coffee on my concrete patio floor several times now. These stains are old so they are strongly set in. I hate seeing them and can’t wait for some advise!

Try some bleach and some dishwashing detergent. Scrub a bit let it sit and rinse it off. If it lessens any try it again.
Good Luck!
Edit: oooooor I don’t know how likely this is but if you have a neighbor with a pressure washer that will get it out in an instant! But you’ll have to do your whole patio or it will be too clean in that one spot! lol
You maybe able to rent one too if no neighbors have it.

this sounds gross but it is a miracle product.
“Urine Gone” you will find it at target and Walmart… it gets our blood, pet stains, ANYTHING… i used it to brighten up my couch (white) and i ended up having to work on the entire couch becuase it was whiter originally than i knew!!!!!
i use it to get every stain out and it works amazingly!

go to a hardware store or somwhere that sells concrete and all the tools for it and ask them for cleaning acid . . . it will make your concrete look brand new

muratic acid { be careful } jojo
January 12th, 2010 at 10:29 pm
hydrochloric acid…toilet bowl cleaner…it will cause the calcium in the concrete to bubble up…after that it will all be nice and white…wait until the bubbling stops, then hose off.

I’d just use a pressure washer
It cleans off anything from anything.

Oven Cleaner”Easy Off” use the “Fume Free” version

Go to a pool supply store and get some muratic acid.
Careful not to let it sit too long as I will take the top layer of cream off of the concrete.
January 13th, 2010 at 12:25 am
Try oxyclean. That stuff works miracles.
January 13th, 2010 at 1:24 am
well if none of the things worked try to put panit on it or just call the cleaner’s they will know what to do

ONe of the best all purpose stain removers that I have used is making a paste with baking soda and water, and scrub with that. It took permanent marker out of my hard wood floors and I barely had to scrub. Good luck!

the soda drink…Coke…belive it or not I have tried it and it shows a difference

If you find a way, and if you’re bored, please email me and tell me how you did it. I can’t see how results would be dramatic; but you could probably help the stains with some of this advice you’re getting through all these people.
Oh yea…. I personally would stay away from muriatic acid… although it is sometimes used for cleaning up excess cement; it reacts with and EATS cement upon contact. Yes, masons use this (this is in my area of work) to clean off excess cement that is on the face of bricks that otherwise makes for a sloppy looking job… but masons try and avoid using it, as it erodes the outermost SMOOTH face of the finished cement instantaneously and leaves it more vulnerable to water infiltration , plus erodes your cement instantaneously, leaving it more suceptible to taking on stains in the future. I think it’s a safe bet that the stain has seeped into the concrete, and is below more than the surface, so this wouldn’t remedy the situation.
One idea… if you find something that would break up old coffee stains out of fabric, the same will probably work in the concrete. Allow a diluted solution of that cleaner to soak on the stains; let it soak in deeply. Be sure to first check an area in the corner to make sure the cleaner itself does not end up staining the floor (which test could take days.) You are going to have to “lift” the stain out of the concrete, which is going to require some sort of “lifting” suction action. How about a towel spread over the stains and pour salt all over it? This will “suck” the water and cleanser out of the concrete, and hopefully at least some of the stain along with it. I’m not sure the towel would be enough to stop the salt from seeping through the other way, and leaving possible salt stains as a result.
That’s a touchy situaton you’ve got there. I’m not sure you’re going to fix it…. without painting the surface or something along those lines.
Hope I’m not just rambling….
for what it’s worth.

What mason’s use for this , to clean mortar off of brick-surfaces, excess-concrete, etc.etc., is called “Muratic-Acid”. It comes in 1-gallon containers at msot hardware stores. You will want to “Dilute” it before using it though with water. just using it right out of the jug will eat a hole in the concrete. Mix it with water, maybe start with half/and/half, half water, half acid, and if that is not strong enough, add just a small-amount at a time until you see it is working. also, remember, after using this, you will want to wash the same area with soap and water to break-down the acid completely, or it will leave a stain as well. Do-NOT smell this stuff when pouring it to mix with water, it can cause nose-eye burning thats really irritating. Just keep your eyes protected from splashing, (Saftey-Glasses), and your head at a safe distance not to breath the fumes. Once diluted, it is not bad at all. But right out of the jug, you can actually see the fumes. A 5-gallon-bucket is a good thing to prepare your mixture in. It will work for sure, I have used it mant times before. Just be cautious with the stuff because it’s really potent. wear rubber-gloves when applying it also, it can make your hands real dry, and chafed. So, just be carefull with this stuff, read the cautions on the container, and this will work, I can guarantee this. Hope this helped.

Try TSP (trisodium phosphate (which ironically can be bought phosphate free)); it’s very cheap, too.
January 13th, 2010 at 5:15 am
Put some bleach on it, let it soak for about 10 minutes?
Then take a pressure washer and wash it off. If you don’t have one take something like a brush and scrub really hard.
It should come off.

Try naval jelly. Its a wierd purple liquid that works well on concrete.
January 13th, 2010 at 6:43 am
try bleach or vinager
January 13th, 2010 at 7:10 am
your best bet would be to use a pressure washer.
January 13th, 2010 at 7:38 am
I just saw this on TV… wet the stain first then put dishwasher soap on the stain… and work in with a brush and let sit for 15 minutes… works like magic
January 13th, 2010 at 8:06 am
I would try gasoline or kerosene. It’s used to remove paint. A pressure washer with some Greased lightening would do the trick. I used Greased Lightening inside of stained coffee pots when I cleaned offices and it makes them like new!

i read long ago that you should use shout on any concrete oil etc…so i did when the repair man left a trail a mile wide on my white concrete…i used the shout stick and a tooth brush worked it on and let it sit..i rinsed it off and did it again in any spot that needed it..i think with the new shout in the blue bottle it would be even easier…also what about some white wall bleach..i have super white spots of that on my driveway..so that too may work

Dish soap and a stiff brissled srub-brush. It takes time and energy, but it works. Muritic Acid should only be used by a professional. I have cleaned many fireplaces with good old dishsoap. Concrete is pourous and absorbes whatever is spilled. Coffee is masonry’s enemy. Muriatic acid will do the trick, but remember, it’s very dangerous. Call a local Mason Contractor.
