Anyone have a home brew for getting rid of mold on concrete. Bleach is not doing a very good job.
Any suggetions?
Thanks,

This has worked for me as well. I let it sit overnight. You can tell which neighborhood cats have been there. They all have white feet.
GoodyGuy said:Bleach should do it. (do not dilute) Use either Regular Clorox or Ultra Clorox, full strength and leave it on 24 hrs.
Do not use Clorox II, because there is no chlorine in it. Clorox Ultra germicidal would be the strongest mold killer of all.
Wear a mask when using, to avoid breathing fumes.
Warning! do not add ammonia. It would cause a deadly chlorine gas that could kill or blind humans or pets.
You probably already know this, but someone else reading may not. Several are killed each year from accidental exposure to the combination.
If the mold is inside your home, get a professional or it will likely keep coming back

It was a stain not mold.

River Rat said:Ray, I have the same problem...I pressure wash, there's a nozzle thingie that goes into a bleach bottle and it sucks up bleach with water in a soak mode. After so many minutes, I start the blasting off. The brick patio does the same, when it rains I just add bleach to the bricks and let the rain water do it's thing.
