for some reason the concrete portion of my yard, has green stains, It just appeared one day. Does anyone have any home remedies to get rid of these stains ? or products they recommend.
Try some soapy bleach water in a bucket and "mop" it on with a stiff bristle broom. We used to do this every year on our deck. If you don't want to use bleach, you could try oxy clean though I haven't tried that.
thanks ill give it a try !
