My wife says "enough already". I have to get rid of the stain and she
doesn't care if I figure out where it came from. ;-)
I'm going to try some bleach and some standard cleaners on some small
areas. Does anyone have any suggestions for what type of cleaner might
be most effective?
Try some lemon juice from the bottle on a very small area. Let it sit for a
minute and rinse well.
While we are at it, how deep is the paver base in this area? Everyone
thinks the stain is from above. What if it is coming from a chemical
reaction from below? Some trees secrete nasty stuff from the roots though I
am at a complete loss as to what it might be in your case. I recall getting
orange hands while pulling out the roots of some tree/bush.
I can't see it coming from below. The pavers are 3-4 inches thick.
Under that is about 2-3 inches of gravel. Under that is 2-3 inches of
new dirt leveled and compacted. And, the stain appeared in just a few
hours and is in the exact shape of the tree shadow.
Anyway, thanks for the lemon juice suggestion.
Pavers are stored outdoors in all kinds of weather. They probably get
saturated and take time to dry out. The pavers that were put down in the
sun probably dried enough, but the ones in the shade are still damp. You
probably noticed the difference because when the pavers were freshly
laid, they were all equally damp.
Spray some water on the dry ones around the shaded area and see if they
all become the same color as the shaded ones.
Why don't you just call the contractor up and ask him to take a look. He
might know a helluva lot more than the people here. If not too many pavers
are involved, he might even be nice enough to replace them for you at a
reduced price or for free.
As others have said, try soap and water first.
If and when this doesn't work, you might want to find some Prosoco
SureKlean, it should be available at any brick layer's supply
house or a brick sales place should be able to tell you where to
I would certainly ask the supplier or contact Prosoco to discuss
compatibility. You will probably need to clean an area larger
than the stain to keep everything looking right.
The stain looks a bit like someone throwing a 5 gallon bucket of
some liquid from the grass side.
Keep the whole world singing . . . .
