Hi there,

I have been out with my power washer trying to clean my patio without
too much success.

It is covered in green algae which the power washer is not removing
completely

Any suggestions please. Must be safe for my dogs.

I use a couple of cups of Clorox and a cup of TSP in a gallon of water.
Scrub that in with a brush or broom. Let sit a few minutes and then rinse.
That shouldn't take care of it. I won't hurt the dogs as long as they
aren't drinking it out of the bucket.

TSP = Trisodium Phosphate. You can find it in the paint department of the
hardware store. You could also just use some Spick N Span, Soilax, or
powdered laundry detergent. I use the bleach/TSP solution on my deck and
siding to remove the green algae. I have dogs. The solution doesn't seem
to hurt the plant or the dogs. Of course, I would recommend rinsing with
lots of water.
