We have a large concrete patio under a big maple and it gets really dirty. There are perennial borders and lawn around it, so I need to use something safe. I've heard baking soda is good. But - how do you rinse without squirting the baking soda all to the edges and then having it just sit there?
I thought about dispensing with the whole idea of rinsing and just getting something absorbent, like little sponge pieces, throwing them down, wetting them, then letting them bring dirt up and vacuuming them up. Sponges are expensive, but something with a sponge action, like those little white balls you see in potting soil (forgot what it's called). Would that work?
Am I on to something or would it just be a huge mess?
Here's a pic of my patio . . .
