Sweep it and cover with a outdoor rug. There are some pretty ones and the prices are good. I put a green grass rug on mine this year and I like it.
there is a product for cleaning concrete, found it at a lumber yard. worked very nicely.
Wet & forget outdoor is a great no scrub product that works over time to clean. You can also use a good corn bristle broom and use it as a scrubber with an outdoor cleaner.
Thank you so much for all your suggestions!
