Not sure where to post this.. so I figured I'd post it in General!

We live in a townhouse.. and our backyard is a patio.. surrounded by rocks. Zeke and Eli both go to the bathroom on the rocks, so urine smells/stains isnt a problem. But lil miss Bunny has to ONLY go on the patio (its aggregate). So.. after a day or so, its stinks and its dirty.. so I was wondering..

Whats environmentally safe and yet disinfecting enough to clean my patio?

I was trying to Google-search but all I could pull up was UK-based products. I do poop-scoop several times a week, rocks and patio, but the smell gets awful... Unless it rains, or I hose it down several times a week. But even then, its not really.. Clean.

So for those of you with dog runs or backyards similar to mine... what do you use?

Oh and what do you do with the poop? We've been using a kitty litter plastic container w/ lid but I was wondering if there was something better... Any suggestions will be appreciated.
