Hi everyone, I hope I remember all of the questions I was aksed.
How to clean
You simply pick up the tray from the base. The turf will remain on top of the tray. I washed my tray and turf/grass in my laundry tub. First, I removed the grass and threw away the pee pad. I then washed the tray off and put it to the side. I then rinsed out the grass with regular water. I then plugged the drain and let the grass soak with cleaning stuff and water for about 10 mintues. I drained the water and shook the gass out. Last, I used and old towel and dried it off. I do this every 3 days.
If you smell an odor more, then you can always switch out the pad without cleaning the grass. I have three girls using it and every 3 days has worked for me. If only one baby is using it, then you might not have to clean as often as this.
Fence question
I made the fence myself. I bought it from Lowes. The potty place only sells one piece for the longest side. This wouldn't work for me, so I had to create my own fence. I found my fence in the yard and garden section at Lowes. It was very cheap. I think a total of $10.
