Prevue Pet Products Tinkle Turf System for Dogs, Large

We live in an apartment with a balcony - this mat has been a life saver and hugely helpful in the potty training of our puppy. We got her at 8 weeks old and now she is just over 10 weeks old. We do take her outside the apartment to go potty throughout the day, but because of the frequency of which needs to urinate, we have this on our balcony and keep the door open and she just trots out there herself to use it now. We had to train her in the beginning to use it, but now she uses it on her own. It's also super helpful for middle of the night potty breaks. I imagine that in the future when her bladder is bigger, we won't need to rely on this, but for now it's so convenient! The only downside of this mat, which seems completely unavoidable, is the smell - and cleaning it isn't super convenient in an apartment. Our balcony gets a lot of sun and the heat + urine smell can be pretty unpleasant. We don't have a personal yard and a hose where we can spray it down, so we take the mat into our bathtub and wash it with dishsoap, vinegar, and hot water. We've washed it twice now but probably need to do it more. We also put pee pads underneath the grass, so that we can just throw those out and every now and then we'll spray the bottom tray with vinegar/water and wipe it off. Still giving it 5 stars because I don't think the smell is a product design flaw, just the reality of apartment living. I would also love if they sold replacement grass (don't need a new black tray) that we could buy but I don't see anything on Chewy.com.
