I live on the 3rd floor (top) of an apartment complex, and one of my dogs has taken a appetite to peeing on the patio. I don't mind this, as its this or the inside of my house.. But some suggestions for cleaning would be much appreciated. The entire court is screened surrounded by, and also has vertical railing, so it'd be tricky to simply pour hot water near cleaner in it because the wet has no where on earth to go. The cement is serrated, so its fundamentally uneven and really rough, so it tears up sponges and paper towels, and even hefty cotton towels. There's also some staining from the urine, which sooner, I would love to remove. When it comes to cleaning stains inside, I have adjectives the solutions, but I'm at a loss in this situation. Thanks within advance.
I don't know what the smell is?
Answers:    I can suggest this . With a solution of ammonia and lemon liquid , this will rid the smell and the stains . Use a long handled scrub brush , Then a good behind the times fashioned mop with cold marine to lift it sour. Then with boiling hot marine and a mop . I think this would be the best approach
How can i draw from rid of mold...
A bleach and HOT water mix and a scrub brush. Being on cement you can basically let it dry and it won't hurt the surface. It may also obtain rid of the smell enough that the animal can't smell it anymore and will stop going on it, since that's probably what's going on within the first place.
