Those that use a hose end sprayer for sanitation and dissenfecting, what setting do you use?

http://www.dog-training.com/wysiwash.html I used this after i got Parvo, and it worked pretty well. You do get pool smell but it goes away in hours.

How does this work on typical urine odor in areas that are heavily soiled (meaning outdoor areas)?

SweetPDZ works great for urine smell.

it works for a while, but need more than just Sweet PDZ for heavily soiled areas.

True enough!
