InVade Bio Zap Odor Eliminator1 Gallon

I have used Bio Zap at home and work;Sadly, a skunk died under the shrubbery next to my house. Double bad smell!! I poured a liberal amount of Bio Zap all over it 2 days in a row, and by the next week it was gone. I also sprayed a large area of our side yard where the neighborhood critters think their bathroom is, and where organic detritus also tends to collect. I can never open the windows on that end of the house because of the musty/urine combo odor. I only had enough Bio Zap left for one application; it almost completely got rid of the smell but I need more to keep up effectiveness after rainy weather/more cats visiting.At our apartment complex I've been using BioZap for some months, to clean mostly cement - grease at BBQs, bird poo, sap, various other spills/substances, and also our water-less urinal. The bird poo clears up surprisingly quick; I’m not sure if it is slower at eating grease or if there are just more messy people at the BBQ’s . Most other stains/substances clear up within days. Those old gum spots don’t, but this week I tried scraping them first; we’ll see if it can eat it now.I want to order a large amount to spray in our dumpsters to clean built up crud/eliminate odor; but if I am going to spend this much I want the most effective of your products for the job(s).
