It was the bane of my existence the 1st 5 years in business. Everyone saying there's was the "most powerful", which usually meant higher Ph. or solvent level.
it got a lot better after I took some IICRC classes and learned the chemistry of carpet cleaning. Success comes from using the proper Chemical for the task.
But for 200pigs….it needs to be flooded with very potent products that we wouldn’t use in a closed up house.
I’ve tried all the presprays, enzymes, and acids we use.
The over the counter products work best on situations like this. Some day, some other dude is gonna run into a situation like this and he will thank me for posting so much about this. FFA isn’t going anywhere anytime soon
