Through my reading on urine decontamination, I consistently found that a urine pretreat flood & extract with water claw should be performed first to remove as much urine as possible. But afterwards, should I use OSR dwell 30 mins then extract, or should I use a product like matrix bottomline (enzymes). If enzymes, do you flood and waterclaw as well. I've never used enzymes before. Thanks ahead of time guys!!
