Try cleaning out 8 165 gallon enclosed tanks of the sticky, slimy, reeking, liquifeid remains of 1800 pounds of dead fish sitting in 95* water for four days....FUN stuff!!!! Put a small amount of Vick's Vapo-Rub in each nostril and a little below your nose....kills all the odor of dead animals. It took 2 hours and 2 applications of Vick's to get the job done...didn't wretch once!
