Zep Concentrated Industrial Purple Degreaser - 5 Gallon

I had a tractor fuel tank that got an algae contamination in it. About 4” of tar like sludge on the bottom of the tank. Nothing in my shop would remove it. Your ZEP purple cleaner did an excellent job. Thanks for the great products

BEEN USING FOR YEARS, IT CUTS THE GREASE

I like everything about it & will continue purchasing from Zep for my business
