Review on Bio-Clean Ultimate Drain Cleaning Kit: All-Natural & 100% Guaranteed to Clean Drains, Septic Tanks, and Grease Traps! No Caustic Chemicals, Removes Fats, Oil, and Grease. Complete System Cleansing! by Jhon Clark

What a Great System! I bought this because I had slow (almost clogged) drains in my bathroom. Used the included plastic tool and pulled some nasty hairballs out of my tub and sink drains. I could see that there was still some ugly black goo that I believe had seeped deep into my pipes. I have treated my drains with Bio-Clean according to the directions for 5 days in a row and am happy to report that after two weeks my drains are working like new! Thanks to the plastic cup, application is very easy and I really like the little reminder. Thank you Bio-Clean for saving me hundreds of dollars!
