Bio-Clean Drain Opener 16 oz - Bio Enzymatic

This is a great product but what is really wonderful is the customer service! My bottle was delivered half empty and I posted a comment and a week later I received a replacement. Thank you

We tried lots of home remedies for drain flies. Nothing worked. We didn't want to use harsh chemicals, so we tried this product. It was easy to use. One treatement and the flies were gone. Worth every penny.

Followed directions. Let sit in drain 48 hrs. Opened up my drain.

A little expensive, but if it works well, it will be worth it. Just 2 weeks since first use and plumber advised using it every 2 weeks for 2 months. So far so good.

No smell and nothing to damage pipes. Helped but ended up calling plumber.

I didn't have a complete blockage so I don't know if this was very effective or not. My drain is still slow so I don't know if there was any real improvement.

Used this on my tub/shower drain. Left it for 24 hours as indicated. Also used baking soda/hydrogen peroxide/hot water. The combination of the two methods worked wonders on a slow drain. I heard a “glug-glug” sound and the drain cleared! Not only does it drain perfectly now, but this enzyme cleaner also cleaned the drain too! The company also sent two free bonus samples of other products to try. Highly recommend!

This product worked to clear our bathtub drain. The plumber suggested it when we had a clogged sink. We ended up using 2 bottles, but it worked great. We were pleased!
