HELIX LABORATORIES, INC. BioFresh - Enzyme Drain Cleaner & Smell Remover for Garbage Disposals, Fruit Flies, Shower, Washing Machines & Slow Drains - Sink Drain Clog Remover & Odor Eliminator - (32oz)

My guest bathroom started smelling like sewage. I couldn't find any reason for that...the commode was sparkling clean, the sink as well, and the shower hadn't been used in over two years and was also very clean. Had a plumber come in, he said that the u-shaped trap under the shower had dried out. That allowed unobstructed passage to the sewer line. Hence the smell. I needed to run the shower for ten minutes or so to refill that trap area with water. I did that. The smell diminished, but was still there. Got a bottle of this Bio cleaner and poured about a cup around the shower drain, allowing it to go in along the sides. I waited a few hours, went back and ran the shower again. Smell is gone. Relief! Will continue to use occasionally, and will run the shower at least once a day for a few minutes to reload the trap area. UPDATE: Several days later..no smell. It totally works!

The amount you get is good for the price. I used it for a drain system (on septic) that had a foul smell. The odor was not something from backup lines but within the main drain from the kitchen. The shipment was within 2 days and I’m not on prime and I requested normal delivery. I gave 4 stars for the liquid texture. This did 95% of the job however I believe if it were more sticky And less runny it would have stuck better and cleaned more on the top end than immediately running further down the drain. My issue seems resolved for the most part and I still have plenty of product to use in the future.

Worked magic on my toilet and shower No more musty smells

Helped my garbage disposal improve drainage but did not fix the problem. Have tried two other drainer cleaners but still have the problem. I may have to call a plumber. The disposal comes on but the blades don't turn now; I tried to find a reset button but so far have not discovered it. This cleaner is simple to use, just pour it in-close the sink and let it set for several hours. I think if it were used regularly, it would keep your drain open.

After facing the likelihood of a repair bill, some research lead me to try this enzyme product. After attempting (while making pickles) to grind the green peels of watermelon rinds my dispisal jammed to the point that I was planning to call a repairman. The enzymes work like a miracle and cleared the clog quickly and easily. You just pour a couple ounces in the drain and leave it overnight and voilà.! The drain flows freely in the morning. I am so pleased with this product. I’ve decided to use it once a month as a prevention and a cleaning medium in all my drains.
