Zep DC16 Drain Care Build-Up Remover Powder 18 Ounces ZDC16

No amount of cleaners or bleach could get rid of the smell coming from our bathroom drain. Couple doses of this stuff and it’s good as new. Highly recommended!

As renters (who used to be homeowners), we noticed the drain of the kitchen in the house we are renting was emitting an unpleasant smell-- not like sewage, but something like old food-laden dish water. None of the solutions we tried worked, and meanwhile the kitchen was starting to smell pretty embarrassing, despite the sink draining normally. After doing some homework, we decided to try this enzyme cleaner. A scoop wasn't included in the bottle but we googled this, and found 1 scoop is approx 5 teaspoons, so we mixed 5 teaspoons into 2 cups of warm water to follow the instructions. After 3 nights of this treatment, the drain issue is solved. It seems to have improved the outcome of dishwasher use too, even though we didn't directly treat the dishwasher (the dishwasher drains into the same pipe as the kitchen drain). We'll do maintenance treatments as recommended. Just relieved this odor issue is resolved.

Worked great on drains. Bought a second to keep drains clear, and smell free

It did not kill drain flies like I expected,but maybe the drain is clean.

This product works great!! You have to follow the instructions, and use it for 3 nights straight, otherwise it may not work. I didn't fully understand about the drain cleaners till now. Some are meant to power through pipes and cut a hole through the gunk and have your drain open up and let the water flow through - like Liquid Plumber Gel, which are more like a strong acid to burn their way through. Enforcer DC16 is an enzyme based drain cleaner which actually eats away at the gunk in your drain, which takes a bit of time. Once it eats away all the gunk - your pipes are totally CLEAN and water flows great. That's why it takes 3 nights (of eating) especially when you haven't done this in a long time. I used this in my kitchen sink and bathtub drain for 3 nights. My kitchen drain was running just okay, so I used a plunger just like 3 times, and then suddenly the kitchen drain ran beautifully. However, then the bathtub drain completely closed and I was shocked at how much gunk came up - more than I ever saw. What apparently happened was that the enzymes ate the walls of the pipes (drain) and cleared off all of the gunk in the pipes but it overwhelmed the drain pipe, and now no water was going down. I put in a half of a bottle of the Liquid Plumber Gel, and it took almost one hour before the Gel (acid) burned through and the water then completely went down, and ever since the drain is the best it has been in a long time. Water flows down very well. The enzyme cleaner hasn't just made a hole in the gunk, but actually cleaned it out, which is what an enzyme cleaner does. Fantastic!!! Now, I just have to do the maintenance scoops every month or two months and the drains will be fine. It's really easy to use also. Just put the scoop in hot water in a 16 oz jar, and put in the drain at night - 3 nights in a row. I think it's always best to run some hot water in the drain - about 1 minute, prior to putting the enzyme down for the best results. I looked at other enzyme cleaners, and some are in liquid form. It's definitely more expensive (paying for convenience and water). This is actually very convenient with the scoop inside. It's cheaper, very effective, and takes up less space. All I know is that this works fantastic. You just have to be patient for the 3 nights, and you might need something like Liquid Plumber Gel the first time you do this, (and a plunger) if you never did this before, and there is lots of hair, gunk, grease etc. in your pipes, and it takes all of this off your pipes for the first time.
