Zep Drain Defense Enzymatic Drain Cleaner Powder 18 Ounce

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!

Helps keep drains clean and definitely reduces floor basement drain odor than other products I've used. House was built in 50s and my basement drain always has an odor. I put vinegar and baking soda down it regularly, but this has helped tremendously!

So happy to find a product that actually gets rid of those pesky, tiny drain flies. One scoop mixed with warm water in an old mayonnaise jar & no more problems!

I use this monthly at night before I go to bed to keep my drains running free. Has been an improvement in reducing buildup in my pipes. I prefer the enzymatic preventative approach to using harsh drain openers and I have had success with keeping the drains running well.

I have used Zep drain cleaners for years. Excellent product.
