Love Mother Earth

When it comes to our planet, we love it as much as we do a clean drain. That’s why we created this specially formulated blend of microbial enzymes that do a great job of gobbling up all the goop.

Family comes first

Our ECO Clog preventer is safe for families, pets and the earth. The reason? We use enzymes that quite literally eat all the gunk. We use no caustic chemicals in our ECO formula.

Super-charged microbial blend

When we say supercharged, we’re not kidding. We have 4 times the amount of enzymes than any other formula. That means we are very effective in keeping your drains clean and free-flowing.
