Wear safety goggles to protect from possible eruption of Lye. Remove standing water. Pour drain opener slowly, directly into drain. Repeat if necessary.


Slowly pour 2 cups directly into drain. Wait at least 1 hour before flushing with hot water. Overnight is best. Instant Power will continue to dissolve hair deposits as long as it is in the drain. If the clog is further down the drain pipe, more Instant Power will be needed to reach the clog.


Always keep bottle on stable, flat surface and hold by handle. Do not squeeze sides. Doing so may cause eruption of liquid. Remove cap by pressing down and unscrewing. Use a sharp instrument to completely remove seal by gently cutting out from the inside of neck. Always replace cap after use. If liquid comes in contact with your skin, refer to first aid instructions.


For the first application use 2-4 cups, if this does not clear the clog use more product.

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.
