You could use this to get out the normal buildup of soap and gunk in your sinks or toilets (or as a preventative) but it really did not take care of a stop-up--that calls for the big guns!

It was really great to purchase something that actually works!!!!
Def going to look into more products!! 10/10

Let it sit for 6 hours did nothing- wheres the 100% garentee?

Although it's only one small package this stuff packs quite a powerful punch to stubborn clogs! Yet it's totally safe to use in toilets. I had a severely clogged loo and after having tried and failed with a number of other products I was almost ready to do the forbidden and put some Liquid Plummer down there even though every lable I've read told me not to. I was desperate as this is the only water closet in my home! But I read the glowing reviews of others and took a chance. I wasn't disappointed.
Unlike many other drain openers that use enzymes this stuff doesn't need you to do any premixing in warm water to activate it. You just pour it in and please use the WHOLE PACKAGE to get the best effect. The first thing you'll notice is a terrible smell as the stuff starts working. Make sure you have PLENTY of ventilation and couple of cans of air freshened wouldn't hurt either..lol
It's best to let the Green Gobbler work undisturbed overnight and after at least 12 hours simply flush your loo to get things back to normal.
I'll be buying several more pack to keep on hand. At around $10.00 including shipping it's a whole lot cheaper than calling a plummer just to unbung the loo.

Didn't make any difference. I used in toilet.
