After reading the reviews, I came to realized that this product might not work on standing water. So, I bought the product and I made sure to use it when the water level was below the drain level. I didn't have a complete clog. The water still drained, but very super slow. I used about 3 ounces of the Liquid Lightning and waiting the 15 minutes, then ran the water. I ran the water slowly to make sure it didn't come out the drain, I didn't want to ruin the tub finish. I noticed that the water came up and wasn't going down fast enough, so I waited until it went down far enough and I tried it again 3-4 ounces in the drain. Oh, and I used a funnel to do this to make sure nothing fell on the finish. This last wait time was about 30 minutes because I got caught us with dinner. When I went back to check the tub, I turned on the water slowly and the water never came up again. I then turned it up full blast and the water drained faster than it ever did. I love this product and I totally recommend it to anyone!!

I had to use it twice, but it worked! Had been plunging for hours. Drano did not work. Snaked the drain. Dish soap and boiling water method did not work this time. Definitely effective!

I absolutely LOVE this product!!! I first used it in my tub because it was draining slow and it cleared it right up and I haven't had any issues of slow drainage since. The second time I used it was for my bathroom sink because it was draining slow... once I used the liquid lightening it cleared it right up. I will continue to use this product as long they keep it on the shelves.

Being a mild germaphobe, I do not own a plunger and never intend to. So my spare bathroom had a clog for 4 days that would not drain for any reason whatsoever! I had just had a plumber over a month ago to make sure my washer was properly installed and he found some more issues that he had to fix and it had cost a pretty penny, so I was very worried that I would have to call him again. Online, I found suggestions for baking soda, hot water, dish-washing fluid, tried them all, NOTHING WORKED! I waited 4 days for the plug to work itself out as water slowly drained past it, but no such luck. Being near tears, and ready to throw dynamite down the thing, I went to Wal-Mart and five dollars and some change later, I poured the liquid lightning slowly down the almost over-filling toilet, and just as I was getting to the bottom of the bottle, walla! I heard a trickle, trickle, trickle, and then swoosh! Everything went and I was standing there like, "Oh my goodness! NO, THAT DIDN'T HAPPEN IN FRONT OF MY EYES!" But it did! THIS IS THE BEST THING OUT THERE (If it destroys my pipes, I'll be back here to report it, but for now, it worked PERFECT, PERFECT, PERFECT!). I can't say enough about this!

  • A. • You could try the Liquid Lighting product after you carefully coat the bottom of your tub with vaseline and preferably remove the metal drain fixture. Remember this is very caustic acid. • I certainly would first try a less dangerous liquid or powered drain cleaner first. Other options, if the liquids don't work: • If you have access to the local bathroom "cleanout"; purchase an inexpensive drain auger (snake) and use it down the cleanout. • If you can't find the cleanout, get on your roof and find the plumbing vent for the bathroom and run the snake down from the roof. • You can also try a garden hose down the vent or cleanout, if it has some good pressure. • The next step would be to rent an electric drain cleaner snake from a local rental yard and try the same. Be aware, you may not have an internal clog. Often times, roots will find your drain lines and invade them. You may cure the problem for a few weeks or months; yet eventually you will have to dig up the drain line, remove all roots in the area (and maybe the tree as well), then replace the bad section of pipe. A plumber can sometimes put a camera down your lines to see what's going on. Clogged drains are no fun. Good luck.

  • A. I had a similar issue.Like with me it's most likely a clog in the main line.And since all the drain lines tie in to it that would make the water come up the tub since the sink is higher up.The clog may be after your tub.I would follow the directions and start with he tub.I had a clogged toilet drain and plunging the toiled made the water come up the vanity sink drain.I poured "Drain Lightning" down the toilet and waited the time in the directions and the darin was cleared.
