Customer Reviews for Instant Power 128 oz. Main Line Cleaner

I bought 2 containers of 1 gallons each one in Home Depot and I followed the instructions the exact way in the product directions sticker but it did not work reason why I won’t buy this product gain ended I won’t recommend to any one

Took 2 bottles. 1st I poured in floor drain, but didn't do the hot water step. Didn't work. Poured 2nd bottle in utility sink drain. Next morning, ran the hot water and watched the floor drain. Looked like it wasn't working, then all of a sudden the water sucked down. Very, very pleased that I didn't have to call my ex or a plumber.

I used five bottles followed exactly the way it they said to use it in a week later still was clogged. I went and purchased a 50 foot drain auger underneath the house. Both directions of the pipe was able to free it up. The only reason why bought it because it said it was guaranteed and it did not work.

I used 2 gallons and let it work for 48 hours and it did not resolve the issue.

So for it's working pretty good.

I was not able to drain my mainline completely or avoid using the drains for hours afterwards. Instant Power Mainline Cleaner poured into my clean out cleared the stoppage within an hour. I will purchase another gallon to have on hand.

good product. works well.

It’s a waste money not good at all

Worst drainage product I have ever used.

Effective on stubborn clog

This does nothing. It does perform very poorly. Thanks!

Excellent product at great value. Used it more than 10 years. Easy to use & always effective. Safe for different types of pipes/sewer systems. I use when drainage slows, and once I had to use as emergency as party guests arrived. Now I keep 1 bottle on hand at all times.

I have purchased this this product and the past & I believe nothing works better

Problem solved. Happy Wife, happy life! This product was great.

I had a slow running drain in my laundry tub. I poured the whole bottle down the drain, let it sit for about 8 hours. It opened up my drain to run very fast now. I use this product all the time when needed

Terrible didn’t help me with the problem

I applied 2 gallons, it did not work, I had to call a plumber !
