Does the job.

The Instant Power crystal lye drain opener is extremely effective for clearing tough clogs in bathroom and kitchen drains. This sodium hydroxide formula works quickly to break down grease, hair, soap buildup, and other common blockages without needing constant repeat treatments. I followed the directions carefully, and the results were noticeable in a short amount of time the water began draining freely again with no lingering slow flow. It’s especially useful for sinks, shower drains, and pipes that have stubborn buildup that regular liquid cleaners can’t handle. What I appreciate most is how strong and reliable this product is when used correctly. The crystal form allows for controlled application, and a small amount goes a long way, making the one-pound container last for multiple uses. It feels like a professional-grade solution rather than a watered-down household cleaner. As long as safety instructions are followed, it’s a very dependable option for serious clogs. Overall, this drain opener delivers powerful performance, saves time, and helps avoid expensive plumbing calls, making it a great product to keep on hand for household maintenance.

This drain opener is a dependable go-to whenever I have a clog. I’ve used it a few times now, and it clears the drain every single time. It works quickly, just pour it in with hot water, wait 15 to 30 minutes, and the blockage melts away, whether it’s hair, grease, or soap buildup. What I like most is the consistent performance. It’s a compact bottle that packs a punch. I’ve used it on kitchen sinks and shower drains, and each time it renews flawless drainage without any fuss. If you are looking for a professional-strength cleaner that’s easy to use and actually works, this one is a smart choice. It’s practical, effective, and has earned a permanent spot in my cleaning supplies.

Multiple bottle of Drano did not help. However, this product, pure lye, fully cleared the clog in my wash basin using only a small fraction of the container. No funny business or marketing here, just pure soda.

I kid you not, you can use it to fix your old engine if you have aluminum transfer on the bores. Put it on some paper shop towels and press it against the aluminum deposits. It will etch them off like butter in the sun. ONLY do it if your block is cast iron though. It will leave the cast iron in original shape. I attached one before and one after picture of my engine bore. After pic is after a tiny little honing by hand. It measures and looks like new after 200k miles on the engine. BE CAREFUL though because it will etch off ANY aluminum or other metals than steel or iron it will come in contact with. So keep it away from other aluminum parts!
