Review: High purity, perfect for soap making - This pure sodium hydroxide is exactly what I needed for making soap. The beads dissolve quickly and consistently. 99% purity ensures reliable results every time. The container is well-sealed and includes proper safety warnings. Works great for drain cleaning too when used properly. Much better quality than what you find in stores. Excellent product for soap making enthusiasts!
Review: AMAZING PRODUCT!! WELL WORTH THE PRICE!! - I was amazed how this product worked on my slow moving bathtub/shower drain! I had tried snaking it, plunging it, liquid drain cleaner...nothing helped until this. I watched the videos people posted and thought what the heck, I'll give it a try. Ran hot water for a minute, waited 10 minutes, poured 1/4 cup directly into the drain, added more hot water, saw 1 bubble (burp) waited, repeat ran hot water 1 minute, 10 minutes later added the beads, little more hot water...finally drain opened up completely. Will use as a monthly maintenance to keep functioning.

## Features

- 99% PURE SODIUM HYDROXIDE: Our industrial-strength formula is the purest white, bead-size lye available. This professional-grade sodium hydroxide is designed to dissolve grease, hair, and root growth instantly, making it the ultimate drain opener for stubborn clogs.
- THE SOAP MAKER’S FAVORITE: Crafters prefer ComStar Pure Lye for its unique bead shape that dissolves quickly and won't clump or create static. Whether you are a beginner or a pro, these small beads make soap making faster, easier, and more consistent.
- ECO-FRIENDLY & BIODEGRADABLE: Clean your drains without the guilt. Our non-acid, biodegradable formula is safe for septic systems, cesspools, and grease traps. It even enhances the growth of active bacteria in your septic system when used regularly.
- SAFE ON FIXTURES & PIPES: Unlike harsh acid cleaners, Pure Lye is safe on fine fixtures, chrome trim, and all types of metal or plastic (PVC) pipes. It is odorless and creates no offensive fumes, making it ideal for use in homes, schools, and hospitals.
- UNIQUE BEAD TECHNOLOGY: Because of their specific density and shape, these beads sink through standing water to attack the cause of the blockage directly at the bottom of the pipe for a fast, effective break-up of grease and organic matter.

### ⭐⭐⭐⭐⭐ It will clear your drain
*by S***T on September 9, 2025*

I have four bathroom vanities, one kitchen sink (open drian and garbage disposal sides) as well as a utility sink. In addition to multiple shower drains, a soaker tub drain and a jetted garden tub drain. It's easy to see that with all of these drains, something will eventually need your attention. Sink drains provide relatively easy access to the trap and with a modest amount of effort they can be cleaned out manually. If however the clogg goes far beyond the trap the repair gets a little more intense. Of course shower and tub drains typically don't have easy access to their drain plumbing. This is the answer for these scenarios. Not only will it open up the drains, it will do so quickly and as an added benefit it will help to keep things downstream from clogging in the first place. I have also found that it works well in laundry drains where soap scum and fabric softener buildup can become problematic. It can be used preventatively in utility drains such as HVAC A Coil condensate drains. Who wants to find their AC system shutting down because the condensate tray is backing up? Or worse yet, find out that the system didn't shut down but instead overflowed onto your carpet, hardwood or even worse, into your ceiling if the unit is upstairs or attic located. This stuff works well for opening clogged drains quickly and preventing clogs when used as a maintenance aid. I typically by this in either the large container or in two packs as I want to have it on hand when needed. I also restock quickly when low.
