PEQUA INDUSTRIES Pequa Heavy Duty Drain Opener, Non-Acid, Fast-Acting Formula, Industrial strength Drain Cleaner for Sinks, Tubs, Septic Tanks - 32 Oz (Pack of 2)

This is not your average store-bought drain cleaner—this is industrial-strength, and it works accordingly. I used this on a slow/clogged drain that typical over-the-counter products couldn’t fully clear, and the difference was noticeable. It cuts through buildup (especially grease and hair) quickly and restores flow much more effectively than milder solutions. That said, this is a serious chemical (potassium hydroxide), and the warnings on the bottle are not exaggerations. You absolutely need to use proper care—gloves, ventilation, and careful pouring. This isn’t something you casually splash around, and it’s definitely not for use with other chemicals. A few things I appreciated: It works fast and doesn’t require repeated treatments No gimmicks—just a straightforward, effective formula Good value considering how little you need per use Important notes: Follow the instructions exactly Do NOT mix with anything else Keep it stored safely (especially around kids/pets) If you’re dealing with a stubborn clog and want something that actually gets the job done, this is a solid choice. Just respect what you’re working with, and it will do exactly what it promises.

The absolute best product for drain cleaning. My shower drain gets clogged easily even though I have a cover to collect hair. Well this product does smell and is harsh. It works perfectly. The clog Removal is superior.

Love love love. A plummer recommend this because we had a slow drain. Snaking it and using a camera was close to $1000. We used it as directed and it works. Happy person

Cleared fully clogged bathroom pipe of mucky substance

I was skeptic, but I was desperate. This is amazing. My bathroom sink has not worked properly for months. I tried other things and it was still stuck. I use this product today. Three hours later. Everything was perfect.

Nothing works better than this!

It works better than all the others I’ve tried. But it doesn’t clean the drain to the point water runs fast down drain. I used a whole bottle let sit for hours.

This stuff works but I’d be careful using it if you don’t have newer PVC pipe.
