Works great!

My sink has been stopped up for far too long, longer than I want to say. I used this plastic stick for clogs idk what it's called, then poured the liquid down the drain. It has unclogged the drain. It smells bad, it steams, it broke down and kinda melted the material that was stuck in the drain, and bubble up what was stuck 🤮. So happy to find something that actually worked bc I didn't want to have to pay a Plummer.

The ONLY drain cleaner that WORKS!

After I tried "Professional Strength" drain cleaner, and my apartment maintenance guy then tried their drain cleaner...my tub was still filling up with water while showering (mid-calf height). I had used this stuff years ago, and really had to search it out - straight-up sulfuric acid - this stuff WORKS - eats/melts the hair clogs like magic (you can hear it sizzle when you pour it in the drain). Tub no longer fills up with water while showering !!! Definite THUMBS UP! (NOTE: It can burn you - be very careful with it - and I close/seal the drain after I put it inside to let it do its thing for about 15-30 minutes... use it VERY sparingly as it only takes a LITTLE (like an 1/8th of a cup). Too much and you will have caustic fumes consuming you bathroom, possibly your house!)

Surprisingly Quick

worked way better than expected. FYI do not flush with HOT WATER!! Read directions and flush with only COLD COLD WATER. Be patient and light some candles away from the drain cause it's gonna give off an odor
