work as well as it can. i had to hydrojet my lines though, it may be good if your doing maintenance but in my case i had 30lbs or so of grease so lye or other chemicals just won't do much. best way to mix this stuff up is to make a solution in a glass bowl then poor the solution down the drains. do not just pour it down the drain as it will produce incredible heat and damage the slip nut washer. also will precipitate out and adhere to the bottom of the trap causing more problems. don't use in zinc or stainless steel as it makes toxic gases.

Sprinkle it on the clogged area and pour 1 liter of very hot boiling water over it. It worked really great. The water flow in my bathtub was very low before, but after using this product the drainage improved a lot. I’m very satisfied with the result.

Good item

Shower was draining super slow. Drain snake and draino did NOTHING. This cleared the drain in Lee's than an hour.

No matter the clog that slows flow to a trickle this product is effective used as the directions state. Ver pleased. Be cautious around pets and kids! It's caustic of necessity to work.

This stuff works great. It broke up a persistent clog pretty quickly, and now my drains are working like new again. Simple to use and very effective. Glad I tried it.
