If I am not mistaken, it is for kitchen fat. That stuff is never going to melt hair!

BTW, what is it that's clogged? Kitchen sink? Bathroom floor-drain hole?

you should go to ace hardware, and buy drain opener.

Ace hardware sells many of them. The best one is "i forgot the name"... but i recalled from all the collection, it has plastic bag sealed wrapped the sealed bottle... all drain opener are liqued, stored in sealed bottle. this one lagi best, it has plastic sealed wrapped outside sealed bottle... the bottle is white, the brand written in red / black printing. and it has word "professional grade"... sure will not miss lah..

"the guy that recommend me the stuff there doesn't sound like he ever use it before."

Better double confirm before buying. I bought 1 from hardware shop, the guy say can be use on PVC pipe. I used and the PVC pipe all melt.

I cannot find Rooto at ACE. Got any other rexommendation?

i tried cheapo liquid type from hardware shop, kenot work

then the best is the imported gel type from ACE hardware

Try this one

which method/material did you end up using to clear the blockage?
