Drain Cleaner

[stephanhodges]

I searched here for the phrase "Drain Cleaner", but wasn't able to find it either here or in Pleco's dictionary, so am asking here.

In the US, I could buy something that when poured into the drain, would clean out the build up of slime, etc. There are also enzymatic versions, if anyone knows how to ask for that too

Try 通渠劑. And also 下水道疏通劑.

The brand I use is simply called 通渠佬.
