I have a very slow draining bathroom sink and went out to purchase a drain cleaner. I try to use products now that are non-toxic, or at least not as bad for the environment. I found DrainOut and it is listed as a non-toxic product that will clean tough blockages and freshen the drain and pipes.
It is supposed to work within 15 minutes. Well I am currently 1 hour in and it has cleared nothing. Not only has it not cleared the drain, my sink has gone from slow drain to no drain.
The scent is not a chemical one, it simply smells like a cleaner, with a slight plastic smell. It also is not bothering my eyes or nose, which is good.
Maybe it would work for less clogged sinks, but not this one.
