I really like this drain cleaner for many obvious reasons. It does everything the bottle says it will and I am extremely happy that it is not toxic. You can use it on a slow drain or for regular monthly maintenance to get rid of scum and buildup etc.
Just follow the very simple directions.
It has a really nice smell ~ which is an added surprise! Very reasonably priced and safe for your home and family.
