Heavy Duty Drain Opener is the economical treatment for bathroom and kitchen drain clogs.
This is a strong non-acid formulation, 10 times stronger than common drain openers.
We recommend that Heavy Duty Drain Opener be allowed to stay in the drain overnight.
The longer it remains in the drain the more drain clogging matter it will dissolve.
