Tableau Kitchen Sink Unblocker uses eco friendly enzymes to unblock kitchen plugholes and drains. It will dissolve, fat deposits to leave drains fresh and clear. It is non-caustic, acid free, safe in septic tanks and biodegradable.
Just pour the unblocker down the plug before bed and while you sleep the eco enzymes will work away to clear the blockage. Retreat the drain periodically to keep it odourless and free flowing.
