Tableau Bathroom Drain Unblocker uses eco friendly enzymes to unblock shower and bath drains. It will dissolve soap scum, fat deposits and hair 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 enzymes will work away to clear the blockage. Retreat the drain periodically to keep it odourless and free flowing.
