Questions
Frequently asked questions about Lành Lạnh

My fridge smells fishy. What should I do?
Throw out spoiled food, wipe the walls and trays with a damp cloth, keep fish and meat in sealed boxes. Then stick Lành Lạnh inside the fridge to keep removing the odour, with no monthly routine.
Where does the patch go?
Inside the fridge compartment, where the air moves. You can add one on the door as a visible reminder.

How long does it last?
