If you can hear mice running around the rafters of your house, sometimes simply getting rid of the mice with traps is the easy part. The urine left behind can be particularly pungent and far more unpleasant than the sight of mouse droppings in your cabinets. With a few household items, diluting and clearing that odour can be achieved without purchasing any fancy or harsh chemical solutions, saving yourself some dollars in the process.
Purchase a spray bottle at your local goods store (they shouldn't be more than a couple of dollars), or rinse out and reuse an old cleaning spray bottle.
Fill the spray bottle three-quarters with a 2:1 ratio of water to vinegar.
Add a tablespoon of baking soda to the mixture. Mix the solution together and fasten the spray top on.
In large sweeping motions, apply the solution to the affected areas. The vinegar and baking soda soak up the smell. Allow the solution to dry and repeat as necessary. It may take several applications, depending on the potency of the smell.
Leave out small bowls of vinegar near the affected area if it cannot be easily hit with the spray application.
Additionally, you can sprinkle baking soda over the affected area and allow it to sit for a couple of hours before vacuuming.
Urine, mouse or otherwise, is a particularly pungent odour. Don't be discouraged if the smell lingers after a single application. Repeated use will continue to chip away at the smell. The solution should be fine for most household furniture and appliances, but just to be safe, consult the manufacturer's website.
