Find all soiled areas – a black light will show even old stains.
Clean the areas with an enzyme cleanser specially formulated for pet
urine and feces.
Make these areas unattractive or unavailable to your pet.
Make the appropriate bathroom area attractive by keeping it very
clean, choosing a better location for your pet, etc.
Teach your pet to use this place by using positive reinforcement
training techniques and close supervision or confinement. Be patient.
Cleaning methods to avoid
Steam cleaners permanently set in the odor.
Chemicals, especially ones with strong odors like ammonia or vinegar,
may encourage your pet to mark over the odor.
Cleaning washable items
Machine wash adding either baking soda or enzymatic cleanser (read
instructions carefully).
While training, cover your belongings with vinyl, plastic or anything
easy to clean and that's unattractive to your pet.
Cleaning carpets & upholstery
Soak up as much of the urine as possible.
(Place a little of the soaked paper in the designated “potty” area to
encourage your pet to go there.)
Rinse with cool water and remove as much of the water as possible
(also remove any other traces of cleaners used before as they can
neutralize the effect of the enzymes).
Use the enzyme cleansers following the manufacturer's directions and
always test them in a hidden area first.
