Unfortunately, one thing that many dogs seem to pee on is the air conditioning units outside of the home. When they do this, your home can fill with the disgusting smell of dog urine each time your air conditioning unit kicks on to cool your home. Here, you will learn how to clean the dog pee off of your air conditioning unit.

To clean the dog urine off of your air conditioning unit you will need:

  • Screwdriver
  • Hose and nozzle
  • Enzyme-based urine cleaning solution with spray bottle

Cut the Power

Start by cutting the power to the air conditioning unit. Failure to do so increases the risk of electrical shock as you clean the unit.

Remove the Grill

Use the screwdriver to remove the screws holding the grill on the unit. If the screws will not easily turn, spray them with a little bit of rust breaking spray and let it sit for a few minutes. You want to remove the screws without stripping them, so that you can put them back in place easily when you have completed the cleaning. Once the screws have been removed, carefully lift off the grill and set it aside.

Apply the Cleaner

Now that the internal coils are exposed, spray the unit with the enzyme-based urine cleaning solution. Be sure to take your time as you apply the solution, because you will not be doing any scrubbing to get the areas that are missed. This solution works to target the protein that is in the dog urine that causes the odors.

Once you apply the cleaner, you have nothing further to do until the cleaner has completely dried.

Rinse the Unit

Now that the cleaner has dried and killed the proteins in the dog pee, you are ready to rinse it all away. Use your garden hose set at a medium pressure setting to spray the unit. Be careful as you spray the internal components so that you don't knock any wires and connections lose.

Finish Up

Put the grill back on the unit, power it up and give it a test. Do you still smell the odor? If so, you will need to repeat the above steps until the odors are no longer an issue.
