Getting rid of smell

[Pandu Chimata]

Hello Team, i am about to buy a property that is has very very strong smell inside. It looks like several cats were there for a long time. Unless I clean the smell, we cannot work there. 

Currently all the doors and windows are closed. How do I get rid of the smell? I am sure many of you folks have gone through this situation. Thoughts?

Try an ozone machine.  They are inexpensive and you can get them on amazon. Make sure no one is in the property while the machine is on.
