Where is that odor coming from in the kitchen?

There have been so any times that I enter a home and there is a weird odor that gets more prominent as you walk into the kitchen.  I look around and the home is clean, sink empty and clean, no food or garbage is noticeable.  What could that smell be?
 
In south Florida, sink disposals are in almost every kitchen.  You use it regularly and probably rinse it after every use, but there always seem to be an odor emanating from it and you cannot figure out why.  Let me explain.
 
When you use your disposal, there are always remnants of food particles that adhere to the underside of the rubber and to the metal neck (upper part) of the disposal right beneath the rubber.  No matter how many times you rinse or clean your disposal, the odor will not leave.
 
Here are important tips to rid your disposal of any odor and keep your home smelling fresh and clean.  These can also help you avoid a potential blockage in your disposal which could lead to water damage to your kitchen cabinets:
 

1. When using your disposal, always use hot water. This will help to eliminate any residue from foods cooked with oil.
2. Clean your disposal after each use with a mild cleaning solution of your choice along with hot water and rinse thoroughly. 
3. This is the most important part!  You must always clean the underside of the rubber and metal neck of the disposal and rinse thoroughly with hot water.  DO NOT turn the disposal on during this process.  This is the key to removing any excess food or oily residue and will keep your disposal fresh and odor free.

 
Always stay safe while cleaning your disposal and do not place your hands down into the main part of the disposal.  Wishing you a safe and happy holiday.
