Anything from egg shells, meat, fat grease, and even fruits and vegetable easily get tossed inside of the sink disposal and if this disposal is not properly ran after depositing this food into it, it can lead to an array of odors within this drainage that will taint the indoor space of your kitchen, in some cases. Odors like musty, moldy, and mildew smells can develop in your garbage disposal and this can lead to worry and concern from homeowners who will begin to smell what they believe is a mold smell in their home.

Any time there is even a comparable scent to that of mold present in a home, most people will begin to do their due diligence to determine if there is mold growing in the home. However, after investigating you determined that the mold smell originated from directly in your garbage disposal in your sink’s kitchen – what could be the cause of this mold smell and how can you remove it completely?

In this article we are going to learn more about garbage disposals and why they can sometimes take on the odor of mold, along with determining what the best deodorizer is for your home’s garbage disposal for any kind of smell including mold.  

How Do Garbage Disposals Work

How Do Garbage Disposals WorkHave you ever stopped to consider how a garbage disposal works and its main purpose within your kitchen’s sink? Many of us will be well aware of what garbage disposals can do when it comes to chewing up and removing food scraps down its drain, however, there is more to this disposal than what many know. Although a garbage disposal seems to work like a blender, expect for the fact that this disposal does not contain blades, rather it has impellers or lugs that are mounted on a spinning plate. These impellers will continually work to force food waste particles against a stationary grind ring that will help to break down the food waste into very small particles, and eventually liquifying them. Once it become liquified it will be flushed by the running water from the sink and the particles will be pushed through the grind ring and out of the disposer into the waste pipes.

Unfortunately, like any other appliance there are problems that can occur with a garbage disposal that will lead it to get jammed or burnt out. These problems will happen when people put things down this disposal that it can’t handle, and thus it is important to be vigilant when it comes to determining what can and can’t be put down this drain.

What Not to Put in Garbage Disposal

When it comes to classifying what items are harmful and potentially damaging to your sinks garbage disposal it can be difficult to distinguish between something safe and alternatively something that is not safe to place down your garbage disposal. As we discussed previously, often times when we throw items down our garbage disposals we rarely think twice before doing so, which can potentially cause major problems in your disposal when the wrong items find their way down your drain. You may find that some items that you put down your drain all too often are some of the worst culprits behind damage caused to this appliance, and therefore it is necessary to know exactly what you can and can’t place down your sinks drain.

  • Grease, Oils, & Fats: After cooking on a pan you may be inclined to take the remaining grease left on the pan and dump it down your sink drain but wait just a minute! Grease, oils, and fats are all items that could lead to the clogging of your garbage disposal.
  • Egg Shells & Onion Layers: Onion layers and eggs shells have a film-like membrane that can wrap around moving parts and lead to damage when they come into contact with the garbage disposal.
  • Nuts & Nut Shells: Nut shells are very hard and while some can easily maneuver these items, other garbage disposals will have a difficult time breaking down the nuts and their shells.
  • Coffee Grinds: Coffee grounds may not be horrible for your garbage disposal but when it comes to your plumbing it can have quite the effect. These grinds will eventually settle like sediment in your plumbing and will essentially increase the likelihood of clogging in the plumbing pipes.
  • Animal Bones: Bones are obviously a no-go when it comes to your sink’s garbage disposal, as it is one of the hardest naturally occurring substances. It is a general rule of thumb to never put down bones in the disposal as it can break it and lead to a major clog that can cause problems like odors in the sink.
