September 27, 2025A smelly garbage disposal is one of the most common complaints we hear from Melbourne homeowners. In most cases, it’s not because the unit is broken, but because it’s not being looked after properly. Hence, we highly recommend regular garbage disposal maintenance
To keep your garbage disposal running smoothly, think of it as a mini version of a plumbing maintenance service. A little effort here and there goes a long way toward extending the lifespan of your unit, preventing clogs, and keeping those nasty odours at bay.
In this guide, we’re going to walk you through 10 simple but effective garbage disposal maintenance tips you can start using right away!
7 Garbage Disposal Maintenance Tips
Honestly, most of these steps are easy, cost next to nothing, and make a huge difference over time.
Remember, looking after your disposal is not just about convenience. The benefits of plumbing maintenance include fewer breakdowns, fewer calls to plumbers, and a system that lasts years longer than one that’s ignored.
Here’s your quick-start guide to keeping your unit in top shape:
1. Run Cold Water Every Time
Always run a steady stream of cold water before, during, and after using your disposal. Cold water helps solidify any grease or fat, so the blades can chop it up before it sticks to your pipes.
2. Avoid Throwing Coffee Grounds
We know it’s tempting, but coffee grounds in garbage disposal units are a recipe for clogs. They clump together like wet sand and can quickly jam your system. Toss them in the bin or add them to your garden instead.
3. Cut Waste into Smaller Pieces
Don’t shove large chunks of food straight into the disposal. Instead, we advise you chop them up or break them down before feeding them in. This makes it easier for the blades to grind them and reduces the risk of jams.
4. Keep Fats, Oils, and Grease Out
Grease may slide down as a liquid, but it quickly hardens in your pipes. Over time, this leads to stubborn blockages. Dispose of fats and oils in a jar or container instead of pouring them down the sink.
5. Freshen Up with Citrus Peels
Does your garbage disposal smell weird? Simply pop in some lemon or orange peels while running cold water. The natural oils in citrus act like a deodoriser, leaving your disposal smelling fresh.
6. Use Ice Cubes for a Blade Tune-Up
Drop in a few ice cubes and turn on the unit. The cubes will help knock away those stuck-on foods while giving the blades a quick clean.
7. Set Up Regular Check-Ups
Your disposal, like any other appliance, could use a professional checkup every now and then. If you include your unit in a regular plumbing maintenance service, you can catch small problems early, which will save you time and money in the long run.
Why Should You Maintain Your Garbage Disposal?
Now that we’ve gone over the most important maintenance tips, let’s talk about why they matter. You could call a garbage disposal a hard-working appliance that eats up food scraps every day.
So, if you don’t take care of it, it can quickly become a source of annoyance with bad smells, poor performance, or even breakdowns.
Think of your disposal as a car engine. Things will start to go wrong if you don’t take care of it. Just like not getting your car checked out regularly, not taking care of your garbage disposal can lead to a backed up garbage disposal, water pooling in the sink, or expensive plumbing repairs.
Here are some of the most important reasons why regular maintenance is so important:
- Stopping blockages. Over time, food, grease, and other debris can build up. This means that water has nowhere to go, and all of a sudden you’re standing over a washbasin that won’t drain. Keeping your disposal clean and free of buildup lowers the chance of getting bad clogs.
- Adds years to its life. If you take care of it, a garbage disposal can last for 10 to 12 years. Flushing with hot water or staying away from the wrong foods are easy things you can do to keep the motor and blades in good shape, which will save you money in the long run.
- Reduces smells. Nobody wants a kitchen that smells like rotten food. Regular cleaning and flushing helps prevent bacteria from growing inside the unit.
- Improves its efficiency. If you keep your disposal clean and in good shape, it will grind up food waste better. That means fewer problems, smoother operation, and less stress on your plumbing system as a whole.
- Saves you from emergencies. You don’t want to be caught off guard by a major clog or disposal breakdown, do you? Regular garbage disposal care will come in handy for minimising sudden issues, like having to spend money on urgent plumbing services when you least expect it.
FAQ About Garbage Disposal Maintenance
Now, we’ll answer some of the most common questions homeowners ask, along with clear answers to help you stay on top of disposal care:
1. What is the average life of a garbage disposal?
A garbage disposal usually lasts between 8 and 12 years, depending on how often you use it and how well you take care of it.
If you clean your unit regularly and don’t put things like grease or bones down the drain, it can easily last longer than that.
2. How to deep clean a garbage disposal?
Start by turning off the power for safety, then scrub the rubber splash guard with a brush and dish soap as it often traps odours.
Next, grind up a mix of ice cubes and rock salt to help dislodge stuck-on food inside the chamber. For an extra fresh finish, toss in lemon or orange peels while running cold water. This helps remove gunk and leaves your disposal smelling clean.
3. Should you service your garbage disposal?
Yes, they don’t need to be serviced by a professional very often, but it’s a good idea to have them checked every so often.
So, the moment you start hearing strange noises from your disposal or that it gets stuck a lot, then it’s your cue to have it checked out.
Conclusion
There are so many benefits from maintaining the cleanliness of your garbage disposal. It helps prevent clogs, extends the life of your unit, and keeps your kitchen problem-free.
