What Not to Put Down Your Garbage Disposal

In Honolulu, garbage disposals are a convenience many homeowners rely on for handling kitchen waste. However, improper use of these appliances can lead to costly plumbing issues and even environmental problems. Understanding what not to put down your garbage disposal can help you protect your home’s plumbing system and comply with local waste management practices. 

• FOG Is A Recipe For Disaster: Pouring fats, oils, and grease (commonly known as FOG) down your garbage disposal might seem like an easy cleanup solution, but it’s one of the worst mistakes you can make for your plumbing. These substances go down in liquid form but quickly cool and solidify inside your pipes, creating sticky buildups that trap other debris and lead to stubborn clogs. Over time, these blockages can result in costly plumbing repairs and even sewer overflows that affect entire neighborhoods. In Honolulu, where proper waste management is vital to preserving the environment, improper disposal of FOG can also contribute to pollution of local waterways. Instead, collect FOG in a heat-safe container, allow it to solidify, and dispose of it in the trash to avoid plumbing disasters and support sustainability.  

• Hidden Diary Hazards: Pouring milk, cream, or yogurt down the drain might seem harmless, but these dairy products can cause problems in your plumbing system. As dairy decomposes, it produces a sour smell and releases fats that can coat the insides of pipes. This fatty residue traps other food particles, leading to blockages. In the warm climate of Honolulu, decomposing dairy can also contribute to faster bacterial growth within your pipes. Instead, dispose of spoiled dairy products in your trash or compost them if appropriate.

• Stringy Fruit Peels: Banana peels, mango skins, and pineapple tops may seem like they’d break down easily, but their fibrous texture can wreak havoc on garbage disposals. The stringy fibers can entangle the blades, jamming the motor and creating an expensive repair situation. These tough peels are better suited for composting, where they can break down naturally and enrich your soil. If composting isn’t an option, dispose of them in the trash to avoid unnecessary strain on your plumbing system.

• Citrust Peels: While some people think citrus rinds like orange, lemon, or lime peels can help clean and deodorize a garbage disposal, they often do more harm than good. Thick citrus rinds take time to break down and can jam the blades or create a sticky residue in your pipes. Additionally, the oils in citrus peels can corrode parts of the disposal over time. Instead, use a vinegar and baking soda solution for natural deodorizing, and compost your citrus rinds if possible.

• Wet Wipes And Paper Towels: Not As Flushable As You Think: Despite marketing claims, wet wipes and paper towels are not suitable for garbage disposals—or any part of your plumbing. These products do not dissolve in water the way toilet paper does, leading to blockages in your pipes. Honolulu’s waste management system is designed to handle organic waste, not synthetic materials like wipes. 

• Shells And Bones: Whether it’s pistachio shells, peanut shells, coconut husks, bones, or even eggshells, these hard or fibrous materials are far too challenging for a garbage disposal to handle. Nut shells and coconut husks can dull or chip the blades, while their fibrous nature may jam the motor entirely. Bones, whether from chicken, pork, or beef, are even harder, causing significant damage to the disposal and potentially breaking the motor. Eggshells, while seemingly harmless, have a thin membrane that can wrap around the blades, hindering their movement, and the fragmented shell pieces can mix with grease in the pipes, forming stubborn clogs. The best way to dispose of these items is to throw them in the trash or add untreated, natural ones to your compost bin.

• A Sticky Situation: Dumping flour, dough, or batter into your garbage disposal can lead to one sticky mess. These ingredients combine with water to create a glue-like paste that sticks to the disposal blades and lines the insides of your pipes. Over time, this buildup reduces water flow and causes clogs that are difficult to remove. Instead of rinsing dough or batter down the drain, scrape it into the trash and wipe your mixing bowls clean with a paper towel before washing them.

• Bad Smells And Big Problems: Fish skins, shrimp shells, and crab legs might seem harmless, but they’re a big no-no for garbage disposals. These materials don’t break down easily and can clog the blades or pipes. Additionally, seafood waste decomposes quickly, creating strong odors that linger in your kitchen. To avoid a smelly and costly plumbing issue, dispose of seafood waste in the trash or use it in compost if appropriate.

• A Costly Mistake: Occasionally, small metal items like bottle caps or twist ties accidentally end up in garbage disposals. These items can severely damage the blades and motor, often requiring the entire unit to be replaced. Not only do they create an immediate problem, but fragments of metal can also get lodged in your pipes, causing further complications. Double-check your sink before turning on the disposal, and ensure these items go in the recycling bin instead.

• Pet Food: Wet pet food or kibble often seems like an easy item to rinse down the garbage disposal, but it can cause serious issues. Wet food forms a thick paste when broken down, and dry kibble expands as it absorbs water, creating blockages in your pipes. Additionally, the oils and fats in pet food contribute to the same problems caused by FOG (fats, oils, and grease). Scoop leftover pet food into the trash to keep your plumbing in top shape.
