Plan on deep cleaning the garbage disposal weekly with a maintenance run of ice cubes and lemon peels. Make it a regular part of your kitchen cleaning checklist.

If you don’t want to remove the sink stopper, pour ½ cup of baking soda and 2 cups of boiling water down the drain. Start by pouring 1 cup of boiling water, then the baking soda, followed by the remaining cup of boiling water. Use caution as boiling water can damage PVC or other plastic piping. Using a scrub brush or slightly abrasive sponge, clean the top of the stopper, and run the faucet to ensure the drain is clear and the stopper is clean. 

Ideally, you should do a cleaning once every week. Make your fridge cleaning a part of your weekly Sunday chores, if possible. This will prevent bacteria from breeding and help your fridge work more efficiently; spilled food can cause food to build up near the fridge vents, which forces your fridge to do more work to stay at an optimal cold temperature.

To hire a professional house cleaner, start by searching for local services online and asking friends or colleagues for recommendations. Review company websites, social media accounts, and online customer reviews to understand their business and reputation. Contact prospective cleaners to ask about their services and charges. It's also a good idea to meet with them in your home so they can see the scope of the job, allowing you to discuss expectations and negotiate a price. Always do thorough research before choosing a cleaning service to ensure it’s the right fit for you.
