How to Clean a Microwave Oven with Vinegar: A Simple, Effective Guide

Microwaves are one of the most used appliances in many households. From reheating leftovers to cooking quick meals, they tend to get a fair workout. With that, however, comes mess—splattered food, stubborn stains, and unpleasant smells. Keeping your microwave clean isn’t just about looks; it helps maintain performance, prevents bacteria from growing, and extends the life of the appliance.

The good news? You don’t need harsh chemicals to get the job done. Vinegar is a safe, affordable, and highly effective cleaning solution that can keep your microwave fresh and hygienic with minimal effort.

Why Use Vinegar to Clean a Microwave?

Vinegar, particularly white vinegar, is a natural cleaner that’s tough on grime but gentle on surfaces. Here’s why it works so well:

• It has deodorising properties, helping eliminate strong, lingering food smells.
• It’s antibacterial, making it ideal for cleaning areas where food is prepared or heated.
• Vinegar helps break down grease, stains, and stuck-on food, softening grime so it wipes away easily.
• It’s cheap and chemical-free, making it perfect for households looking to clean naturally.

Step-by-Step Cleaning Guide

Prepare the Solution

Start by mixing 1 cup of water with 2 tablespoons of white vinegar in a microwave-safe bowl (glass or ceramic is best). You can also add a slice of lemon if you prefer a fresher scent.

Steam the Interior

Place the bowl in the microwave and heat it on high for 5 minutes. As it heats, the vinegar-infused steam will spread throughout the interior, softening grime and stains. Once the timer ends, leave the door closed for another 2–3 minutes to let the steam continue working.

Wipe It Down

Carefully remove the bowl—it will be hot, so use oven mitts or a tea towel. Then, using a soft cloth or sponge, wipe down all surfaces inside the microwave:

• Walls and ceiling, especially where splatters collect.
• The turntable, which you can take out and wash separately in the sink.
• The door and seal, areas that often get missed but can hold onto grime and smells.

If you come across stubborn spots, dip your cloth into the leftover vinegar solution and give them a gentle scrub.

How Often Should You Clean It?

How often you clean your microwave depends on how much you use it:

• For frequent use (daily or almost daily), aim to do a quick clean weekly.
• For occasional use, a fortnightly or monthly clean may be enough.
• Spills and splatters should be wiped up immediately to prevent buildup and smells.

Regular cleaning saves time in the long run and helps keep your microwave running smoothly.

Can You Prevent Buildup?

Yes, a few simple habits can help you avoid constant deep cleaning:

• Cover your food with a microwave-safe lid or paper towel to stop splatters.
• Wipe up spills straight away—fresh mess is always easier to clean.
• Leave the microwave door open for a minute or two after use to let moisture escape.
• Keep a box of baking soda nearby (not in the microwave) to help absorb odours in the kitchen.

These steps not only keep your microwave cleaner but also reduce the risk of unwanted smells.

When to Call a Technician

Sometimes, even after a thorough clean, issues may persist. Consider calling a technician if:

• Odours linger despite repeated cleaning—there may be hidden grime or mould.
• You notice discolouration, rust, or damage inside the microwave.
• The microwave isn’t heating properly, makes unusual noises, or sparks during use.
• The door seal is damaged, which can affect performance and safety.

Microwaves are complex appliances, and if something doesn’t seem right, it’s best to have it checked by a professional.\

With regular maintenance and a few preventive habits, you can easily avoid grime and odours, extend your microwave’s lifespan, and keep your kitchen running smoothly. Give it a go—it’s simple, safe, and only takes a few minutes.
