Round Stainless Steel & Glass Containers Sets

If the container becomes significantly dented, deeply scratched, cracked or misshapen, it should no longer be used in the microwave.

Damage can create uneven surfaces, which may affect how microwave energy distributes across the container. This can increase the risk of sparking or inconsistent heating.

However, the container can still be safely used for:

• Lunchware
• Fridge and freezer storage
• Meal prep
• Pantry storage
• Oven use (container only)

Yes. Stainless steel transfers heat efficiently, so the container will become hot during use. Always handle with care and use a cloth, tea towel or oven mitt when removing it from the microwave.

• Do not cut food directly inside the container
• Avoid sharp utensils
• Use soft sponges or cloths for cleaning
• Do not use abrasive scrubbers or steel wool

Scratches won’t affect general use, but deep scratches may impact microwave performance.

Lower power settings such as defrost are safe to use and may provide more even, gradual heating.

Higher power settings (up to 1000W) can also be used, but it is recommended to heat in short intervals and stir food between cycles.

Yes. The stainless steel container is oven safe. Do not use the lid in the oven.

Yes. The container is suitable for freezer use. When freezing liquids, leave room for expansion to prevent pressure build-up.

No. The container is made from uncoated 304 stainless steel. This means there are no internal linings or coatings that can wear away over time.

If the container is placed too close to the side, microwave energy may concentrate unevenly. This can lead to:

• Uneven heating
• Localised hot spots
• Potential surface marks

Always position the container in the centre of the turntable.

Yes. Stainless steel may heat food more gradually compared to glass or plastic because it reflects some microwave energy.

For best results:

• Heat in shorter intervals
• Stir between cycles

Using multiple containers or additional metal objects can interfere with how microwave energy moves inside the appliance, increasing the risk of uneven heating or sparking.

If a dented or damaged container is used in the microwave, it can create areas where microwave energy concentrates unevenly. This may lead to sparking (also called arcing).

Sparking can cause several types of damage:

1. Damage to the container

• Burn marks or discolouration on the stainless steel
• Pitting or small surface imperfections
• Further weakening of already damaged areas

2. Damage to the microwave

• Scorching or burn marks on the interior walls
• Damage to the microwave’s internal components over time
• In severe cases, it may affect the performance or lifespan of the appliance

3. Risk to food and safety

• Uneven heating of food
• Localised overheating or hot spots
• In rare cases, sparks can pose a fire risk if left unchecked

• Stop the microwave immediately
• Check that the container is not damaged
• Ensure it is not touching the sides or other metal

Yes, acidic foods such as tomato-based dishes, citrus, or dressings can be used in the container.

304 stainless steel is highly resistant to corrosion and is suitable for everyday use with a wide range of foods, including acidic ingredients.

However, over time, highly acidic or oily foods may cause:

• Light surface staining
• Discolouration or marks

These do not affect the safety or performance of the container.

For best results:

• Avoid leaving highly acidic foods in the container for extended periods
• Wash the container promptly after use
