Experts and consumer organizations have issued warnings regarding common household habits that may damage kitchen appliances or create safety hazards.

Initial warnings focused on microwave safety, specifically advising against using the tops of microwave ovens for storage. Experts noted that placing items such as cookbooks, paper towels, or plastic packaging on the device can obstruct ventilation openings. This lack of airflow can lead to overheating, electronic failure, or increased fire risks.

Subsequent reports expanded these warnings to include oven maintenance. The British consumer organization Which? highlighted instances of oven door glass shattering, suggesting that the use of abrasive cleaners can create microscopic scratches that weaken the glass during heating and cooling cycles. Experts also cautioned against slamming doors or placing hot pans on open doors, which can cause structural stress and thermal shock.
