Can You Put Metal Racks or Skewers in a Microwave Grill?

When using a microwave grill, many people wonder whether it’s safe to use metal accessories like racks or skewers. The answer is: it depends — and using them incorrectly can damage your appliance or even cause sparks.

When It’s Safe to Use Metal in a Microwave Grill

Some microwave grill models are designed with a special metal rackA raised rack that allows air and heat to circulate around food for even grilling. included. These racks are coated or shaped in a way that prevents arcing (sparking) and are perfectly safe when used as directed in the manual.

Always ensure:

• The rack supplied by your microwave manufacturer is being used — not a random metal one.
• The rack doesn’t touch the sides or roof of the microwave cavity.
• The grill function (not standard microwave mode) is selected if the manual instructs so.

When Metal Becomes Dangerous

Ordinary metal skewers, racks, or foil pieces can cause arcingA type of electrical discharge that can spark and damage the microwave’s interior.. This happens when metal reflects microwaves, creating heat and sparks that can damage the interior or ignite food packaging.

• Metal skewers or utensils that touch the walls
