To protect your hands, fingers from heat always use mitts before putting food in or taking out from the pizza oven.
Check the quality of the mitts before buying it. You should use mitts that are made of the padded material. You can buy them from kitchen stores.
You cannot use a standard spatula that you use when preparing food on a standard range. You need a spatula or paddle that has a long handle and can get inside of the appliance.
Most of the paddles are made from solid wood although you might find some of these crafted from stainless steel. You may want to choose one that is not too heavy for you to handle and can be stored in your home.
If you have a fire burning model, shovel out all the ashes. Leaving ashes in there could cause the fire to get out of control or perhaps not even start when you will make pizzas again.
You may wish to wipe down the hearth and entire appliance with a diluted bleach solution and water. This cleansing step will remove dangerous bacteria and help you prevent crosscontamination.
If you are using Wood Pizza Oven or any other pizza oven these measures will help you prevent injuries to you and your loved ones.
