Glass containers are generally considered to be food moth proof because they are non-porous and do not provide a suitable environment for food moths to lay their eggs and thrive. However, it is important to ensure that the glass containers have airtight seals to prevent any potential infestation. Additionally, it is important to thoroughly clean and inspect the containers before storing food to ensure that there are no existing moth eggs or larvae present. **

Food storage containers and plastic utensils become greasy in the dishwasher because the high temperatures and strong detergents used in the dishwasher can sometimes break down oils and fats from the food residue left on the items. This can cause the oils to spread and coat the surfaces of the containers and utensils, leaving them feeling greasy. To prevent this, it's important to scrape off excess food before loading items into the dishwasher and to use a dishwasher detergent specifically designed to cut through grease. **

To seal open wet food cans airtight, you can use a can sealer or a vacuum sealer. A can sealer is a device specifically designed to seal cans airtight by crimping the edges of the can to create a tight seal. A vacuum sealer, on the other hand, removes air from the can and then seals it with a heat-sealing strip, creating an airtight environment. Both methods are effective in preserving the freshness of the food and preventing spoilage. **
