Onions, peppers, fish, broccoli, and fried chicken taste great—but the leftover smells can be less than appetizing. Even if these foods are cooked perfectly, the odors they leave behind can linger well beyond the dishes being cleared and washed. Fortunately, you can use the same tips to get a burnt smell out of the house and remove stubborn food odors. In addition, make sure you’re keeping your fridge clear of odor-smelling foods for too long to keep the stench from invading other foods. 

To neutralize mildew smell, you can use natural deodorizers like baking soda or activated charcoal. Baking soda absorbs odors; sprinkle it liberally on the affected area, let it sit for a few hours, then vacuum it up. Activated charcoal, available in pouches, works similarly. Vinegar, with its natural acidic properties, can also neutralize odors. Mix equal parts water and vinegar, spray the affected area lightly, then blot it with a dry cloth. Enzymatic cleaners are effective too, breaking down odor-causing compounds.

To maintain your mattress and keep it fresh, you should aim for a deep clean at least twice a year. However, if you have allergies, pets, or sweat heavily at night, you may want to clean it more frequently, such as every three to four months. In between deep cleanings, it's a good practice to vacuum the mattress surface regularly and spot-clean any stains as they occur. Using a mattress protector can significantly help by minimizing the buildup of allergens, dust mites, and bodily fluids, which can make your cleaning routine more effective. Remember to launder the protector regularly, as some dirt and sweat can still get through to the mattress.
