Kitchen towels should be washed after significant use or every week in order to prevent food-borne illnesses. The rules are somewhat less strict for bathroom towels, but they should still be washed frequently, around every 3 to 5 days to help avoid any build-up of bacteria. Other recommendations say bathroom towels should be washed after every three uses.

To clean an old dishwasher without a filter, start by removing the bottom rack to access the drain area. Use a damp cloth or sponge to wipe down the interior, paying special attention to the corners and crevices where food particles and debris can build up. Pour a cup of white vinegar into a dishwasher-safe bowl and place it on the top rack, then run a hot water cycle to help break down grease and grime. After the cycle, sprinkle a cup of baking soda across the bottom of the dishwasher and run a short hot water cycle to deodorize and further clean the interior. 

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.

You can clean your bathroom like a professional by keeping your cleaning tools and products organized and having a cleaning plan or routine. Most cleaning pros start by dusting and sweeping first and applying cleaning solutions. You should let the solutions sit in your bathtub, shower, sink, and toilet, and wipe everything down with fresh cleaning cloths. A final mop gives the finishing touch.
