Don't stow in your car's glove compartment during the summer. Otherwise, batteries may overheat, possibly ruining the phone. If you've been known to drop your cell phone, treat it to a protective case.
Clean the lint filter after each use and the entire air duct yearly. If your dryer breaks, think about replacing it if repairs will cost more than half the price of a comparable new model. But don't expect much gain in performance or efficiency, since dryer technology hasn't changed much.
Don't overload. If your washer breaks, think about replacing it if repairs will cost more than half the price of a comparable model. If you're replacing, consider a high-efficiency washer, which should save money over time. Also consider a front-loader, which is less punishing to clothes than a top-loader.
Check the filter regularly and remove any debris.
To see additional suggestions and reminders,
Dust mop or vacuum weekly. Wipe up wet spills pronto.
Keep them out of the dishwasher and store them in a wooden knife block or individual plastic shields.
Set them on a hard, flat surface rather than a soft one such as a bed or carpet, which can block airflow and cause them to overheat.
Clean the screen gently with a soft, slightly damp cloth, ideally a microfiber one. Avoid commercial cleaners and paper towels, which can scratch the screen.
Rotate periodically. Try not to sit on the edge. Buy a washable, protective cover. And pull back the sheets and blankets to let the bed air out for 20 minutes or so each morning.
