Do use a dry microfiber cloth to remove dust from window screens. The static electricity generated by the dry synthetic fibers pulls the dust out of the mesh without making mud. Do you have window screens where you live?

Do check your car's cabin air filter located behind the glove box once a year. A clogged filter restricts your AC and heating airflow, making your car feel stuffy and causing windows to fog up easily. Some cars might have it in a different place. Check your owner's manual. Do you own a car?

Do keep your wireless router away from large household mirrors. The metallic backing material used inside glass mirrors reflects and scatters radio frequencies, creating weird dead zones in your home Wi-Fi signal. Do you have a router and internet?

Do check your home's water heater for a sacrificial anode rod every five years. This cheap metal rod intentionally corrodes to protect the steel tank from rusting out; replacing it can double the life of your water heater. Have you ever replaced this in your water heater?

Do hit a stubborn, rusted screw with a hammer a few times before trying to unscrew it. This "shock axial loading" cracks the rust bonds inside the threads, making it much easier to back out. Have you ever tried to remove a rusty screw? (And do make sure you are up to date on your tetanus shot before messing with anything rusty)

Do mash a single, small boiled potato into your homemade bread dough. The potato starches absorb and hold onto water much better than wheat flour, keeping your loaf incredibly soft and fresh for days longer. Do you bake your own bread sometimes?
