Laundry
“Wet laundry left in a machine, even for a short amount of time, can cause germs to flourish. You should transfer clean clothes to the dryer immediately after each wash. If clothes sit in the washer for more than 30 minutes, you may want to run a second cycle.”

Pets
“Pets can also bring germs and bacteria in your home, especially if they go outside. According to a study conducted by the NSF, pet bowls placed fourth in hot spots with the most germs in a home. Pet toys also carried staph, yeast and mold.”
