Conserve water when you wash your car. Clean your car using a hose with a nozzle so that you can easily shut off the water when you don’t need it. Better yet, use a bucket instead of a hose to save even more water. Or look for a commercial car wash that recycles water.
Put your dishwasher to work. Washing dishes by hand generally uses more water than a modern dishwasher. Scrape your plates instead of rinsing them and load it up! Just be sure to wait until you have a full load it run it.
