Here’s where it gets fun: citric acid—the same stuff that makes lemons sour—chews up iron like a toddler with a crayon. Run your water through a filter with a pouch of citric acid crystals, or squirt half a lemon into your washing machine. Boom, iron stains dissolve. Why? Because citric acid “chelates” the iron, which is chemistry-speak for “hugs it so hard the iron forgets to stick to your laundry.”
Warning: don’t overdo it. Too much citric acid will make your water taste like you’re drinking lemonade from a rusty lemon. Your coffee will become a bitter irony in both senses. Use a teaspoon per gallon for cleaning; for drinking, stick to aeration.
