Some laundry advice gets passed down like a family recipe. Some of it should stay in the past with the washboard.

Quick answer: cold water cleans most loads, more detergent isn't better, full loads save water and most clothes don't need washing after one wear.

The seven myths

1. "Hot water is always cleaner." Cold water cleans most everyday loads well, and heating water is a big share of laundry energy.^†
2. "More detergent, more clean." Extra detergent leaves residue (read it).
3. "Small loads are gentler." Half loads use more water per item. Run full loads (read it).
4. "Wash after every wear." Jeans, sweaters and pants can often go several wears (read it).
5. "Fabric softener is essential." Most people don't need it (read it).
6. "Dryers are the only way." Line drying is free and gentle (read it).
7. "Eco detergents don't work." Well-made eco formulas can clean well.

Grandma was right about a lot of things. Just not hot water.
