Washing tips:

  • Wash one large load instead of two medium loads (though don’t overload your machine). Check your machine’s manual for load capacity in pounds, then weigh out a few loads of laundry to get a sense of how much laundry your machine can handle.
  • Adjust water level to the lowest practical setting.
  • Use the shortest cycle needed.
  • Avoid using too much detergent to eliminate the need for extra rinse, it’s also better for your clothes.
  • Wash and rinse temperatures have a dramatic impact on overall energy use; a hot water wash with warm rinse costs 5 to 10 times more than a cold wash and rinse.
  • Turn down the thermostat on your water heater. A setting of 120 F is adequate for most home needs. By reducing your hot water temperature, you will save energy with either hot or warm wash cycles.
  • The temperature of the rinse water does not affect cleaning, so always set the washing machine on cold water rinse.
  • Pre-soak, especially dirty clothes–by pre-soaking heavily soiled clothes, a cooler wash temperature may be fine.
  • Experiment with different laundry detergents to find one that works well with cooler water.

To remove sweat stains from the under-arms of shirts and blouses, wet garment stain before washing and rub in a bit of toothpaste.
Launder as usual - that is, on machine settings appropriate for the material.

May have to be repeated if the sweat stain is extensive, but usually that will take care of it. (And the toothpaste "smell" only lasts a few minutes.)

this turning down the thermostat on your h/w heater is for the birds!! I want HOT water not lukewram water in my shower and when I wash my dishes by money? If your h/w heater is electric, like mine is, TURN IT OFF at the circuit breaker when not in use!! I turn mine on about 20-30 min. before I need water and save up to $50 on my elec. bill!!
