So what do washing machines use, AC or DC?


Water and some sort of cleaning chemicals dependent on personal choice.


A few years ago Which? reviewed a washing machine that didn't use
detergent: it sort of passed an electric current through the water. I
don't know how good it was: apparently washing normally with detergent
uses some kind of electric charge to clean fabric as just passing the
water through the fibres isn't enough to remove the dirt.


Do you have a link? Google ain't working.
