I put my machine through a bleach wash earlier (90 degrees, empty), followed by towels on a 60 (always do it this way to make sure no bleach trace left for dark wash) I forgot to put liquid in (use a dispenser in drum) so thought not much of it, but then also forgot when I did the dark wash next! I did put softener in though and the stuff has come out absolutely fine!
Is it reasonable to not use any washing stuff except on a white wash- will save me a fortune!!
