It was left to me on Saturday to set off the washing machine and I
happened to have my reading glasses on, which allowed me to notice
that the gel balls I was using were suitable for a 30 degree wash.
When I told my wife of this she said that washing at low temperatures
is a bad idea because the detergents etc. don't properly dissolve and
can end up clogging the outlet pipe.

Is there any truth in this?

Thanks

Edward
