I switched from Aldi non-bio to Sainsbury's non-bio because the Aldi powder didn't dissolve properly.
Sainsbury's have changed their packaging (smaller box, similar number of washes) and the dosage quantities have decreased. I did two washes today, using the recommended amount of powder, and both washes left a large quantity of partially dissolved white crust in the dispensing tray.
Has anybody else had problems with Sainsbury's new detergent?
