Why is there powder/tablets on my clothes at the end of the washing cycle?

In our experience loading too many items into the washing machine can leave insufficient space in the drum for the detergent to dissolve properly. Sometimes, it can get caught in the middle of the wash load leaving streaks of undissolved detergent or a film on the items. Incorrect dosing of the detergent can also be a factor as well as insufficient waterfill for the size of the wash load. It is vital that the correct amount of detergent is used. Several factors need to be taken into consideration: size of wash load; level of soiling on the items; correct wash cycle; water hardness.

Re-washing should remove any residue powder or tablets.
