Mr Dishwasher - Power of 4 Laundry and Dishwasher Detergent *South Australia*
Laundry Powder 5kg - $42
Dishwasher Powder 4kg - $49
These products are concentrated and designed for Adelaide's hard water, so with each tub giving you around 250 washes, this works out at around 5-6c per wash.
The cheapest I have found apart from that for Laundry is Duo 1kg, which regularly goes on sale for $2 (but as you use more powder per load, you have to get 40 scoops out of your Duo packet to get the same cost per wash)
They only sell to Adelaide homes, but they will deliver for free within 40km of the cbd. (or you can buy at their store in the city)
They also sell other sizes and rinse aid (but we use vinegar and have found it to be just as effective as a rinse aid and LOTS cheaper)
you can order online, by phone or go into the store.
As to quality - we have always been very impressed with both the service and the quality of the product.
The laundry detergent is also suitable for front loaders.
