Coles Ultra Coffee Machine Descaler

If ever there was a classic scam, this product is a good example. It retails for $4 for a 250ml bottle. It is nothing more than watered down vinegar. You can buy a 2 litre bottle of white vinegar a few aisles over for half that and save yourself a lot of money. If you have your doubts about my claim, buy a bottle pout it its contents into a jug and sprinkle in a teaspoon of bicarb soda and see what happens. If that isn’t proof enough the smell will be when you run this stuff through your espresso machine.

Do the maths and see what a scam this is.
