A recent article in the New York Times brought up an interesting subject: how much dishwasher detergent should we use? Every time my detergent runs low — which is often — I wonder how little can I get away with. As it turns out, "Washing machines and dishwashers are made to use far less water now than older models and, therefore, need less soap. And detergents have also become increasingly concentrated." So, the answer is less is more. What a relief! If you're a numbers girl (or boy) like me, you may need digits: the Times' expert dishwasher repairman says that 1/8 to 1/2 of what's usually recommended should be enough. Try this at home! It should save us all a pretty penny.
