Time and again the cleaning/washing instructions are "use a mild detergent".
It's hard enough to work out what products are detergents let alone mild.
So without bothering with all the chemistry etc can someone provide some examples of what I should buy at the supermarket which is "a mild detergent" or if Fairy Liquid classifies then it's already in the kitchen cupboard alongside Bicarb of Soda, Soda crystals and bars of washing soap.
