You only need a teaspoon (5 ml) of Greenscents washing up liquid for a sink full of washing up. A smaller bowl (6 litres of water) requires only half a teaspoon (2.5 ml) of washing up liquid. For best results, use one squirt of washing up liquid while running warm water into your sink or bowl. This will encourage more bubbles to form. Clean your crockery and utensils with a cloth or brush and rinse. Then admire your glistening glass and shining crockery. Dry with a linen cloth or tea towel.
