This is the spray I use:
5 liters of water
1 tablespoon of vegetable oil
one teaspoon of liquid soap or detergent
one teaspoon of sodium bicarbonate (I never weighed it)
Mix half the water (it should be rather warm) with soap and oil to get an 'emulsion', add the rest of the water (this should be cooler) and sodium bicarbonate at the end, mix thoroughly.
Spray the plants from top to bottom so they are literally dripping with it. Don't forget the underside of the leaves.
