Old Fashion’s 200 ml foamer bottles are generally filled with about 1 fl oz of liquid soap and topped off with water. The pumping mechanism works to convert your diluted soapy mixture to piles of foam! Just pump like a normal dispenser and you will have a handful of foam in just a few downward strokes. The best part is your soap goes a long way! Super economical for any person needing to dispense soap!
Most types of liquid soap base will work.
