Wondering about soap ratios when using a foam cannon?

Questions about the mixing ratio between water and soap are one of the questions we get most often.

It is difficult to give a completely accurate answer here as there are many factors that come into play.

• High powered washers tend to deliver more water than smaller washers. This leads to the mixing ratio between water and soap often being somewhat lower in the larger machines, as the soap absorption in the foam cannon is relatively stable.
• The viscosity (thickness) of the soap can affect how quickly it is drawn up by the foam cannon. The thicker the soap, the lower the mixing ratio.
• The effect in a single machine varies between different user locations, due to variations in the voltage in the mains. This also affects the consumption of soap.

Since there are several factors that influence the result, the following procedure is a good starting point:

1. Read what's on the bottle. Most manufacturers usually specify a mixing ratio between soap and water. It is not uncommon for several mixing ratios to be specified depending on the method of application or the desired effect of the agent.
2. Start with the foam cannon's highest mixing ratio. If the manufacturer of the soap recommends e.g. 2% mixing ratio, our brass cannon will deliver 5% if you use the soap undiluted. If you mix the soap with water, e.g. 1:1 you then have a 50% soap mixture. When using our brass canon at maximum, the mixing ratio will then be 2.5% (5% of 50% is equal to 2.5%).
3. Now you are ready to wash. Start with the setting close to minimum on the foam cannon. Perhaps give the cannon a go on a small area before starting the whole job.
4. If the foam is too thin, gradually increase the supply by adjusting of the foam cannon until it produces a satisfactory foam.
