Product Info


All Nerta soaps are applied through a high pressure foamer and need to be applied between 80 and 100:1 water to soap.

There are two types of foamer sold through Nerta

PA Foamer – these foamers are supplied with a 1 litre bottle.

Add between 150ml – 200ml soap to the bottle and fill the rest with water. Please ensure that the soap adjusting knob on top is turned fully clockwise.

Please note that these foamers are only rated to 2600 PSI / 180 BAR, should you pressure washer be rated over this please do not use.

Suttner Foamer – these foamers come with either a 1 or 2 litre bottle and have an integrated soap/water ratio mix adjuster on the foamer, this automatically mixes the soap and water at the correct ratios, therefore no mixing is required.

Please note that there are 4 models of Suttner foamers that need to be matched to the specification of your pressure washer namely pressure and flow.

Add pure Nerta soap and set the adjuster to setting 1 which will use around 2% soap and 98% water.
