Put the tube into a bucket with detergent that is recommended for your machine then put the wand into low pressure mode and if it has a valve where the hose connects turn the valve to the on position and pull trigger and watch to see if soap starts being drawn out of the soap bottle if it starts pulling the soap up continue to allow it to flow till you get your part soaked with soap, then let it set for 10 minutes then hit it with high pressure hose to wash off, when it is clean then put it on low pressure and pull hose out of bucket with soap and then allow the soap to be pulled out of tube and until there is no longer any soap coming out then store the hose for use later. some machines have a control valve at the end of the wand by turning the tip or pushing tip in or pulling it out some models requires you to use quick disconnect fan tips to lower pressure to use soap.
