A ½ gallon bottle of concentrate can make 16 gallons of pressure washer solution (at 4 oz concentrate per gallon of water). The ratio is 32:1.

In the case of the pressure washer TSV, the MTS-1300PW’s detergent bottle is 13.5 fl oz.

This means that you can re-fill the included detergent bottle at least 150 times from 1 purchase of MTS-PWC3X.
