Environmentally friendly Surfactant for use as a cleaner in steamers and high-pressure washers for heavy-duty cleaning applications such as drilling rig cleaners and oilfield truck washers. Typical recommended dilution rates vary from 1 part of INC725 Surfactant per 100 parts of water, to as concentrated as 1 part INC725 in 20 parts of water. We recommend that at the lower dilution rates (as in 1:20) the resultant solution be tested in an inconspicuous location to determine if it will dull the paint.
