The foam will need to be in contact with the scum for a period of time (at least two hours is ideal) to be most effective. The product may be dispensed with the can in any orientation. Use in a well-ventilated area and avoid
breathing spray mist. To coat scummy surfaces with foam, hold the can about 18” away from the surface and apply in a sweeping motion. To inject into drains,
position the can upside down with the nozzle directly over an opening in the drain grate and dispense foam. Likewise, in other areas where a straighter stream versus
a fan spray is desired, position the can closer to the target area when applying. Foam cracks, crevices, drains and other scummy areas where organic build-up has
occurred.
