Turn off equipment and access evaporator coil. If the coil is heavily soiled with lint, dirt, etc., use a brush to remove as much as possible prior to cleaning. When using Evap Power-C, prepare a cleaning solution in one of the quality Nu-Calgon sprayers, mixing one part of Evap Power-C with three parts of water. Be sure nearby registers are closed. Although the blower was turned off, natural air currents could pick up and entrain droplets of cleaning solution and this should be controlled.
